Nagios 'statuswml.cgi' Remote Arbitrary Shell Command Injection Vulnerability

Summary
Nagios is prone to a remote command-injection vulnerability because it fails to adequately sanitize user-supplied input data. Remote attackers can exploit this issue to execute arbitrary shell commands with the privileges of the user running the application. Note that for an exploit to succeed, access to the WAP interface's ping feature must be allowed. Versions prior to Nagios 3.1.1 are vulnerable.
Solution
The vendor has released updates. Please see http://www.nagios.org/ for more information.
