How the Exploit Works
The vulnerability exists because the Service Finder SMS System plugin does not properly verify a user’s phone number before allowing them to log in. An attacker can exploit this by sending a specially crafted request to the login endpoint with an arbitrary phone number. If the phone number is associated with a user account, the attacker is logged in as that user without needing to provide a password.
Conceptual Example Code
To illustrate the vulnerability, consider the following conceptual example. An attacker could send an HTTP POST request to the login endpoint with an arbitrary phone number in the body of the request:
POST /wp-login.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
phone_number=1234567890In this example, if there is a user associated with the phone number `1234567890`, the attacker would be logged in as that user.
Mitigation
Until a patch is released by the vendor, users of the Service Finder SMS System plugin can mitigate the risk of this vulnerability by implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS). These systems can analyze incoming traffic and block suspicious requests that aim to exploit this vulnerability. Once the patch is available, it should be applied immediately to prevent further potential exploits.
Remember, cybersecurity is an ongoing effort. Stay informed about the latest vulnerabilities and ensure you apply patches and updates as soon as they are available.
