How the Exploit Works
The vulnerability stems from a missing authorization flaw in the affected Ivanti products. An attacker with read-only admin privileges can exploit this flaw to manipulate authentication-related settings. This can allow them to escalate their privileges, gain unauthorized access, or alter system configurations, potentially leading to system compromise or data leakage. The attack can be carried out remotely over a network without any user interaction, making it a particularly dangerous vulnerability.
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited. In this scenario, an HTTP request is used to manipulate authentication settings on a vulnerable endpoint:
POST /api/v1/auth-config HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer READ-ONLY-ADMIN-TOKEN
{
"auth_method": "None",
"allow_unauthenticated": true
}In this example, the attacker is using their read-only admin privileges to change the authentication method to ‘None’ and allow unauthenticated access, potentially granting them unrestricted access to sensitive system resources.
Mitigation Guidance
To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as possible. Ivanti has released fixes for all affected products. If immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation, helping to detect and block exploit attempts.
