Apache Tomcat is an open source software implementation for Java Servlet and JavaServer Pages (JSP) technologies.
FORM authentication associates the most recent request requiring authentication with the current session. By repeatedly sending a request for an authenticated resource while the victim is completing the login form, an attacker could inject a request that would be executed using the victim's credentials. This attack has been prevented by changing the session ID prior to displaying the login page as well as after the user has successfully authenticated.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-2067 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.
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:
||The risk is None for CS1000, IP Office, IP Office Application Server, Session Manager and System Manager because the affected versions of tomcat (6.0.21 - 6.0.36) are not installed.
The risk is None for SAL Gateway because its web interface does not use FORM authentication.
The risk is Medium for other products because the exploit could lead to compromise of confidentiality, integrity or availability of resources by an unauthenticated user.
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the applications installed on the system which may threaten the integrity of the underlying platform.

|Avaya Voice Portal||See recommended actions below.|
Recommended Actions for Software-Only Products:
If the affected package is installed, Avaya recommends customers determine if Apache Tomcat is installed by the Avaya software-only product or as a separate application and follow the vendor's guidance.
