Description of the vulnerability

The HP SiteScope product usually allows local users to access to DNS tools.

However, on Windows, an attacker can ask the resolution of "example.com & shell-command". In this case, as "&" is a command separator, the shell command is run with privileges of the SiteScope service (SYSTEM).

A local attacker can therefore use the DNS Tool of HP SiteScope, in order to escalate his privileges.
