Amazon Linux 2 : tomcat (ALASTOMCAT9-2024-011)

medium Nessus Plugin ID 190051

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of tomcat installed on the remote host is prior to 9.0.50-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2TOMCAT9-2024-011 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)

- Generation of Error Message Containing Sensitive Information vulnerability in Apache Tomcat.This issue affects Apache Tomcat: from 8.5.7 through 8.5.63, from 9.0.0-M11 through 9.0.43. Users are recommended to upgrade to version 8.5.64 onwards or 9.0.44 onwards, which contain a fix for the issue. (CVE-2024-21733)

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

Solution

Run 'yum update tomcat' to update your system.
