| # Title : FoxCMS v1.0 php code innjection |
| # Author : indoushka |

POC :
[+] References : https://packetstorm.news/files/id/190551/ & CVE-2025-29306
[+] Summary
A critical remote code execution vulnerability exists in FoxCMS v1.0 that allows unauthenticated attackers to execute arbitrary operating system commands
via the 'id' parameter in the /images/index.html endpoint.
The vulnerability stems from improper input sanitization and direct code evaluation.
The vulnerability exists in the FoxCMS v1.0 /images/index.html endpoint where user-supplied input in the 'id' parameter is directly evaluated without proper sanitization.
The system fails to validate and sanitize user input, allowing attackers to inject and execute arbitrary PHP code.
[+] Vulnerable Code Pattern:
```php
// In /images/index.html or related component
<?php
// Vulnerable code structure (reconstructed)
$user_input = $_GET['id'];
// Input is directly evaluated without sanitization
eval("some_function($user_input);");
// Or similar dangerous construct
?>
[+] Usage:
Usage: php exploit.php https://victim.com "id"
