Summary

Red Hat Security Advisory: apache-commons-vfs security update

Severity

Moderate

Notes

Topic: An update for apache-commons-vfs is now available for Red Hat Enterprise Linux 7 Extended Lifecycle Support. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details: 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.

CVE-2025-27553

A flaw was found in Apache Commons VFS. 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, such as "%2E%2Ebar.txt", it might return file objects that are not a descendent of the base file without throwing an exception.

5.3 (Medium)

CVE-2025-27553 (GCVE-0-2025-27553)

Vulnerability from cvelistv5 – Published: 2025-03-23 14:16 – Updated: 2025-04-02 22:03

Title

Apache Commons VFS: Possible path traversal issue when using NameScope.DESCENDENT

Summary

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.

Severity

7.5 (High)
