Apache Tomcat 7.0.x < 7.0.100 Multiple Vulnerabilities

critical Web Application Scanning Plugin ID 98948
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 7.0.x < 7.0.100 Multiple Vulnerabilities


The version of Apache Tomcat installed on the remote host is 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 or 7.0.0 to 7.0.99. It is, therefore, affected by multiple vulnerabilities :

- An arbitrary file read vulnerability in AJP protocol due to an implementation defect which could also be leveraged to achieve remote code execution.

- A HTTP request smuggling vulnerability due to some invalid HTTP headers parsed as valid.

- A HTTP request smuggling vulnerability due to invalid Transfer-Encoding headers incorrectly processed.

Note that the scanner has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.


Upgrade to Apache Tomcat version 7.0.100 or later.
