This signature detects an attempt to exploit a denial of service condition in the Serv-U FTP daemon. By supplying a STOU request containing a MS-DOS device name, a client can cause the server to crash.
Serv-U FTP Server is reported prone to a denial of service vulnerability. This issue presents itself because the application fails to handle exceptional conditions. The vulnerability is a result of Serv-U FTP Server processing certain 'STOU' commands. All versions of Serv-U prior to 5.2.0.1 are reportedly affected by this vulnerability.
