org/apache/catalina/core/DefaultInstanceManager.java in Apache Tomcat 7.x before 7.0.22 does not properly restrict ContainerServlets in the Manager application, which allows local users to gain privileges by using an untrusted web application to access the Manager application's functionality.

Security readout for executives and security teams

This issue affects old Apache Tomcat 7 releases before 7.0.22. A user who can place or run an untrusted web application on the same Tomcat instance could reach Manager application functions that should have been restricted, potentially increasing their privileges. Exposure is most likely in legacy environments still running Tomcat 7.x before 7.0.22, especially shared or delegated hosting where untrusted applications can be deployed alongside the Manager application. Treat as a targeted legacy-platform risk. Prioritize systems where multiple teams, customers, or untrusted code share one Tomcat instance with Manager installed. Mitigation focus: Upgrade Apache Tomcat 7.x to 7.0.22 or later.; Review Apache Tomcat 7 security guidance for vendor-confirmed remediation.; Remove or restrict Manager application access where it is not operationally required..
