Rhinosoft · Serv-U Ftp Server · CVE-2004-1675
**Name of the Vulnerable Software and Affected Versions**
Serv-U FTP server versions 4.x through 5.x
**Description**
The issue allows remote attackers to cause a denial of service, resulting in an application crash. This can be achieved by sending a STORE UNIQUE (STOU) command with specific MS-DOS device name arguments, such as `COM1`, `LPT1`, `PRN`, or `AUX`.
**Recommendations**
For Serv-U FTP server versions 4.x through 5.x, consider disabling the STORE UNIQUE (STOU) command as a temporary workaround until a patch is available. Restrict access to the server to minimize the risk of exploitation.
