Apache Tomcat 9.0.0.M1 < 9.0.81 multiple vulnerabilities

medium Nessus Plugin ID 182809

Synopsis

The remote Apache Tomcat server is affected by multiple vulnerabilities

Description

The version of Tomcat installed on the remote host is prior to 9.0.81. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_9.0.81_security-9 advisory.

 - Tomcat did not correctly parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy. (CVE-2023-45648)

 - Tomcat's HTTP/2 implementation was vulnerable to the rapid reset attack. The denial of service typically manifested as an OutOfMemoryError. (CVE-2023-44487)

 - Tomcat's internal fork of a Commons FileUpload included an unreleased, in progress refactoring that exposed a potential denial of service on Windows if a web application opened a stream for an uploaded file but failed to close the stream. The file would never be deleted from disk creating the possibility of an eventual denial of service due to the disk being full. (CVE-2023-42794)

 - When recycling various internal objects, including the request and the response, prior to re-use by the next request/response, an error could cause Tomcat to skip some parts of the recycling process leading to information leaking from the current request/response to the next. (CVE-2023-42795)

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

Solution

Upgrade to Apache Tomcat version 9.0.81 or later.
