Subject: CVE-2012-3546 Apache Tomcat Bypass of security
	constraints

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

CVE-2012-3546 Apache Tomcat Bypass of security constraints

Severity: Important

Vendor: The Apache Software Foundation

Versions Affected:
- - Tomcat 7.0.0 to 7.0.29
- - Tomcat 6.0.0 to 6.0.35
Earlier unsupported versions may also be affected

Description:
When using FORM authentication it was possible to bypass the security
constraint checks in the FORM authenticator by appending
"/j_security_check" to the end of the URL if some other component (such
as the Single-Sign-On valve) had called request.setUserPrincipal()
before the call to FormAuthenticator#authenticate().

Mitigation:
Users of affected versions should apply one of the following mitigations:
- - Tomcat 7.0.x users should upgrade to 7.0.30 or later
- - Tomcat 6.0.x users should upgrade to 6.0.36 or later

This issue was identified by The Tomcat security team
