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.
***** Nessus has determined the vulnerability exists on the target
***** simply by looking at the version number(s) of CVSTrac
***** installed there.
Solution : Update to version 1.1.4 or disable this CGI suite
