Detailsinfo

A vulnerability was found in Apache Tomcat up to 7.0.84/8.0.49/8.5.27/9.0.4 (Application Server Software) and classified as critical. This issue affects some unknown processing of the component URL Pattern Handler. The manipulation as part of a Empty String leads to a 7pk security vulnerability. Using CWE to declare the problem leads to CWE-254. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.
