How the Exploit Works
An attacker exploits this vulnerability by manipulating the controller’s webserver URL. Because the reference to the resource is externally controlled, the attacker could potentially gain access to sensitive resources. This unauthorized access could lead to a variety of negative outcomes, depending on the nature of the accessed resources.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. In this case, the attacker manipulates the URL to reference a resource that should not be accessible:
GET /controller/webserver/resource?ref=malicious_resource HTTP/1.1
Host: vulnerable.example.comThis request could potentially allow the attacker to access the ‘malicious_resource’, which may contain sensitive data or provide unauthorized control over the system.
Mitigation
The recommended mitigation for this vulnerability is to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. It is also advisable to regularly update and patch the system, and to follow best security practices for webserver configuration.
