RHSA-2013:0005 - Important: tomcat6 security update

Synopsis

Important: tomcat6 security update

Type/Severity

Security Advisory Important

Topic

Updated tomcat6 packages that fix one security issue are now available for JBoss Enterprise Web Server 2.0.0 for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Description

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.
