How the Exploit Works
This vulnerability stems from an insufficient control mechanism in HikCentral Professional’s authentication process. An unauthenticated attacker can craft a network request that bypasses the standard authentication process, granting them admin permissions. This elevated access allows them to change system configurations, access sensitive data, or even take control of the system.
Conceptual Example Code
Conceptualizing this vulnerability, an attacker could craft a HTTP request to a vulnerable endpoint like below:
POST /admin/access HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "user_role": "admin" }In this example, the attacker sends a POST request to the `/admin/access` endpoint, pretending to be an administrator. The server, due to the vulnerability, fails to validate the user’s authenticity and grants admin privileges.
Mitigation Guidance
The immediate mitigation for this vulnerability involves applying the vendor patch as soon as it becomes available. If the vendor patch isn’t immediately available, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. These systems can be configured to block or alert on the network requests indicative of this exploit.
However, the ultimate solution is patching the software to a version where the vulnerability is fixed. Always stay updated with the latest security patches and follow best practices for secure software usage.
