A buffer overflow in the Ability Server may allow remote authenticated attackers to execute arbitrary code.
A lack of input validation in Ability Server's FTP STOR command may allow a buffer overflow to occur. A remote authenticated attacker may be able to exploit this vulnerability by supplying the Ability Server with a specially crafted FTP STOR command.
According to reports, Ability Server versions 2.34, 2.25. and 2.32 are vulnerable. However, other versions may also be affected.
A remote authenticated attacker may be able to execute arbitrary code with the privileges of the Ability Server process or cause a denial-of-service condition.
We are currently unaware of a practical solution to this problem.
