PDF Complete Corporate Edition – Unquoted Service Path Privilege Escalation

PDF Complete Corporate Edition installs a service with an unquoted service path, which enables a local privilege escalation vulnerability. To exploit this vulnerability, a local attacker can insert an executable file in the path of the service. Rebooting the system or restarting the service will run the malicious executable with elevated privileges.

Mitigation:

Ensure that all services have quoted service paths.
