The remote host is vulnerable to a remote 'format string' flaw.
The remote host is running WarFTPd, an FTP server for the Microsoft platform. The version of WarFTPd running on this host contains multiple 'format string' vulnerabilities. An attacker exploiting these flaws would need to be able to authenticate to the FTP server. After authentication, the attacker would send a malformed request. Successful exploitation would allow the attacker to crash the application and possibly execute arbitrary code on the remote server. The vulnerable commands are 'CWD', 'CDUP', 'DELE', 'NLST', 'LIST' and 'SIZE'.
Upgrade to version 1.82.00-RC13 or higher.
