Apache Tomcat 8.5.x < 8.5.16 Multiple Vulnerabilities

medium Nessus Network Monitor Plugin ID 700691
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Apache Tomcat server is affected by multiple vulnerabilities.

Description

The version of Apache Tomcat installed on the remote host is version 8.5.x prior to 8.5.16. It is, therefore, affected by multiple vulnerabilities :

- A flaw exists in the CORS filter because the HTTP Vary header was not properly added. This allows a remote attacker to conduct client-side and server-side cache poisoning attacks. (CVE-2017-7674)
- A flaw exists in the HTTP/2 implementation that bypasses a number of security checks that prevented directory traversal attacks. A remote attacker can exploit this to bypass security constraints. (CVE-2017-7675)

Note that Nessus Network Monitor has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat version 8.5.16 or later.
