RhinoSoft Serv-U FTP server is prone to a directory-traversal vulnerability because the application fails to sufficiently sanitize user-supplied input.
Exploiting this issue allows an attacker to write arbitrary files to locations outside of the application's current directory. This could help the attacker launch further attacks.
Serv-U FTP server 126.96.36.199 is vulnerable; other versions may also be affected.
