"The version of Tomcat installed on the remote host is prior to 9.0.99. It is, therefore, affected by a vulnerability as
referenced in the fixed_in_apache_tomcat_9.0.99_security-9 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 9.0.99, which fixes the issue. (CVE-2025-24813)

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