Assigner: WPScan

Description
The Photo Gallery, Sliders, Proofing and WordPress plugin before 4.5.0 does not verify that the requesting user is entitled to a given image record before returning it, allowing users with the Contributor role and above to read the stored metadata of any image on the site, including images in galleries belonging to other users. The disclosed data includes the image's stored EXIF subset, covering camera make and model and capture timestamp, along with internal checksums and identifiers that the Photo Gallery, Sliders, Proofing and WordPress plugin before 4.5.0's own capability-gated read path reserves to administrators.

Executive Summary

This is an Insecure Direct Object Reference (IDOR) vulnerability in the NextGEN Gallery WordPress plugin before version 4.5.0. It allows users with the Contributor role or higher to access metadata of any image on the site, including images in other users' galleries. The exposed metadata includes EXIF data like camera make, model, capture timestamp, internal checksums, and identifiers that are normally restricted to administrators.

Detection Guidance

Check if your WordPress site uses the NextGEN Gallery plugin version prior to 4.5.0. Log in as a Contributor role user and attempt to access image metadata via plugin endpoints. Verify if unauthorized access to EXIF data or other restricted fields is possible.

Impact Analysis

If you use the NextGEN Gallery plugin before version 4.5.0, an attacker with a Contributor role or higher could access sensitive image metadata from other users' galleries. This could lead to privacy breaches, unauthorized data exposure, or potential misuse of internal identifiers and checksums.

Compliance Impact

This vulnerability could impact compliance with GDPR and HIPAA by exposing personal or sensitive data through image metadata. GDPR requires protecting personal data, and HIPAA mandates safeguarding health-related information. Unauthorized access to such metadata may violate these regulations.

Mitigation Strategies

Update the NextGEN Gallery plugin to version 4.5.0 or later immediately. Review user roles and permissions to ensure Contributors do not have unnecessary access to sensitive data. Monitor for any unusual access patterns to image metadata.
