'Name' => 'HP SiteScope DNS Tool Command Injection',
'Description' => %q{
This module exploits a command injection vulnerability
discovered in HP SiteScope 11.30 and earlier versions (tested in 11.26
and 11.30). The vulnerability exists in the DNS Tool allowing an
attacker to execute arbitrary commands in the context of the service. By
default, HP SiteScope installs and runs as SYSTEM in Windows and does
not require authentication. This vulnerability only exists on the
Windows version. The Linux version is unaffected.
