Improper Authentication
A vulnerability in the JNDI Realm of Apache Tomcat allows an attacker to authenticate using variations of a valid user name and/or to bypass some of the protection provided by the `LockOut Realm`.
Inconsistent Interpretation of HTTP Requests (HTTP Request Smuggling)
Apache Tomcat does not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy.
