Fedora Repository: Relative Path Traversal
CVE-2025-23011 is a high-severity relative path traversal vulnerability in Fedora Repository, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected Fedora Repository versions: 3.8.1 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.76% chance of exploitation within 30 days, higher than 56% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Fcrepo to 6.5.1 or a later version.

Official description
Fedora Repository 3.8.1 allows path traversal when extracting uploaded archives ("Zip Slip"). A remote, authenticated attacker can upload a specially crafted archive that will extract an arbitrary JSP file to a location that can be executed by an unauthenticated GET request. Fedora Repository 3.8.1 was released on 2015-06-11 and is no longer maintained. Migrate to a currently supported version (6.5.1 as of 2025-01-23).

The underlying weakness: Relative Path Traversal
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as.. that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: poc, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
