How the Exploit Works
The vulnerability is a stack overflow that is triggered via the radIpkey parameter in the web_radiusSrv_post function. An attacker can send a specially crafted request to the server containing an excessively long string in the radIpkey parameter. This causes an overflow in the stack, potentially leading to unexpected behavior such as crashing the system or even executing arbitrary code.
Conceptual Example Code
The following is a conceptual example of how an attack exploiting this vulnerability might look like. It represents a malicious HTTP POST request to the radius server with an excessively long radIpkey value:
POST /web_radiusSrv_post HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
radIpkey=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA... (continues)In this example, the string “A” is repeated to an excessive length, triggering the stack overflow. Please note that this is a simplistic conceptual representation and real-world attacks may be more complex and sophisticated.
Mitigation Guidance
Given the severity of this vulnerability, it is crucial to apply the vendor patch as soon as it becomes available to prevent potential exploitation. If the patch is not immediately available, users are advised to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. These tools can help detect and block attempts to exploit this vulnerability. Regular updates and patches coupled with robust security measures are the best defense against such threats.
