RHEL 6 : tomcat6 (RHSA-2013:0158)

medium Nessus Plugin ID 78944

Language:

Synopsis

The remote Red Hat host is missing a security update for tomcat6.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:0158 advisory.

Apache Tomcat is a servlet container.

It was found that when an application used FORM authentication, along with another component that calls request.setUserPrincipal() before the call to FormAuthenticator#authenticate() (such as the Single-Sign-On valve), it was possible to bypass the security constraint checks in the FORM authenticator by appending /j_security_check to the end of a URL. A remote attacker with an authenticated session on an affected application could use this flaw to circumvent authorization controls, and thereby access resources not permitted by the roles associated with their authenticated session.
(CVE-2012-3546)

Warning: Before applying the update, back up your existing JBoss Enterprise Web Server installation (including all applications and configuration files).

Users of Tomcat should upgrade to these updated packages, which resolve this issue. Tomcat must be restarted for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL tomcat6 package based on the guidance in RHSA-2013:0158.
