Session fixation still possible with disableURLRewriting enabled (CVE-2014-0033)

Original Release Date: May 1, 2014
Last Revised: October 26, 2017
Number: ASA-2014-125
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.

Previous fixes to path parameter handling introduced a regression that meant session IDs provided in the URL were considered even when disableURLRewriting was configured to true. Note that the session is only used for that single request. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-0033 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-2014-0033
The risk is rated Low for AES, Experience Portal, Messaging, Presence Services, System Platform and Utility Services because the exploit cannot be performed without non-standard direct user interaction.
The risk is rated None for all other products because the affected versions of tomcat are not installed by default.

3. Avaya Software-Only Products:

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.

Product: Actions:
Avaya Aura® Application Enablement Services See recommended actions below.
Avaya Aura® Experience Portal See recommended actions below.
Avaya Aura® Presence Services See recommended actions below.
Avaya Secure Access Link Gateway See recommended actions below.
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.
