Executive Summary

This is an Insecure Direct Object Reference (IDOR) vulnerability in the NextGEN Gallery WordPress plugin before version 4.5.0. It allows authenticated users with gallery-management capabilities to modify settings of any gallery on the site, including those owned by others. The flaw occurs because the plugin does not verify if the user saving a gallery owns it.

Detection Guidance

Check the installed version of the NextGEN Gallery plugin. If it is below 4.5.0, the system is vulnerable. Use WordPress admin panel or run a command like 'wp plugin list' in the WordPress directory to verify the version.

Impact Analysis

An attacker with gallery-management access could overwrite gallery settings, including changing the filesystem path. This could lead to unauthorized access to or deletion of gallery files, data corruption, or potential further attacks on the WordPress site.

Compliance Impact

This vulnerability could lead to unauthorized access or modification of sensitive data stored in galleries, potentially violating GDPR (data protection) or HIPAA (health data privacy) requirements. Unauthorized changes to filesystem paths may also compromise data integrity.

Mitigation Strategies

Update the NextGEN Gallery plugin to version 4.5.0 or later immediately. Remove or restrict gallery-management capabilities from untrusted users until the update is applied.
