This host is running CUPS (Common UNIX Printing System) Service, which is prone to Denial of Service Vulnerability.
Successful exploitation causes Denial of Service condition. Impact Level: Application
Upgrade to CUPS Version 1.3.8 or later. http://www.cups.org/software.php
The flaw is due to error in web interface (cgi-bin/admin.c), which uses the guest username when a user is not logged on to the web server. This leads to CSRF attacks with the add/cancel RSS subscription functions.
CUPS Versions prior to 1.3.8 on Linux.
