Apache Tomcat 7.0.x < 7.0.28 Multiple DoS

medium Nessus Plugin ID 62985
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 remote denial of service vulnerabilities.

Description

According to its self-reported version number, the instance of Apache Tomcat 7.0 listening on the remote host is prior to 7.0.28. It is, therefore, affected by the following vulnerabilities :

- A flaw exists within the parseHeaders() function that allows an attacker, via a crafted header, to cause a remote denial of service. (CVE-2012-2733)

- An error exists related to the 'NIO' connector when HTTPS and 'sendfile' are enabled that can force the application into an infinite loop. (CVE-2012-4534)

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

Solution

Upgrade to Apache Tomcat version 7.0.28 or later.
