high Nessus Network Monitor Plugin ID 700057
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 web server is missing an Apache Tomcat patch update.

Description

The version of Apache Tomcat installed on the remote host is version 7.0.x prior to 7.0.77, 8.0.x prior to 8.0.43, 8.5.x prior to 8.5.13, and 9.0.0.x prior to 9.0.0.M19, and is affected by multiple vulerabilities :

- An unspecified flaw exists in the pipelined request handling that is triggered when send file processing was used. This may result in responses being sent for different requests and may allow a remote attacker to disclose potentially sensitive information. (CVE-2017-5647)
- A flaw exists in the handling of HTTP/2 GOAWAY Frames that is triggered as streams associated with the connections are not properly closed. With specially crafted HTTP/2 requests, a remote attacker can exhaust available threads, resulting in a denial of service. (CVE-2017-5650)
- A flaw exists in the refactoring of HTTP connectors related to the processing of send files. This may cause the processor to be added to the processor cache twice, allowing a remote attacker to gain access to sensitive information from other sessions which use the processor for requests. (CVE-2017-5651)

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

Solution

Upgrade to Apache Tomcat version 8.5.13 / 9.0.0.M19 or later.
