CVE-2018-1304

tomcat: Incorrect handling of empty string URL in security constraints can lead to unintended exposure of resources

Published Feb 28, 2018 CVSS 3.0 · 5.9 Medium EPSS 17.1% KEV · Not listed
Description
The URL pattern of "" (the empty string) which exactly maps to the context root was not correctly handled 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 when used as part of a security constraint definition. This caused the constraint to be ignored. It was, therefore, possible for unauthorised users to gain access to web application resources that should have been protected. Only security constraints with a URL pattern of the empty string were affected.
