+# cell
+
+Author: Aneesh Maganti
+
+This challenge presents itself as a controller testing program written as PS3 homebrew (compiled using PSL1GHT via the flipacholas/ps3devextra docker image). Of course, there's more than meets the eye here. This challenge has three main stages to it: recognizing and setting up the environment required, reversing the challenge to determine what its functionality, and then finally passing the challenge to get the final set of registers. 
+
+The file cell.pkg can refer to many files as outlined [here](https://en.wikipedia.org/wiki/.pkg) - the name itself though is a reference to the [unique](https://en.wikipedia.org/wiki/Cell_(processor)) processor the PS3 had. While this file can be loaded on an actual PS3, it is significantly easier to use an emulator when working. RPCS3 is a popular emulator with high compatibility so it was used when testing.
+
+Loading the file initially presents the user with a controller test program (note: the base controller homebrew came from [here](https://www.psx-place.com/threads/ps3-gamepad-test.144/)). However, every 2 seconds, it will poll for your controller inputs and print out to the TTY console. To progress from here, you will need to decompile the program. The base file, cell.pkg, is a packed version of a digital PSN game so you'll first want to extract it. You can use [PS3 Game Extractor](https://www.psx-place.com/resources/ps3-game-extractor.824/) to unpack the .pkg file; you'll find an eboot.bin file which is the main executable of the program, albeit encrypted. To decrypt the binary, you can use a utility in RPCS3 to decrypt the file, generating an eboot.elf file. To disassemble this, there are scripts both for [IDA](https://github.com/kakaroto/ps3ida) and [Ghidra](https://github.com/clienthax/Ps3GhidraScripts). However, the IDA scripts are pretty oudated now and (to my knowledge) don't allow you to decompile the program; therefore, I went with Ghidra.
+
+You'll want to apply the analysis scripts before analyzing the program. This will show you some of the Cell (not to be confused with the program name) libraries that the PS3 uses for OS functions including drawing to the screen, doing console logs, etc. You can find the entrypoint, start for PS3, which is referred to as TOC_BASE in Ghidra. From here, you can trace down the functions until you find the main function (from the original C source files). You'll need to interpret the general structure from the program here.

+
+Cell works by polling your inputs every 2 seconds and then comparing this set of inputs to a large buffer part of the binary. Each set is exactly 2 inputs: any of the triggers, L3/R3, no input, and the face buttons. The correct set of inputs is below:
+
+1) Triangle/Cross
+2) L1/R1
+3) L2/R2
+4) Triangle/Start
+5) L1/Square
+6) R2
+7) R1/L3
+8) R3
+
+If the inputs are all matched to the end, then cell will hang and ask you to check the registers. You can use RPCS3 to pull up the registers and view them directly. After copying these values, you can then call the python script and enter in the corresponding values; if they all match, you will be presented with the flag.

+# Writeup
+
+Imagine two parts of a computer system, Nginx and Node.js. Nginx has rules that say, "Don't let anyone visit the `/ram` page." However, Node.js has a special way of understanding web addresses. It can sometimes "ignore" certain characters in the address.
+
+Nginx is configured with rules to deny access to the `/profile/ram` and `/profile/ram/` endpoints. However, Node.js, using Express, employs character normalization that "ignores" specific characters like `\x09`, `\xa0`, and `\x0c` from the URL.
+
+Got the point? Nginx includes these characters in the URL, while Node.js removes them. As a result, Nginx forwards HTTP requests to the backend when it should deny them, effectively bypassing the ACL rules.
+
+**Solution**
+
+- Use hex `\xA0` at the end of profile: `GET /profile/ram\xA0 HTTP/1.1`
+- Now, Nodejs will trim `\xA0` and NGINX will allow this character as we are using `location = /profile/ram` (equals to some parameter)
+
+**Fix**
+Alright, so this may not be as crucial as the meaning of life or finding the perfect pizza topping, but it's helpful nonetheless, so here we go!
+
+- Use this instead of equal sign `location ~* ^/ram`.
+- This expression will check for `ram` string in the URL. If that word is present, it will block it!

+Given this binary and running, we get an output of the files on some ftp server somewhere. We can't do anything else with the binary as it doesn't take input and purely does this operation.

+When we run the file, we get a string output:

+Rust does not have much work done in terms of decompiling tools so we can be tactical with how we try get some info from this binary. 
+As we can see, these strings must be residing at some memory address. Possibly near some other important info as they will probably be close in memory addresses.

+```
+
+We can find the creds.
+
+We can now ftp in where there is one file, note.txt giving info. 
+
+## Step 2
+Doing some reconnaissance on this ip, we see a web server running on a port. Heading over to it, we see a login portal.
+
+Analyse how the requests are sent by intercepting. Will notice there is a request to /initiateRateLimit which causes the ratelimiting. So if we just make our requests and observe the response, we can determine if the password is correct beforehand and also observe the errorcode.
+
+Determine that the errorcode represents the number of chars from the beginning that match the user password. Write a script that fuzzes printable characters until a match is found, then proceed to next char until password found.
+
+Solver script in solver.py
+
+Truncated Tail of Output
+```
+...
+...
+Processing char: V
+Password: ppXr5yGXe2g83
+Found. Redirecting to http://localhost:3000/issueRateLimit?u=user&p=ppXr5yGXe2g83W&error=13
+Processing char: W
+Password: ppXr5yGXe2g83
+Found. Redirecting to http://localhost:3000/issueRateLimit?u=user&p=ppXr5yGXe2g83X&error=14
+Processing char: X
+Password: ppXr5yGXe2g83X
+{"msg":"ftp_dev:vOc!&6k(G;uNSqjQBt=M"}
+```
+
+## Step 3
+Now when we ftp in, we now have more privs than before. We can see the node server code. 
+
+There is an RCE exploit within the time logging functionality of the server that only executes when the ratelimiting is triggered. There is an optional t parameter that can be manually overwritten which represents the time that a request was made for the logger. There is a vulnerable eval within the functionality. However, there is a safeguard function safeT(). You can reverse this obfuscation (see encryption-solver.js) and then can get the RCE.
