How the Exploit Works
The Server-Side Request Forgery (SSRF) vulnerability in the Drupal AI SEO Link Advisor allows an attacker to make HTTP requests from the vulnerable server to another server, potentially within the same network. This gives them the ability to bypass network access controls and perform actions as if they were the server itself. This could lead to unauthorized actions such as data exfiltration, remote code execution, or even complete system compromise.
Conceptual Example Code
The following is a conceptual example of how this vulnerability might be exploited:
GET /?url=http://internal.victim.com HTTP/1.1
Host: vulnerable.example.comIn this example, the attacker sends a crafted GET request to the vulnerable server (`vulnerable.example.com`). The `url` parameter in the request specifies an internal resource (`internal.victim.com`) that the attacker wants the server to fetch. If the server is vulnerable to SSRF, it will fetch the resource and respond with its contents, potentially revealing sensitive internal information.
Mitigation Guidance
The most effective way to mitigate this vulnerability is to apply the vendor-supplied patch. For Drupal AI SEO Link Advisor, this means updating to version 1.0.6 or later. If a patch cannot be applied immediately, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to block or alert on potential SSRF attempts. However, these are temporary measures and should not replace patching the software as soon as possible.
