Apache Tomcat 8.5.0 < 8.5.68

medium Nessus Plugin ID 152183

Synopsis

The remote Apache Tomcat server is affected by a vulnerability

Description

The version of Tomcat installed on the remote host is prior to 8.5.68. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_8.5.68_security-8 advisory.

- Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding;
and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
(CVE-2021-33037)

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 8.5.68 or later.
