Apache Tomcat Information disclosure (CVE-2011-3375)

Original Release Date: March 16, 2012
Last Revised: March 19, 2013
Number: ASA-2012-115
Risk Level: Low
Advisory Version: 3.0
Advisory Status: Final

1. Overview:

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

For performance reasons, information parsed from a request is often cached in two places: the internal request object and the internal processor object. These objects are not recycled at exactly the same time. When certain errors occur that needed to be added to the access log, the access logging process triggers the re-population of the request object after it has been recycled. However, the request object was not recycled before being used for the next request. That lead to information leakage (e.g. remote IP address, HTTP headers) from the previous request to the next request. The issue was resolved be ensuring that the request and response objects were recycled after being re-populated to generate the necessary access log entries. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-3375 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-2011-3375
The risk is Low for Application Enablement Services and Experience Portal because of the limited value of information that could be leaked.
There is no risk for all other products because the only versions of Tomcat affected are 6.0.30 - 6.0.33 and 7.x before 7.0.22. These other products do not have an affected version of Tomcat installed.
