How the Exploit Works

The vulnerability resides in the /_internal/redirect.php endpoint. This endpoint accepts a URL as an input, sends a request to this address, and then reflects the content in the response. Attackers can exploit this by providing a URL of a sensitive internal resource, which would normally be unreachable from the outside network, leading to SSRF. This allows the attacker to bypass firewalls and gain access to the internal network, potentially leading to system compromise or data leakage.

Conceptual Example Code

The following is a conceptual HTTP request that demonstrates how an attacker might exploit this vulnerability:

GET /_internal/redirect.php?url=http://internal-sensitive-resource HTTP/1.1
Host: vulnerable.example.com
Content-Type: application/json

The “url” parameter is manipulated to request a sensitive internal resource that should not be accessible from outside. The server then performs the request and returns the response, giving the attacker access to the sensitive data.

Mitigation and Prevention

Organizations are advised to apply the vendor-supplied patch immediately. If this is not possible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation against the exploit. Regularly updating and patching systems is critical for maintaining a strong security posture.
