    Package        : tomcat10
    CVE ID         : CVE-2025-24813

    A security vulnerability was found in Tomcat 10, a Java based web server and
    servlet engine. A malicious user was able to view security sensitive files
    and/or inject content into those files when writes were enabled for the default
    servlet (disabled by default) and support for partial PUT was enabled
    (default). Under certain circumstances, depending on the application in use,
    remote code execution may have been possible.

    For the stable distribution (bookworm), this problem has been fixed in
    version 10.1.34-0+deb12u2.

    We recommend that you upgrade your tomcat10 packages.

    For the detailed security status of tomcat10 please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/tomcat10

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

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