Description
HAX CMS helps manage microsite universe with PHP or NodeJs backends. Prior to 25.0.0, the /server-status endpoint is publicly accessible and exposes sensitive information including authentication tokens (user_token), user activity, client IP addresses, and server configuration details. This allows any unauthenticated user to monitor real-time user interactions and gather internal infrastructure information. This vulnerability is fixed in 25.0.0.
Analysis
Information disclosure in HAX CMS versions prior to 25.0.0 exposes authentication tokens and user activity via unauthenticated access to the /server-status endpoint. Remote attackers can retrieve active user tokens, monitor real-time interactions, harvest client IP addresses, and map internal infrastructure without authentication (CVSS:4.0 AV:N/AC:L/PR:N). …

Remediation
Within 24 hours: Inventory all HAX CMS deployments and confirm versions; immediately restrict network access to the /server-status endpoint via firewall rules or WAF to allow only trusted administrative IPs. Within 7 days: Rotate all authentication tokens and session credentials for users whose tokens may have been exposed; enable detailed access logging on the /server-status endpoint to detect prior exploitation. …
