CVE-2016-0714 – tomcat: Security Manager bypass via persistence mechanisms

https://notcve.org/view.php?id=CVE-2016-0714

The session-persistence implementation in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.68, 8.x before 8.0.31, and 9.x before 9.0.0.M2 mishandles session attributes, which allows remote authenticated users to bypass intended SecurityManager restrictions and execute arbitrary code in a privileged context via a web application that places a crafted object in a session. La implementación de persistencia de sesión en Apache Tomcat 6.x en versiones anteriores a 6.0.45, 7.x en versiones anteriores a 7.0.68, 8.x en versiones anteriores a 8.0.31 y 9.x en versiones anteriores a 9.0.0.M2 no maneja correctamente atributos de sesión, lo que permite a usuarios remotos autenticados eludir las restricciones de SecurityManager previstas y ejecutar código arbitrario en un contexto privilegiado a través de una aplicación web que sitúa un objeto manipulado en una sesión. It was found that several Tomcat session persistence mechanisms could allow a remote, authenticated user to bypass intended SecurityManager restrictions and execute arbitrary code in a privileged context via a web application that placed a crafted object in a session. • http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00069.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00082.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00085.html http://marc.info/?l=bugtraq&m=145974991225029&w=2 http://rhn.redhat.com/errata/RHSA-2016-1089.html http://rhn.redhat.com/errata/RHSA-2016-2045.html http://rhn.redhat.com/errata/RHSA-2016 • CWE-264: Permissions, Privileges, and Access Controls CWE-290: Authentication Bypass by Spoofing •
