Description
An exploitable privilege escalation vulnerability exists in the Shimo VPN 4.1.5.1 helper service in the writeConfig functionality. A non-root user is able to write a file anywhere on the system. 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 exploit it successfully.
