This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from apache. Update commons_vfs to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
