Description :
-------------
A local overflow exists in the session file used by KiTTY portable, in the HostName parameter. It is possible to write
an overly long string to trigger an overflow. It can be used to trigger code execution on Windows XP SP3, or to crash
the program from Windows 7 to Windows 10. It has been tested with KiTTY portable 0.65.0.2p/0.65.0.3p/0.65.1.1p, but earlier versions are
likely to be vulnerable too.
WinXP -> Local Code Execution
Win7 -> Denial Of Service
Win8.1 -> Denial Of Service
Win10 -> Denial Of Service
Instructions:
-------------
- Run exploit
- Launch KiTTY, select "EvilSession" on the session list, then click "Load".
Exploitation:
-------------
When writing a 1500 bytes string to the HostName parameter in a session file, EIP is overwritten at offset 1232.
As ESP points to our buffer, we use an address doing a JMP ESP in an unprotected DLL. However, as the memory area
we land in is not reliable for bigger shellcode such as reverse shell, using an egg hunter is required. The final
shellcode is written into another session parameter, LogFileName. After successful exploitation, a reverse shell
is given if this payload has been selected on Windows XP SP3 (on Windows 7/8.1/10, KiTTY crashes):
