Amazon Linux AMI : tomcat8 (ALAS-2020-1473) (deprecated)

high Nessus Plugin ID 144462

Language:

Synopsis

This plugin has been deprecated.

Description

The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1473 advisory.

 - While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests. (CVE-2020-17527)

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

This plugin has been deprecated due to Amazon pulling the previously published advisory.
