Description

ePO runs on Apache Tomcat, and as per CVEs listed above, the Tomcat update consumed by ePO is possibly vulnerable to remote code execution.

This ePO update resolves the following issues:
 
CVE-2017-12615
When running Tomcat with HTTP PUTs enabled (for example via setting the readonly initialization parameter of the Default servlet to false), it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council’s effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, visit the CVSS website at: http://www.first.org/cvss/.

When calculating CVSS scores, McAfee has adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We do not factor into a score any potential follow-on exploits that might be made possible by successful exploitation of the issue being scored
 
What are the CVSS scoring metrics that have been used?
