How the Exploit Works

The vulnerability stems from an issue within the send_email() function of the plugin. This function does not properly validate user input, permitting unauthenticated attackers to manipulate a request. This manipulation can result in the function revealing the contents of arbitrary files on the server.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. Note that this is a simplified example and may not reflect the exact process an attacker would use.

GET /wp-content/plugins/propovoice/send_email.php?file_path=/etc/passwd HTTP/1.1
Host: target.example.com

In this example, the attacker sends a GET request to the send_email.php file, including a ‘file_path’ parameter that points to “/etc/passwd”, a critical system file. If the server is vulnerable, its response would include the contents of the ‘/etc/passwd’ file.

Mitigation

Users of the Propovoice All-in-One Client Management System plugin for WordPress are advised to apply the vendor patch as soon as possible. If that is not immediately possible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy by blocking malicious requests.
