tomcat: Apache Tomcat: Improper Authorization Allows Security Constraint Bypass

A flaw was found in Apache Tomcat where access control rules for the default servlet are improperly handled. An attacker can exploit this issue to bypass specific HTTP method restrictions, potentially gaining unauthorized access to protected application resources...

tomcat: Apache Tomcat: Denial of Service due to uncontrolled resource allocation

In Apache Tomcat, no limit was enforced on the request body for WebDAV LOCK or PROPFIND requests which were available to unauthenticated users. This allows a remote attacker to consume excessive resources, leading to Denial of Service DoS, making the affected system unavailable to legitimate user...
