EServ FTP bounce attack
|eserv-ftp-bounce (8021)||Medium Risk|
EServ is vulnerable to an FTP bounce attack that uses the PORT command. In an FTP bounce attack, the FTP client specifies an IP address that is different from its own, which causes the FTP server to make a connection and send data to another host on the network. This creates the appearance that the computer is being probed or attacked by the FTP server; when, in fact, it is the FTP client that is indirectly attacking it.
Upgrade to the latest version of EServ (2.98-beta or later), available from the EServ FTP site. See References.
