How the Exploit Works
The vulnerability stems from a flaw in the password change mechanism of the Burk Technology ARC Solo. Specifically, the system fails to enforce proper authentication or session validation when receiving a password change request. This allows an attacker to send a password change request directly to the device’s HTTP endpoint without providing valid credentials, effectively bypassing the authentication process. Once the password has been changed, the attacker can gain full control over the device, leading to potential system compromise or data leakage.
Conceptual Example Code
Consider the following conceptual example of how this vulnerability might be exploited:
POST /password_change HTTP/1.1
Host: vulnerable_device.com
Content-Type: application/x-www-form-urlencoded
new_password=malicious_passwordIn the example above, an attacker sends a POST request to the `/password_change` endpoint of the device, supplying a new password (`malicious_password`). Because the device does not check for valid credentials or a valid session, it accepts the password change, allowing the attacker to take over the device.
Mitigation
The immediate recommended mitigation for this vulnerability is to apply the vendor-supplied patch. If a patch is not available or cannot be applied immediately, organizations should consider using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as temporary mitigation. These tools can help detect and block malicious requests to the `/password_change` endpoint, preventing attackers from exploiting this vulnerability.
