WU-FTPD ABOR Command Arbitrary File Access
Medium Nessus Plugin ID 14301
SynopsisThe remote FTP server seems to be vulnerable to a remote privilege escalation.
DescriptionThe version of WU-FTPD running on the remote host 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.
This flaw may lead to a loss of confidentiality and/or integrity.
*** Nessus solely relied on the banner of the remote server
*** to issue this warning, so it may be a false positive.
SolutionUpgrade to Wu-FTPd 2.4.2 or newer
