Cvss 3 Severity Score

Description

Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.68, 8.x before 8.0.31, and 9.x before 9.0.0.M2 does not place org.apache.catalina.manager.StatusManagerServlet on the org/apache/catalina/core/RestrictedServlets.properties list, which allows remote authenticated users to bypass intended SecurityManager restrictions and read arbitrary HTTP requests, and consequently discover session ID values, via a crafted web application.

From the Ubuntu Security Team

It was discovered that Tomcat did not place StatusManagerServlet on the RestrictedServlets list. A remote attacker could possibly use this issue to read arbitrary HTTP requests, including session ID values. This issue only affected Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 15.10.
