KB Support – Customer Support Ticket & Helpdesk Plugin | <= 1.7.4 How the Exploit Works

The vulnerability exists in KB Support – Customer Support Ticket & Helpdesk Plugin for WordPress due to insecure storage of data in the ‘kbs’ directory. Unauthenticated attackers can exploit this by accessing the ‘/wp-content/uploads/kbs’ directory, which may contain sensitive file attachments included in support tickets.

Conceptual Example Code

Below is a conceptual example of how an HTTP request to the vulnerable endpoint might look:

GET /wp-content/uploads/kbs/sensitive_file.txt HTTP/1.1
Host: vulnerablewebsite.com

In this example, the attacker sends an HTTP GET request to retrieve a sensitive file (sensitive_file.txt) from the insecurely stored directory.

Mitigation Guidance

The best way to mitigate this vulnerability is by applying the vendor’s patch. If the patch cannot be applied immediately, a temporary solution would be to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability.
