-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 CVE-2016-0714 Apache Tomcat Security Manager Bypass
Severity: Moderate Vendor: The Apache Software Foundation Versions Affected: - - Apache Tomcat 6.0.0 to 6.0.44 - - Apache Tomcat 7.0.0 to 7.0.67 - - Apache Tomcat 8.0.0.RC1 to 8.0.30 - - Apache Tomcat 9.0.0.M1 - - Earlier, unsupported Tomcat versions may be affected Description: Tomcat provides several session persistence mechanisms. The StandardManager persists session over a restart. The PersistentManager is able to persist sessions to files, a database or a custom Store. The Cluster implementation persists sessions to one or more additional nodes in the cluster. All of these mechanisms could be exploited to bypass a security manager. Session persistence is performed by Tomcat code with the permissions assigned to Tomcat internal code. By placing a carefully crafted object into a session, a malicious web application could trigger the execution of arbitrary code. Mitigation: Users of affected versions should apply one of the following mitigations - - Upgrade to Apache Tomcat 9.0.0.M3 or later (9.0.0.M2 has the fix but was not released) - - Upgrade to Apache Tomcat 8.0.32 or later (8.0.31 has the fix but was not released) - - Upgrade to Apache Tomcat 7.0.68 or later - - Upgrade to Apache Tomcat 6.0.45 or later Credit: This issue was discovered by The Apache Tomcat Security Team.
