How the Exploit Works

The exploit takes advantage of publicly accessible log files that are automatically created by the PayHere Payment Gateway WordPress plugin. These logs contain sensitive information about transactions. An attacker can remotely access these logs without requiring any special privileges or user interaction. By utilizing this loophole, an attacker can collect sensitive data, which could potentially be used for malicious activities such as identity theft, fraud, or unauthorized system access.

Conceptual Example Code

This is a conceptual example of how an attacker might exploit this vulnerability. The attacker makes a GET request to the file hosting the logs:

GET /wp-content/plugins/payhere-gateway/logs/transaction.log HTTP/1.1
Host: target.example.com

The server would then respond with the log file containing sensitive transaction information.

Mitigation

Users of the PayHere Payment Gateway WordPress Plugin are recommended to update the plugin to version 2.2.12 or later, which contains a patch for this vulnerability. Temporary mitigation can also be achieved by utilizing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to monitor and block suspicious network traffic.
