| Detailed Description |
The WU-FTPD server, according to its version number, has a privilege escalation vulnerability via the ABOR command. WU-FTPD is an ftp server based on the BSD ftpd that is maintained by Washington University. WU-FTPD versions 2.4.1 and earlier contain a flaw that may allow a remote authenticated attacker to gain access to unauthorized privileges. This flaw can be exploited when an ftp client is transferring a file, then closes the connection and sends an ABOR command, which causes the server to execute the dologout() function, allowing the attacker to gain root privileges.
* Note: This check solely relied on the version number of the remote WU-FTP server to assess this vulnerability, so this might be a false positive.
