d34bef0b-f312-11eb-b12b-fc4dd43e2b6atomcat -- HTTP request smuggling in multiple versions

Bahruz Jabiyev, Steven Sprecher and Kaan Onarlioglu of NEU seclab reports:

Apache Tomcat did 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. Specifically: Tomcat incorrectly ignored the transfer-encoding header if the client declared it would only accept an HTTP/1.0 response; Tomcat honoured the identify encoding; and Tomcat did not ensure that, if present, the chunked encoding was the final encoding.

6a72eff7-ccd6-11ea-9172-4c72b94353b5Apache Tomcat -- Multiple Vulnerabilities

The Apache Software Foundation reports:

An h2c direct connection did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service.

The payload length in a WebSocket frame was not correctly validated. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service.

A specially crafted sequence of HTTP/2 requests could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive.

8b571fb2-f311-11eb-b12b-fc4dd43e2b6atomcat -- JNDI Realm Authentication Weakness in multiple versions

ilja.farber reports:

Queries made by the JNDI Realm did not always correctly escape parameters. Parameter values could be sourced from user provided data (eg 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.
