Security Bulletin: Security vulnerabilities in Apache Tomcat affects multiple IBM Rational products based on IBM's Jazz technology

Summary

The Jazz Team Server is shipped with or supports versions of the Apache Tomcat web server which contain security vulnerabilities that could potentially impact the following IBM Rational products deployed on Apache Tomcat: Collaborative Lifecycle Management (CLM), 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

CVEID: CVE-2016-6816**
DESCRIPTION:** Apache Tomcat is vulnerable to HTTP response splitting attacks, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability to inject arbitrary HTTP headers and cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting, and possibly obtain sensitive information.
CVSS Base Score: 6.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/119158 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)

CVEID: CVE-2016-8735**
DESCRIPTION:** Apache Tomcat could allow a remote attacker to execute arbitrary code on the system, caused by an error in the JmxRemoteLifecycleListener. By sending specially crafted data to a JMX port, an attacker could exploit this vulnerability to execute arbitrary code on the system with elevated privileges.
CVSS Base Score: 7.3
