Security Bulletin: Security vulnerabilities in Apache Tomcat affect Rational Reporting for Development Intelligence (CVE-2016-6816, CVE-2016-8735)

Summary

The Rational Reporting for Development Intelligence (RRDI) is shipped with a version of the Apache Tomcat web server which contains security vulnerabilities that could have a potential security impact.

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

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.
