It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2025-910 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)
