Downloads][npm-downloads-image]][node-url] +[![Build Status][ci-image]][ci-url] +[![Test Coverage][coveralls-image]][coveralls-url] + +## Installation + +This is a [Node.js](https://nodejs.org/en/) module available through the +[npm registry](https://www.npmjs.com/). Installation is done using the +[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): + +```sh +$ npm install express-session +``` + +## API + +```js +var session = require('express-session') +``` + +### session(options) + +Create a session middleware with the given `options`. + +**Note** Session data is _not_ saved in the cookie itself, just the session ID. +Session data is stored server-side. + +**Note** Since version 1.5.0, the [`cookie-parser` middleware](https://www.npmjs.com/package/cookie-parser) +no longer needs to be used for this module to work. This module now directly reads +and writes cookies on `req`/`res`. Using `cookie-parser` may result in issues +if the `secret` is not the same between this module and `cookie-parser`. + +**Warning** The default server-side session storage, `MemoryStore`, is _purposely_ +not designed for a production environment. It will leak memory under most +conditions, does not scale past a single process, and is meant for debugging and +developing. + +For a list of stores, see [compatible session stores](#compatible-session-stores). + +#### Options + +`express-session` accepts these properties in the options object. + +##### cookie + +Settings object for the session ID cookie. The default value is +`{ path: '/', httpOnly: true, secure: false, maxAge: null }`. + +The following are options that can be set in this object. + +##### cookie.domain + +Specifies the value for the `Domain` `Set-Cookie` attribute. By default, no domain +is set, and most clients will consider the cookie to apply to only the current +domain. + +##### cookie.expires + +Specifies the `Date` object to be the value for the `Expires` `Set-Cookie` attribute. +By default, no expiration is set, and most clients will consider this a +"non-persistent cookie" and will delete it on a condition like exiting a web browser +application. + +**Note** If both `expires` and `maxAge` are set in the options, then the last one +defined in the object is what is used. + +**Note** The `expires` option should not be set directly; instead only use the `maxAge` +option. + +##### cookie.httpOnly + +Specifies the `boolean` value for the `HttpOnly` `Set-Cookie` attribute. When truthy, +the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` +attribute is set. + +**Note** be careful when setting this to `true`, as compliant clients will not allow +client-side JavaScript to see the cookie in `document.cookie`. + +##### cookie.maxAge + +Specifies the `number` (in milliseconds) to use when calculating the `Expires` +`Set-Cookie` attribute. This is done by taking the current server time and adding +`maxAge` milliseconds to the value to calculate an `Expires` datetime. By default, +no maximum age is set. + +**Note** If both `expires` and `maxAge` are set in the options, then the last one +defined in the object is what is used. + +##### cookie.path + +Specifies the value for the `Path` `Set-Cookie`. By default, this is set to `'/'`, which +is the root path of the domain. + +##### cookie.sameSite + +Specifies the `boolean` or `string` to be the value for the `SameSite` `Set-Cookie` attribute. +By default, this is `false`. + + - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + - `false` will not set the `SameSite` attribute. + - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement. + - `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie. + - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + +More information about the different enforcement levels can be found in +[the specification][rfc-6265bis-03-4.1.2.7]. + +**Note** This is an attribute that has not yet been fully standardized, and may change in +the future. This also means many clients may ignore this attribute until they understand it. + +**Note** There is a [draft spec](https://tools.ietf.org/html/draft-west-cookie-incrementalism-01) +that requires that the `Secure` attribute be set to `true` when the `SameSite` attribute has been +set to `'none'`. Some web browsers or other clients may be adopting this specification. + +##### cookie.secure + +Specifies the `boolean` value for the `Secure` `Set-Cookie` attribute. When truthy, +the `Secure` attribute is set, otherwise it is not. By default, the `Secure` +attribute is not set. + +**Note** be careful when setting this to `true`, as compliant clients will not send +the cookie back to the server in the future if the browser does not have an HTTPS +connection. + +Please note that `secure: true` is a **recommended** option. However, it requires +an https-enabled website, i.e., HTTPS is necessary for secure cookies. If `secure` +is set, and you access your site over HTTP, the cookie will not be set. If you +have your node.js behind a proxy and are using `secure: true`, you need to set +"trust proxy" in express: + +```js +var app = express() +app.set('trust proxy', 1) // trust first proxy +app.use(session({ + secret: 'keyboard cat', + resave: false, + saveUninitialized: true, + cookie: { secure: true } +})) +``` + +For using secure cookies in production, but allowing for testing in development, +the following is an example of enabling this setup based on `NODE_ENV` in express: + +```js +var app = express() +var sess = { + secret: 'keyboard cat', + cookie: {} +} + +if (app.get('env') === 'production') { + app.set('trust proxy', 1) // trust first proxy + sess.cookie.secure = true // serve secure cookies +} + +app.use(session(sess)) +``` + +The `cookie.secure` option can also be set to the special value `'auto'` to have +this setting automatically match the determined security of the connection. Be +careful when using this setting if the site is available both as HTTP and HTTPS, +as once the cookie is set on HTTPS, it will no longer be visible over HTTP. This +is useful when the Express `"trust proxy"` setting is properly setup to simplify +development vs production configuration. + +##### genid + +Function to call to generate a new session ID. Provide a function that returns +a string that will be used as a session ID. The function is given `req` as the +first argument if you want to use some value attached to `req` when generating +the ID. + +The default value is a function which uses the `uid-safe` library to generate IDs. + +**NOTE** be careful to generate unique IDs so your sessions do not conflict. + +```js +app.use(session({ + genid: function(req) { + return genuuid() // use UUIDs for session IDs + }, + secret: 'keyboard cat' +})) +``` + +##### name + +The name of the session ID cookie to set in the response (and read from in the +request). + +The default value is `'connect.sid'`. + +**Note** if you have multiple apps running on the same hostname (this is just +the name, i.e. `localhost` or `127.0.0.1`; different schemes and ports do not +name a different hostname), then you need to separate the session cookies from +each other. The simplest method is to simply set different `name`s per app. + +##### proxy + +Trust the reverse proxy when setting secure cookies (via the "X-Forwarded-Proto" +header). + +The default value is `undefined`. + + - `true` The "X-Forwarded-Proto" header will be used. + - `false` All headers are ignored and the connection is considered secure only + if there is a direct TLS/SSL connection. + - `undefined` Uses the "trust proxy" setting from express + +##### resave + +Forces the session to be saved back to the session store, even if the session +was never modified during the request. Depending on your store this may be +necessary, but it can also create race conditions where a client makes two +parallel requests to your server and changes made to the session in one +request may get overwritten when the other request ends, even if it made no +changes (this behavior also depends on what store you're using). + +The default value is `true`, but using the default has been deprecated, +as the default will change in the future. Please research into this setting +and choose what is appropriate to your use-case. Typically, you'll want +`false`. + +How do I know if this is necessary for my store? The best way to know is to +check with your store if it implements the `touch` method. If it does, then +you can safely set `resave: false`. If it does not implement the `touch` +method and your store sets an expiration date on stored sessions, then you +likely need `resave: true`. + +##### rolling + +Force the session identifier cookie to be set on every response. The expiration +is reset to the original [`maxAge`](#cookiemaxage), resetting the expiration +countdown. + +The default value is `false`. + +With this enabled, the session identifier cookie will expire in +[`maxAge`](#cookiemaxage) since the last response was sent instead of in +[`maxAge`](#cookiemaxage) since the session was last modified by the server. + +This is typically used in conjuction with short, non-session-length +[`maxAge`](#cookiemaxage) values to provide a quick timeout of the session data +with reduced potential of it occurring during on going server interactions. + +**Note** When this option is set to `true` but the `saveUninitialized` option is +set to `false`, the cookie will not be set on a response with an uninitialized +session. This option only modifies the behavior when an existing session was +loaded for the request. + +##### saveUninitialized + +Forces a session that is "uninitialized" to be saved to the store. A session is +uninitialized when it is new but not modified. Choosing `false` is useful for +implementing login sessions, reducing server storage usage, or complying with +laws that require permission before setting a cookie. Choosing `false` will also +help with race conditions where a client makes multiple parallel requests +without a session. + +The default value is `true`, but using the default has been deprecated, as the +default will change in the future. Please research into this setting and +choose what is appropriate to your use-case. + +**Note** if you are using Session in conjunction with PassportJS, Passport +will add an empty Passport object to the session for use after a user is +authenticated, which will be treated as a modification to the session, causing +it to be saved. *This has been fixed in PassportJS 0.3.0* + +##### secret + +**Required option** + +This is the secret used to sign the session ID cookie. This can be either a string +for a single secret, or an array of multiple secrets. If an array of secrets is +provided, only the first element will be used to sign the session ID cookie, while +all the elements will be considered when verifying the signature in requests. The +secret itself should be not easily parsed by a human and would best be a random set +of characters. A best practice may include: + + - The use of environment variables to store the secret, ensuring the secret itself + does not exist in your repository. + - Periodic updates of the secret, while ensuring the previous secret is in the + array. + +Using a secret that cannot be guessed will reduce the ability to hijack a session to +only guessing the session ID (as determined by the `genid` option). + +Changing the secret value will invalidate all existing sessions. In order to rotate +the secret without invalidating sessions, provide an array of secrets, with the new +secret as first element of the array, and including previous secrets as the later +elements. + +##### store + +The session store instance, defaults to a new `MemoryStore` instance. + +##### unset + +Control the result of unsetting `req.session` (through `delete`, setting to `null`, +etc.). + +The default value is `'keep'`. + + - `'destroy'` The session will be destroyed (deleted) when the response ends. + - `'keep'` The session in the store will be kept, but modifications made during + the request are ignored and not saved. + +### req.session + +To store or access session data, simply use the request property `req.session`, +which is (generally) serialized as JSON by the store, so nested objects +are typically fine. For example below is a user-specific view counter: + +```js +// Use the session middleware +app.use(session({ secret: 'keyboard cat', cookie: { maxAge: 60000 }})) + +// Access the session as req.session +app.get('/', function(req, res, next) { + if (req.session.views) { + req.session.views++ + res.setHeader('Content-Type', 'text/html') + res.write('

views: ' + req.session.views + '

') + res.write('

expires in: ' + (req.session.cookie.maxAge / 1000) + 's

') + res.end() + } else { + req.session.views = 1 + res.end('welcome to the session demo. refresh!') + } +}) +``` + +#### Session.regenerate(callback) + +To regenerate the session simply invoke the method. Once complete, +a new SID and `Session` instance will be initialized at `req.session` +and the `callback` will be invoked. + +```js +req.session.regenerate(function(err) { + // will have a new session here +}) +``` + +#### Session.destroy(callback) + +Destroys the session and will unset the `req.session` property. +Once complete, the `callback` will be invoked. + +```js +req.session.destroy(function(err) { + // cannot access session here +}) +``` + +#### Session.reload(callback) + +Reloads the session data from the store and re-populates the +`req.session` object. Once complete, the `callback` will be invoked. + +```js +req.session.reload(function(err) { + // session updated +}) +``` + +#### Session.save(callback) + +Save the session back to the store, replacing the contents on the store with the +contents in memory (though a store may do something else--consult the store's +documentation for exact behavior). + +This method is automatically called at the end of the HTTP response if the +session data has been altered (though this behavior can be altered with various +options in the middleware constructor). Because of this, typically this method +does not need to be called. + +There are some cases where it is useful to call this method, for example, +redirects, long-lived requests or in WebSockets. + +```js +req.session.save(function(err) { + // session saved +}) +``` + +#### Session.touch() + +Updates the `.maxAge` property. Typically this is +not necessary to call, as the session middleware does this for you. + +### req.session.id + +Each session has a unique ID associated with it. This property is an +alias of [`req.sessionID`](#reqsessionid-1) and cannot be modified. +It has been added to make the session ID accessible from the `session` +object. + +### req.session.cookie + +Each session has a unique cookie object accompany it. This allows +you to alter the session cookie per visitor. For example we can +set `req.session.cookie.expires` to `false` to enable the cookie +to remain for only the duration of the user-agent. + +#### Cookie.maxAge + +Alternatively `req.session.cookie.maxAge` will return the time +remaining in milliseconds, which we may also re-assign a new value +to adjust the `.expires` property appropriately. The following +are essentially equivalent + +```js +var hour = 3600000 +req.session.cookie.expires = new Date(Date.now() + hour) +req.session.cookie.maxAge = hour +``` + +For example when `maxAge` is set to `60000` (one minute), and 30 seconds +has elapsed it will return `30000` until the current request has completed, +at which time `req.session.touch()` is called to reset +`req.session.cookie.maxAge` to its original value. + +```js +req.session.cookie.maxAge // => 30000 +``` + +#### Cookie.originalMaxAge + +The `req.session.cookie.originalMaxAge` property returns the original +`maxAge` (time-to-live), in milliseconds, of the session cookie. + +### req.sessionID + +To get the ID of the loaded session, access the request property +`req.sessionID`. This is simply a read-only value set when a session +is loaded/created. + +## Session Store Implementation + +Every session store _must_ be an `EventEmitter` and implement specific +methods. The following methods are the list of **required**, **recommended**, +and **optional**. + + * Required methods are ones that this module will always call on the store. + * Recommended methods are ones that this module will call on the store if + available. + * Optional methods are ones this module does not call at all, but helps + present uniform stores to users. + +For an example implementation view the [connect-redis](http://github.com/visionmedia/connect-redis) repo. + +### store.all(callback) + +**Optional** + +This optional method is used to get all sessions in the store as an array. The +`callback` should be called as `callback(error, sessions)`. + +### store.destroy(sid, callback) + +**Required** + +This required method is used to destroy/delete a session from the store given +a session ID (`sid`). The `callback` should be called as `callback(error)` once +the session is destroyed. + +### store.clear(callback) + +**Optional** + +This optional method is used to delete all sessions from the store. The +`callback` should be called as `callback(error)` once the store is cleared. + +### store.length(callback) + +**Optional** + +This optional method is used to get the count of all sessions in the store. +The `callback` should be called as `callback(error, len)`. + +### store.get(sid, callback) + +**Required** + +This required method is used to get a session from the store given a session +ID (`sid`). The `callback` should be called as `callback(error, session)`. + +The `session` argument should be a session if found, otherwise `null` or +`undefined` if the session was not found (and there was no error). A special +case is made when `error.code === 'ENOENT'` to act like `callback(null, null)`. + +### store.set(sid, session, callback) + +**Required** + +This required method is used to upsert a session into the store given a +session ID (`sid`) and session (`session`) object. The callback should be +called as `callback(error)` once the session has been set in the store. + +### store.touch(sid, session, callback) + +**Recommended** + +This recommended method is used to "touch" a given session given a +session ID (`sid`) and session (`session`) object. The `callback` should be +called as `callback(error)` once the session has been touched. + +This is primarily used when the store will automatically delete idle sessions +and this method is used to signal to the store the given session is active, +potentially resetting the idle timer. + +## Compatible Session Stores + +The following modules implement a session store that is compatible with this +module.

Here `mitmproxy` is used for reasons that will be clear later. + +When the `GET FLAG` button is pressed, we find that there are two requests made by the phone, one POST request to `/getKey` and one POST request to `/getFlag`. + +![api](api.png) + +We saw that the request to `/getKey` sends a `code` and returns a `rsa_e` = 65537 and a `rsa_n` (= $630\cdots 1967$. For `/getFlag`, the device sends a `key` which is a base64-encoded string, and another `code` (which is different from the `/getKey` `code`), and received a `aes_cbc_iv` and `enc_flag` respectively, and the `enc_flag` is the string shown on the device. Running the request for a few times, we can see that `rsa_n` and `rsa_e` are the same everytime, while `key` is different each time. Also note that the code is sometimes the same for their respective API call. If you try it long enough you will even find that the `code` from `/getKey` 30 minutes ago would match the `code` in `/getFlag` (though it is not so important here). + +### RSA + +`mitmproxy` is an "active" TLS man-in-the-middle which allows us to not only read the contents of the HTTP requests, but also modify them. If we modify the `code`, we find that `GET FLAG` will fail. If we modify the response of `/getKey`, then `/getFlag` will fail. If we modify `rsa_e`, `/getFlag` may still be sent, but if we modify `rsa_n`, `/getFlag` may not even be sent at all. + +The parameters in `/getKey` is suggestive that the server is sending some kind of *RSA public key* to the device (since `rsa_n` and `rsa_e` sounds like the `n` and `e` in the RSA public key, which are the modulus and the public exponent respectively). + +To verify our hypothesis, let's use the following script to modify the `rsa_e` to `1`. This, however, will not work (because android do not support `e=1` so the device will throw an error) However, we can set `rsa_e` to be 3. Here we notice that the `key` sent by the client is base64-encoded, and the leading bytes are `A`'s. Decoding the `key` reveals that the leading `A`'s are actually null bytes in front, thus the decoded key is actually just a small integer (compared to the modulus). Thus we can try to take the cubic root to reveal the content of `key`, which is actually some 32-byte long bytestring. + +![AAA](AAA.png) + +```python +from mitmproxy import ctx +from mitmproxy import http +from base64 import b64decode +import decimal + + +class MiddleRoad: + def __init__(self): + pass + + def request(self, flow: http.HTTPFlow) -> None: + if flow.request.pretty_url.endswith("getFlag"): + key_b64 = flow.request.urlencoded_form["key"] + key_int = int.from_bytes(b64decode(key_b64), 'big') + # Take the cubic-root of key + decimal.getcontext().prec = len(str(key_int)) + c_decimal = decimal.Decimal(key_int) + decrypt_m = int((c_decimal**(decimal.Decimal(1)/decimal.Decimal(3))).quantize(decimal.Decimal('1.0'))) + ctx.log.info(decrypt_m.to_bytes(32, 'big')) + + + + def response(self, flow: http.HTTPFlow) -> None: + if flow.request.pretty_url.endswith("getKey"): + flow.response.content = flow.response.content.replace(b'"rsa_e":"65537"', b'"rsa_e":"3"') + +addons = [MiddleRoad()] +``` + + + + + +### AES + +Now for a moment we remove the script and inspect the contents in `/getFlag`. `aes_cbc_iv` seems to suggest *AES-CBC* encryption (where the `iv` serves as the *initial vector* in AES-CBC).
