Executive Summary

This vulnerability is a Server-Side Request Forgery (SSRF) protection bypass in Directus, a real-time API and app dashboard for managing SQL database content. Before version 11.16.0, the mechanism that validated IP addresses to block requests to local and private networks could be circumvented by using IPv4-Mapped IPv6 address notation. This allowed attackers to bypass the IP address validation and potentially make unauthorized requests.

Impact Analysis

The vulnerability allows an attacker to bypass IP address validation and send unauthorized requests to internal or private network resources through the Directus server. This can lead to unauthorized access to sensitive internal services or data, potentially compromising confidentiality. According to the CVSS score, the impact on confidentiality is high, while integrity and availability are not affected.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade Directus to version 11.16.0 or later, where the SSRF protection bypass has been fixed.
