Summary
The Jazz Team Server is shipped with a version of the Apache Tomcat web server
which contains security vulnerabilities that could potentially impact the
following IBM Rational products deployed on Apache Tomcat: Collaborative
Lifecycle Management (CLM), Rational Requirements Composer (RRC), Rational
DOORS Next Generation (RDNG), Rational Engineering Lifecycle Manager (RELM),
Rhapsody Design Manager (Rhapsody DM), Rational Software Architect Design
Manager (RSA DM), Rational Team Concert (RTC), and Rational Quality Manager
(RQM).
Vulnerability Details
IBM Jazz Team Server applications are shipped with an Apache Tomcat web
server. Apache Tomcat released new versions which contain security
vulnerability fixes.
IBM Jazz Team Server may be deployed on either IBM WebSphere Application
Server (WAS) or Apache Tomcat. These vulnerabilities are for deployments
deployed on Apache Tomcat only. Deployments using WAS are not vulnerable.
CVEID: CVE-2014-0227
DESCRIPTION: Apache Tomcat is vulnerable to HTTP request smuggling. A remote
attacker could send a specially-crafted request in a malformed chunked header
to the Web server to cause multiple processing conflicts on the servers. An
attacker could exploit this vulnerability to poison the web cache, bypass web
application firewall protection, and conduct XSS attacks.
