TencentOS Server 2: apache-commons-vfs (TSSA-2025:0598)

high Nessus Plugin ID 276025

Synopsis

The remote TencentOS Server 2 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2025:0598 advisory.

Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

CVE-2025-27553:
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 Tencent 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 packages.
