Description

An exploitable privilege escalation vulnerability exists in the Shimo VPN 4.1.5.1 helper service in the RunVpncScript command. The command takes a user-supplied script argument and executes it under root context. A user with local access can use this vulnerability to raise their privileges to root. An attacker would need local access to the machine to successfully exploit this bug.
