How the Exploit Works
The exploitation of this vulnerability stems from insufficient file path validation in the qcld_openai_delete_training_file() function in the WPBot Pro WordPress Chatbot plugin. This flaw allows an authenticated attacker, with at least Subscriber-level access, to delete arbitrary files on the server. When a critical file such as wp-config.php is deleted, it can pave the way for remote code execution. This potential exploit can lead to system compromise or data leakage, causing significant damage to the affected party.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited using a HTTP request:
POST /wpbotpro/qcld_openai_delete_training_file HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer [AUTH_TOKEN]
{ "file_path": "../../wp-config.php" }In the example above, the malicious request targets the qcld_openai_delete_training_file function with a file_path parameter pointing to the wp-config.php file. This file is critical to the operation of the WordPress site, and its deletion could easily lead to remote code execution.
Mitigation
To mitigate this vulnerability, users of the affected plugin are advised to apply the vendor patch as soon as it is available. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. Regularly updating software and maintaining good cybersecurity hygiene can also help to minimize the risk of exposure to such vulnerabilities.
