- The remote host seems to be running cvstrac,

- 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.
