How the Exploit Works
The vulnerability arises from improper handling of HTTP POST requests by the fromRouteStatic function in the /goform/fromRouteStatic file. An attacker can exploit this flaw by sending a specially crafted HTTP POST request that contains an overly long ‘page’ argument. This could lead to a buffer overflow, potentially allowing the attacker to execute arbitrary code or cause a denial of service.
Conceptual Example Code
Here’s a hypothetical example of how an attacker might exploit the vulnerability:
POST /goform/fromRouteStatic HTTP/1.1
Host: vulnerable-device
Content-Type: application/x-www-form-urlencoded
page=A*50000In this example, the ‘page’ argument is filled with 50000 ‘A’ characters, which exceeds the buffer’s capacity and results in a buffer overflow.
Mitigation
The vendor has released a patch to address this vulnerability, and all affected users should apply this fix as soon as possible. Until the patch can be applied, users may also consider using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation measures. In all cases, it is crucial to monitor network traffic for any signs of exploitation of this vulnerability. It is also recommended to limit access to the affected devices to trusted networks and users, reducing the risk of potential attacks.
