Blind SSRF in WatchGuard Dimension Database Server

Executive Summary

This is a blind server-side request forgery (SSRF) vulnerability in WatchGuard Dimension Database Server Test configuration. An authenticated privileged attacker can misuse the database connection test feature to probe internal network hosts and infer reachability based on response timing. This allows internal network mapping and discovery of reachable services and IP ranges.

Detection Guidance

To detect this vulnerability, monitor network traffic for unusual database connection test requests originating from WatchGuard Dimension servers. Check for timing discrepancies in responses when probing internal hosts. Review logs for authenticated administrator actions involving the database test feature targeting internal IP ranges.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by enabling unauthorized network reconnaissance. An attacker could map internal network services and infrastructure, which may expose sensitive data or systems that should be isolated. GDPR requires protecting personal data and ensuring network security, while HIPAA mandates safeguarding protected health information. Unauthorized network mapping could violate these requirements by revealing internal systems or enabling further attacks.
