The remote host seems to be running cvstrac, a web-based bug and patch-set tracking system for CVS. This version of filediff has a flaw in the input sanitation which, when exploited, can lead to a remote attacker executing arbitrary commands on the system. ***** OVS has determined the vulnerability exists on the target ***** simply by looking at the version number(s) of CVSTrac ***** installed there.

Update to version 1.1.4 or disable this CGI suite
