Summary

The Rational Insight 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
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119158&gt; 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
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119157&gt; for the current score
CVSS Environmental Score*: Undefined
