Apache Tomcat information exposure vulnerability

Published Feb 23, 2018 · Updated Oct 15, 2026 · Assigned by apache

Vendor: Apache Software Foundation Product: Apache Tomcat Package: org.apache.tomcat.embed:tomcat-embed-core Package: tomcat7 Package: tomcat8 Ecosystem: Maven Ecosystem: Ubuntu

Description

Security constraints defined by annotations of Servlets in Apache Tomcat 9.0.0.M1 to 9.0.4, 8.5.0 to 8.5.27, 8.0.0.RC1 to 8.0.49 and 7.0.0 to 7.0.84 were only applied once a Servlet had been loaded. Because security constraints defined in this way apply to the URL pattern and any URLs below that point, it was possible - depending on the order Servlets were loaded - for some security constraints not to be applied. This could have exposed resources to users who were not authorised to access them.
