Version 1.0 of the WordPress plugin, google-maps-by-daniel-martyn, is vulnerable to remote code execution (RCE). The plugin writes user data to the file version.php, which can be accessed by malicious users.
- The attacker sends an HTTP POST request to the vulnerable WordPress plugin with PHP code in the body. The server writes the attacker’s PHP code to the file version.php.
- The server replies with an HTTP 200 OK and the HTML character encoded PHP payload in the response body.
- The attacker sends an HTTP GET request to access and execute version.php, achieving RCE.
The vulnerable file can be accessed directly by unauthenticated attackers.
