Summary
The remote Wu-FTPd server seems to be vulnerable to a remote privilege escalation.
Insight
Insight
This version contains a flaw that may allow a malicious user to gain access to unauthorized privileges. Specifically, there is a flaw in the way that the server handles an ABOR command after a data connection has been closed. The flaw is within the dologout() function and proper exploitation will give the remote attacker the ability to execute arbitrary code as the 'root' user.
Solution
Solution
Upgrade to Wu-FTPd 2.4.2 or newer.
