The remote host seems to be running cvstrac, 
a web-based bug and patch-set tracking system for CVS.

This version contains multiple flaws in the mprintf, vmprintf, 
and vxprintf functions in cgi.c .  A remote attacker, exploiting
this flaw, would be able to execute arbitrary code on the 
remote 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
Risk factor : High";
