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)

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
