"The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2741
advisory.

  - In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input
    string, like //../foo, or \\..\foo, the result would be the same value, thus possibly providing access
    to files in the parent directory, but not further above (thus limited path traversal), if the calling
    code would use the result to construct a path value. (CVE-2021-29425)

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