Description

The vulnerability allows a local attacker to bypass security manager restriction.

A local attacker, who controls web application, can abuse functionality of StandardManager and PersistentManager to gain control over sessions persistence, stored in files, in database or in custom Sore. Since session persistence is performed by Tomcat code with the permissions assigned to Tomcat internal code, the attacker can place specially crafted object into a session and execute arbitrary code on vulnerable system with elevated privileges.

Successful exploitation of the vulnerability may allow a local attacker to gain elevated privileges on the system.

Mitigation
Install the latest version Apache Tomcat 6.0.45, 7.0.68, 8.0.32 or 9.0.0.M3
