"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2025:10548 advisory.

    Commons VFS provides a single API for accessing various different file systems. It presents a uniform view
    of the files from various different sources, such as the files on local disk, on an HTTP server, or inside
    a Zip archive. Some of the features of Commons VFS are:
    * A single consistent API for accessing files of different
     types.
    * Support for numerous file system types.
    * Caching of file information. Caches information in-JVM,
     and optionally can cache remote file information on the
     local file system.
    * Event delivery.
    * Support for logical file systems made up of files from
     various different file systems.
    * Utilities for integrating Commons VFS into applications,
     such as a VFS-aware ClassLoader and URLStreamHandlerFactory.
    * A set of VFS-enabled Ant tasks.

    Security Fix(es):

    * apache-commons-vfs: Apache Commons VFS: Possible path traversal issue when using NameScope.DESCENDENT
    (CVE-2025-27553)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and
    other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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