A high-severity authorization bypass in Revive Adserver allows authenticated users to perform unauthorized deletions of tracker data belonging to other accounts.

This is an authorization bypass vulnerability located in the tracker-delete.php script. It permits any authenticated user with standard tracker-deletion permissions to improperly access and delete tracker entities owned by other users or accounts.

The ability for a malicious or compromised user account to delete trackers belonging to others poses a significant risk to data integrity and operational continuity. Given the CVSS score of 7.1, this flaw is categorized as High severity because it facilitates unauthorized modification of application data, which could lead to service disruption or the loss of critical advertising metrics.

Immediate Action: Review the official Revive Adserver vendor security advisories and apply the latest security updates as soon as they are made available to resolve the authorization logic flaw.

Proactive Monitoring: Monitor application access logs for unusual patterns of deletions, particularly those involving tracker IDs not associated with the active user session.

Compensating Controls: If a patch is not immediately available, consider restricting access to the tracker management interface to trusted administrative personnel only, or implement Web Application Firewall rules to monitor requests directed at the tracker-delete.php endpoint.

Public Exploit Available: No (exploit_available: false)

This vulnerability represents a significant risk to the integrity of advertising data within the Revive Adserver environment. Organizations should prioritize patching as soon as the vendor releases a fix, as the flaw allows for unauthorized administrative actions that could severely impact business operations.
