CVE-2024-1530

Executive Summary

CVE-2024-1530 is a critical SQL injection vulnerability discovered in ECshop version 4.1.8, specifically within the /admin/view_sendlist.php file. The vulnerability allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion. The exploit has been publicly disclosed, increasing the risk of active exploitation. The vendor has not released a patch, leaving all instances of ECshop 4.1.8 vulnerable. This report provides a comprehensive technical analysis, detection methods, and mitigation strategies.

Supply Chain & Package Security

ECshop is a widely used open-source e-commerce platform, particularly in Chinese-speaking markets. The vulnerability in the admin panel poses a significant supply chain risk, as compromised ECshop instances can lead to data breaches affecting customers, order information, and payment details. Organizations using ECshop should treat this as a high-priority security incident and immediately isolate affected systems.

CVSS Breakdown & Threat Level

• CVSS Score: 6.3 (Medium)
• Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
• Attack Vector: Network
• Attack Complexity: Low
• Privileges Required: None
• User Interaction: None
• Scope: Unchanged
• Confidentiality Impact: Low
• Integrity Impact: Low
• Availability Impact: Low

Threat Level: High (due to public exploit availability and lack of patch)

Deep Dive & Mechanics

The vulnerability resides in the /admin/view_sendlist.php file of ECshop 4.1.8. The file likely processes user-supplied input (e.g., via GET or POST parameters) without proper sanitization or parameterized queries. An attacker can manipulate SQL queries by injecting malicious SQL code through the vulnerable parameter.

Root Cause: The application directly concatenates user input into SQL queries without using prepared statements or input validation.

Attack Vector: Remote, unauthenticated HTTP requests to the vulnerable endpoint.

Impact: Successful exploitation can allow an attacker to:

• Extract sensitive data (user credentials, order details, payment information).
• Modify or delete database records.
• Potentially escalate privileges or execute administrative actions.

Vulnerable vs. Patched Code

Vulnerable Code (Conceptual):

// /admin/view_sendlist.php
$id = $_GET['id'];
$sql = "SELECT * FROM ecs_sendlist WHERE id = '$id'";
$result = $db->query($sql);

Patched Code (Conceptual):

// /admin/view_sendlist.php
$id = intval($_GET['id']);
$sql = "SELECT * FROM ecs_sendlist WHERE id = ?";
$stmt = $db->prepare($sql);
$stmt->bind_param("i", $id);
$stmt->execute();
$result = $stmt->get_result();

Note: Since no official patch exists, the above is a recommended fix. The vendor must implement parameterized queries or input validation.

Exploitation & Lab Setup

Red Team (Exploitation)

Prerequisites:

• Target running ECshop 4.1.8.
• Network access to the /admin/view_sendlist.php endpoint.

Exploit Payload:

GET /admin/view_sendlist.php?id=1' UNION SELECT 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100-- -

Manual Exploitation Steps:

1. Identify the vulnerable parameter (likely id).
2. Inject a single quote (') to break the SQL query.
3. Use UNION SELECT to extract data from other tables.
4. Enumerate database structure using information_schema.

Automated Exploitation (sqlmap):

sqlmap -u "http://target.com/admin/view_sendlist.php?id=1" --batch --dbs

Blue Team (Detection & Response)

Detection Steps:

1. Monitor web server logs for suspicious requests to /admin/view_sendlist.php containing SQL keywords (UNION, SELECT, ', --).
2. Enable WAF rules to block SQL injection patterns.
3. Review database logs for anomalous queries.

Response:

1. Immediately isolate the affected server.
2. Take a forensic image of the system.
3. Rotate all credentials stored in the database.
4. Apply virtual patching via WAF until an official patch is available.

Indicators of Compromise (IOCs)

Network IOCs:

• HTTP requests to /admin/view_sendlist.php with parameters containing SQL injection patterns.
• Outbound database connections from the web server to unknown IPs.

File IOCs:

• Modified /admin/view_sendlist.php file (check for backdoors).
• Suspicious files in the admin/ directory.

Log IOCs:

• Web server logs showing 400 or 500 errors from /admin/view_sendlist.php.
• Database logs showing UNION, SELECT, or INFORMATION_SCHEMA queries.

Remediation & Mitigation

Immediate Actions:

1. Isolate the affected ECshop instance from the network.
2. Apply virtual patching using a WAF to block SQL injection patterns.
3. Review and rotate all database credentials and API keys.

Long-term Fix:

• Upgrade to a patched version of ECshop (if available).
• Implement input validation and parameterized queries in all database interactions.
• Conduct a security audit of the entire application.

Workaround:

• Disable the /admin/view_sendlist.php endpoint if not required.
• Restrict access to the admin panel via IP whitelisting or VPN.
