Apache Tomcat 8.5.x < 8.5.34 Open Redirect Weakness

medium Nessus Network Monitor Plugin ID 700696


The remote Apache Tomcat server is affected by a open redirect vulnerability.


The version of Apache Tomcat installed on the remote host is version 8.5.x prior to 8.5.34. 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.


Upgrade to Apache Tomcat version 8.5.34 or later.
