How the Exploit Works

The exploit targets the olws_handle_verify_phone() function in the Orion Login with SMS plugin. This function is vulnerable as it does not utilize a strong enough OTP value, exposes the hash needed to generate the OTP value, and does not impose restrictions on the number of attempts to submit the code. This allows attackers to bypass the authentication process. If an attacker has access to a user’s phone number, they can potentially log in as that user, including as an administrator. This vulnerability could lead to system compromise or data leakage.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited:

POST /olws_handle_verify_phone HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"phone_number": "target_phone_number",
"otp": "guess_otp"
}

The attacker would send a POST request to the olws_handle_verify_phone endpoint with the target’s phone number and a guessed OTP. As there are no restrictions on the number of attempts to submit the code, an attacker could potentially brute force the OTP.

Mitigation

To mitigate this vulnerability, it is recommended to apply the vendor-supplied patch. If the patch is not available, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. Regularly updating and patching your systems, as well as employing strong authentication methods, can also help prevent such vulnerabilities from being exploited.
