Amazon Linux AMI : tomcat7 (ALAS-2020-1472) (deprecated)

medium Nessus Plugin ID 144458

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-2020-1472 advisory.

 - In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely. (CVE-2020-1935)

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.
