Let's see. Let's go to login. We can register an account. I'm going to do IPSC and I'm going to add bug bounty to the end of it.

Let's see. That's a 404 not found. Um, we could try doing just a custom like brute force inside of this directory, but it doesn't look like we're getting anything here. Um, let's go back to the water level trend and let's see if I remove my O token. Send it. It still works. So, we have a IOR vulnerability. | 350.08 | 0 | {

It's just this endpoint does not require any authentication. So, that's something I would look at. look at all the APIs it interacts with and see if there's anything we can do. Um, we did get tickets here. I don't know what that's doing. Um, controls again doesn't really look like anything special. So, let's go over to... | 375.84 | 0 | {

So, at this point, um I guess we can try like SQL injection. Uh let's go proxy where we posted. Send it. I'm going to put a um bunch of special characters to test for various things. We can copy it and put it for the description as well. | 419.039 | 0 | {

So, we have now submitted this. If we go uh back to get tickets, we can see it's just listing all of our tickets. Um, we have the authorization in two different places. We have it in the cookie and the body here. If we delete it out of both, I'm going to test for an ID door vulnerability again, we get unauthorized. So ... | 449.039 | 0 | {

Then you can paste the token in and then it has a nice um display, right? this first period of uh base 64 that's just going to be algorithm it's signed with HS 256 and then the body which is going to be after the period right here that's just going to be all this information I'm guessing we probably want to change the ... | 486.8 | 0 | {

secure things around that, right? So if you can identify how they generate the UU ID and it's not random based, you may have a better way to brute force UIDs. | 541.68 | 0 | {

So, that's not an attack here. I just wanted to kind of highlight of something I would look at, right? We can see the different versions. I forget which one is vulnerable. Um, but yeah, some of them aren't random. They're just like based upon the time or something like that. And they can brute force it and then um get ... | 551.92 | 0 | {

um we don't have any like cookies here, no cookies here, but after this we start having cookies. So this indicates that the client has some way to generate their own cookie.

And if we look up here, we have the JWT secret right here. Secret key critical ops 2025. So this is going to allow us to forge our JWTs. And to do that, I'm going to install an extension of Burp Suite. If we um a lot of people don't really use JWTO, they would just do it all within Burp.

Let's see. The ones that have JWTs is going to be highlighted in green. It's also going to add the token here. Um I know my font size a bit big so it's not the most pretty thing to look at.

We can go to repeater, change the role to admin, and then sign it. And we have no signing keys have been added to the keys tab. So, I'm going to go to JDT editor, new symmetric key.

Um, I'd submit the report, try to get the money, but one of the things I think many people miss out on bug bounty is they try to do everything manually, right?
