Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2025-911 advisory.

 Path Equivalence: 'file.Name' (Internal Dot) leading to Remote Code Execution and/or Information disclosure and/or malicious content added to uploaded files via write enabled Default Servlet in Apache Tomcat.

 This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.2, from 10.1.0-M1 through 10.1.34, from 9.0.0.M1 through 9.0.98.

 If all of the following were true, a malicious user was able to view security sensitive files and/or inject content into those files:- writes enabled for the default servlet (disabled by default)- support for partial PUT (enabled by default)- a target URL for security sensitive uploads that was a sub-directory of a target URL for public uploads- attacker knowledge of the names of security sensitive files being uploaded- the security sensitive files also being uploaded via partial PUT

 If all of the following were true, a malicious user was able to perform remote code execution:- writes enabled for the default servlet (disabled by default)- support for partial PUT (enabled by default)- application was using Tomcat's file based session persistence with the default storage location- application included a library that may be leveraged in a deserialization attack

 Users are recommended to upgrade to version 11.0.3, 10.1.35 or 9.0.98, which fixes the issue.

 More justification and the patch links are available for all versions here:[1] https://tomcat.apache.org/security-11.html[2] https://tomcat.apache.org/security-10.html[3] https://tomcat.apache.org/security-9.html (CVE-2025-24813)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'dnf update tomcat9 --releasever 2023.7.20250331' to update your system.
