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.


Apache Tomcat 8.5.x < 8.5.16 Multiple Vulnerabilities


The version of Apache Tomcat installed on the remote host is 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 the scanner has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.


Upgrade to Apache Tomcat version 8.5.16 or later.
