Apache Tomcat 7.0.x < 7.0.91 Security Bypass

Medium Nessus Network Monitor Plugin ID 700681


The remote web server is missing an Apache Tomcat patch update.


The version of Apache Tomcat installed on the remote host is version 7.x prior to 7.0.91. It is, therefore, affected by a vulnerability that could allow a remote attacker to bypass security restrictions, caused by a missing host name verification when using TLS with the WebSocket client. An attacker could exploit this vulnerability to bypass security constraints to access restricted resources.


Update to Apache Tomcat version 7.0.91 or later.
