Ability Server 2.34 STOR Command Stack Buffer Overflow



This module exploits a stack-based buffer overflow in Ability Server 2.34. Ability Server fails to check input size when parsing 'STOR' and 'APPE' commands, which leads to a stack based buffer overflow. This plugin uses the 'STOR' command. The vulnerability has been confirmed on version 2.34 and has also been reported in version 2.25 and 2.32. Other versions may also be affected.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/windows/ftp/ability_server_stor
msf exploit(ability_server_stor) > show targets
msf exploit(ability_server_stor) > set TARGET < target-id >
msf exploit(ability_server_stor) > show options
    ...show and set options...
msf exploit(ability_server_stor) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
