CVE-2012-3546 Apache Tomcat Bypass of security constraints

Original Release Date: February 6, 2013
Last Revised: September 26, 2017
Number: ASA-2013-041
Risk Level: Medium
Advisory Version: 8.0
Advisory Status: Final

1. Overview:

Apache Tomcat is an open source software implementation for Java Servlet and JavaServer Pages (JSP) technologies.

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(). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-3546 to this issue.

More information about this vulnerability can be found in the security advisory issued by Apache Tomcat:

Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place, risk to Avaya products and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as an Avaya provided product update or the recommended Avaya action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period, but customers should not modify the System Product operating system or application unless the change is approved by Avaya. Making changes that are not approved may void the Avaya product service contract.

Mitigating Factors:

When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:

Vulnerability Mitigating Factors
CVE-2012-3546
This is a low risk for Application Enablement Services, CS1000, Messaging, Messaging Application Server, Presence Services, Secure Access Link Gateway, Session Manager, and SIP Enablement Services as FORM authentication is not used.
This is a medium risk for Application Server 5300, Conferencing, Conferencing Standard Edition, Experience Portal, IP Office Server Edition, IP Office Application Server, IQ, Meeting Exchange, System Platform, Utility Services and Voice Portal due to the possibility of bypassing security constraints.
