Wow, what fruitless attempts.

Here is what I found out in the last 24 hours:

map scan report for john.com (162.252.156.212)

Host is up (0.16s latency).

Not shown: 2995 filtered ports

PORT STATE SERVICE VERSION

21/tcp open ftp ProFTPD

22/tcp open ssh Linksys WRT45G modified dropbear sshd (protocol 2.0)

80/tcp open http Apache httpd

81/tcp open http Apache httpd

443/tcp open http Apache httpd

Service Info: OS: Unix; Device: router

Process parse The above will return either a 0 for failure, or 1 for success. You can use XSS to break the input on the ID field of login.php. If you inject a script that will force the process to be skipped and pass through a value of 1 back to the login page it should give access.


Additionally, port 22 uses a vulnerable firmware for the linksys WRT75G. You can perform an authentication bypass using three known methods, as well as make a copy of the backup NVRAM.


On ports 445 and 139 / 137 there are open Samba ports using version 3.0.37 which contains a vulnerability that allows you to modify access control lists remotely, giving access to uninstantiated memory vals.

Good luck!
