"The remote host is running Greymatter, a web-based log and journal 
maintenance system implemented in Perl. 

The remote version of this software is vulnerable to an HTML injection
attack due to a lack of filtering on user-supplied input in the file
'gm-comments.cgi'.  An attacker may exploit this flaw to perform a
cross-site scripting attack against the remote host. 

This software may be affected by another HTML injection vulnerability
in the file 'gm-cplog.cgi' and to a password disclosure vulnerability
in the file 'gm-token.cgi'." );
