Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: apache-commons-vfs (UTSA-2025-984774)

high Nessus Plugin ID 267636

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-984774 advisory.

Relative Path Traversal vulnerability in Apache Commons VFS before 2.10.0.

The FileObject API in Commons VFS has a 'resolveFile' method that takes a 'scope' parameter. Specifying 'NameScope.DESCENDENT' promises that an exception is thrown if the resolved file is not a descendent of the base file. However, when the path contains encoded ..
characters (for example, %2E%2E/bar.txt), it might return file objects that are not a descendent of the base file, without throwing an exception.
This issue affects Apache Commons VFS: before 2.10.0.

Users are recommended to upgrade to version 2.10.0, which fixes the issue.

Tenable has extracted the preceding description block directly from the Unity 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.

Solution

Update the affected apache-commons-vfs package.
