GHSA-MMJ8-WCVW-6789
Vulnerability from github – Published: 2026-06-26 21:50 – Updated: 2026-06-26 21:50Summary
The administrative proxy route (cmsproxy) in Aimeos Pagible CMS is vulnerable to a Server-Side Request Forgery (SSRF) attack via DNS Rebinding. A Time-of-Check to Time-of-Use (TOCTOU) race condition exists between the URL validation phase and the actual HTTP request phase, allowing attackers to access internal network resources and cloud metadata endpoints.
Details
Before executing an HTTP request to fetch external content, the AdminController::proxy controller validates the target URL using \Aimeos\Cms\Utils::isValidUrl($url). This function performs a DNS query to verify that the hostname does not resolve to private or reserved IP ranges (e.g., 127.0.0.1, 10.0.0.0/8, 169.254.169.254).
If the validation passes, the application proceeds to the "Use" phase, invoking Guzzle/cURL to send the request. However, Guzzle performs a second DNS lookup to establish the socket connection.
An attacker can exploit this by setting up a malicious DNS server for a domain they control and configuring it with a TTL of 0. 1. During the validation "Check", the DNS server returns a safe, public IP. 2. During the Guzzle "Use", the DNS server returns an internal/private IP.
### POC
1. Attacker registers rebound.test.com with a custom nameserver.
2. Attacker generates a valid proxy token (assuming basic authenticated access).
3. Attacker requests/cmsproxy?url=http://rebound.test.com.
4.isValidUrlchecksrebound.test.com. DNS returns8.8.8.8. Validation passes.
5. Guzzle requestshttp://rebound.test.com. DNS returns169.254.169.254`.
6. The CMS fetches AWS Instance Metadata and returns it to the attacker.

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
