AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability in ZITADEL (versions 4.7.0 and below) is an unauthenticated Server-Side Request Forgery (SSRF) that allows an attacker to make the server send HTTP requests to arbitrary domains, including internal network addresses. It exploits the x-zitadel-forward-host header, which the ZITADEL Login UI (V2) trusts as a fallback, enabling attackers to read responses from these requests without authentication.
How can this vulnerability impact me? :
The vulnerability can allow an attacker to exfiltrate data by forcing the server to access and read responses from arbitrary internal or external domains. It can bypass network segmentation controls, potentially exposing sensitive internal resources and data to unauthorized parties.
What immediate steps should I take to mitigate this vulnerability?
Upgrade ZITADEL to version 4.7.1 or later, as this version contains the fix for the unauthenticated full-read SSRF vulnerability.
