Panda Internet Security installs a service called 'panda_url_filtering'
with an unquoted service path running with SYSTEM privileges.
This could potentially allow an authorized but non-privileged local user
to execute arbitrary code with elevated privileges on the system.

====Proof-of-Concept====
To properly exploit this vulnerability, the local attacker must insert
an executable file in the path of the service. Upon service restart or
system reboot, the malicious code will be run with elevated privileges.
