Apache Tomcat 6.0.x < 6.0.35 Multiple Vulnerabilities

high Nessus Network Monitor Plugin ID 6332
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.


The remote web server is affected by a denial of service vulnerability.


According to its self-reported version number, the instance of Apache Tomcat 6.x listening on the remote host is prior to 6.0.35. It is, therefore, affected by multiple vulnerabilities:

- Specially crafted requests are incorrectly processed by Tomcat and can cause the server to allow injection of arbitrary AJP messages. This can lead to authentication bypass and disclosure of sensitive information. (CVE-2011-3190)

- An information disclosure vulnerability exists. Request information is cached in two objects and these objects are not recycled at the same time. Further requests can obtain sensitive information if certain error conditions occur. (CVE-2011-3375)

- Large numbers of crafted form parameters can cause excessive CPU consumption due to hash collisions. (CVE-2011-4858, CVE-2012-0022)

Note that Nessus Network Monitor has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade to Apache Tomcat 6.0.35 or later.
