Overview

org.apache.tomcat:tomcat is an implementation of the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies.

Affected versions of this package are vulnerable to Improper Input Validation. Queries made by the JNDI Realm did not always correctly escape parameters. Parameter values could be sourced from user provided data (e.g., user names) as well as configuration data provided by an administrator. In limited circumstances it was possible for users to authenticate using variations of their user name and/or to bypass some of the protection provided by the LockOut Realm.
