CVE-2018-1304 Security constraints mapped to context root are ignored Severity: High
Vendor: The Apache Software Foundation Versions Affected: Apache Tomcat 9.0.0.M1 to 9.0.4 Apache Tomcat 8.5.0 to 8.5.27 Apache Tomcat 8.0.0.RC1 to 8.0.49 Apache Tomcat 7.0.0 to 7.0.84 Description: The URL pattern of "" (the empty string) which exactly maps to the context root was not correctly handled 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. Mitigation: Users of the affected versions should apply one of the following mitigations: - Review security constraints and confirm none use a URL patten of "" (the empty string) - Upgrade to Apache Tomcat 9.0.5 or later - Upgrade to Apache Tomcat 8.5.28 or later - Upgrade to Apache Tomcat 8.0.50 or later - Upgrade to Apache Tomcat 7.0.85 or later Credit: This issue was reported publicly as bug 62067 and the security implications identified by the Apache Tomcat Security Team.
