Apache Tomcat 8.5.0 < 8.5.50 Privilege Escalation Vulnerability

high Nessus Plugin ID 132418

Synopsis

The remote Apache Tomcat server is affected by a privilege escalation vulnerability

Description

The version of Tomcat installed on the remote host is prior to 8.5.50. It is, therefore, affected by a privilege escalation vulnerability as referenced in the 'Fixed in Apache Tomcat 8.5.50' advisory.

- When using FORM authentication there was a narrow window where an attacker could perform a session fixation attack. The window was considered too narrow for an exploit to be practical but, erring on the side of caution, this issue has been treated as a security vulnerability. (CVE-2019-17563)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat version 8.5.50 or later.
