Apache Tomcat 10.0.0.M1 < 10.0.0.M8

medium Nessus Plugin ID 150935

Language:

Synopsis

The remote Apache Tomcat server is affected by a vulnerability

Description

The version of Tomcat installed on the remote host is prior to 10.0.0.M8. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_10.0.0-m8_security-10 advisory.

- If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to 8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

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 10.0.0.M8 or later.
