Is correct these hash? - mmm286 - 01-21-2018
Hi,
I'm trying to extract user and pass of a application for try to convince my boss to use https instead http. The application have a form that login with http server.
I'm trying to sniff traffic and capture data with wireshark to get user/pass authentication:
I see these in wireshark:
Code:
[1,"UserSession:IDL_Register",1,0,{"1":{"str":"david"},"2":{"str":"|GSR|WIN-56DQT3UEU2J|3740|1516566386|ChallengeSIDStr|2:5D2F8D5A0E07E4C3C4E97990E5CE2A7C452DEEDDA43D52BF99AD9F47735FC4D675A3F62FF4FC028679BC06E78EA1B34F91DF9C5214F4F9C60E6E4124FXXXXXXX"},"3":{"str":"CLIENTE"},"4":{"str":"user"},"5":{"str":"GUI"},"6":{"str":"9.0.18.000"},"7":{"i64":600}}]HTTP/1.1 200 OKSince the user I login is david (I know also the password), I understand than the code 5D2F8..... is the hash password. I've used hashid and it says me:
Code:
Possible Hashs:
[+] SHA-512
[+] WhirlpoolSo I use hashcat but I can't get nothing:
Code:

Just deploy a rouge web server and do an active mitm? Or show how sensible data leaks. Or steal the cookie and execute actions. Or fire your fucking stupid boss.

Is the json you posted the request or the response? If it's the request, and that is indeed a hash of the password, then the password is being hashed client-side and you simply need to read the javascript to figure out what it's doing. However, it looks like that hash isn't a password hash, but rather the session id.
Anyway, undeath is correct. The biggest threat to http is mitm, so you need to actually mitm the app to demonstrate that threat.

Thanks!
Maybe is a session id. The application connects to apache tomcat. I'm trying to filter by "http.request.method == POST", but I can't see hash pass :-(

Password hashing is typically done server-side, not client-side. Client-side hashing is uncommon. You should be seeing the plaintext password in transit.

Hehe, that last suggestion seems a little less doable.
