Apache Tomcat 8.5.0 < 8.5.57 Multiple Vulnerabilities

high Nessus Plugin ID 138574

Language:

Synopsis

The remote Apache Tomcat server is affected by multiple vulnerabilities

Description

The version of Tomcat installed on the remote host is 8.5.x prior to 8.5.57. It is, therefore, affected by multiple vulnerabilities as referenced in the Fixed in Apache Tomcat 8.5.57 security advisory.

- The payload length in a WebSocket frame was not correctly validated. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service (DoS).
(CVE-2020-13935)

- An h2c direct connection did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service (DoS). (CVE-2020-13934)

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

Solution

Upgrade to Apache Tomcat version 8.5.57 or later.
