CVE-2024-9201: Seur Plugin SQL Injection Vulnerability

CVE-2024-9201 Overview

CVE-2024-9201 is a time-based SQL injection vulnerability affecting the SEUR plugin for PrestaShop in versions prior to 2.5.11. The vulnerability exists in the /modules/seur/ajax/saveCodFee.php endpoint, where the id_order parameter is not properly sanitized before being used in database queries. This allows remote attackers to inject malicious SQL statements that can extract sensitive data, modify database contents, or potentially gain complete control over the underlying database server.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability remotely to access, modify, or delete sensitive data from the PrestaShop database, including customer information, order details, and potentially administrator credentials.

Affected Products

• SEUR plugin for PrestaShop versions prior to 2.5.11
• PrestaShop installations using the vulnerable SEUR shipping module
• E-commerce platforms integrated with SEUR logistics services

Technical Details for CVE-2024-9201

Vulnerability Analysis

This SQL injection vulnerability allows attackers to manipulate database queries through the id_order parameter in the saveCodFee.php AJAX endpoint. The time-based nature of the injection means attackers can infer information from the database by measuring response delays caused by injected SQL statements containing time-delay functions like SLEEP() in MySQL.

The vulnerability requires no authentication, meaning any remote attacker with network access to the vulnerable endpoint can exploit it. The impact is severe as successful exploitation grants full read and write access to the database, potentially exposing sensitive customer data, payment information, and administrative credentials stored in the PrestaShop installation.

Root Cause

The root cause of CVE-2024-9201 is inadequate input validation and improper use of parameterized queries in the SEUR plugin. The id_order parameter passed to the /modules/seur/ajax/saveCodFee.php endpoint is directly incorporated into SQL queries without proper sanitization or the use of prepared statements. This classic SQL injection pattern (CWE-89) allows user-controlled input to alter the structure and logic of database queries.

Attack Vector

The attack vector is network-based, targeting the vulnerable AJAX endpoint accessible through HTTP requests. An attacker can craft malicious requests containing SQL injection payloads in the id_order parameter. Since this is a time-based blind SQL injection, the attacker uses conditional time delays to extract data character by character by observing response timing differences.

The vulnerability in the /modules/seur/ajax/saveCodFee.php endpoint allows attackers to inject SQL commands through the id_order parameter. Time-based SQL injection payloads using functions like SLEEP() or BENCHMARK() can be used to infer database contents by measuring response delays. For technical details and exploitation specifics, refer to the INCIBE Security Notice.

Detection Methods for CVE-2024-9201

Indicators of Compromise

• Unusual or repeated requests to /modules/seur/ajax/saveCodFee.php with abnormal id_order parameter values
• HTTP requests containing SQL syntax patterns such as SLEEP(), BENCHMARK(), WAITFOR, or comment sequences (--, /**/)
• Abnormally slow response times from the vulnerable endpoint indicating time-based injection attempts
• Database logs showing unexpected queries or syntax errors originating from the SEUR module

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the id_order parameter
• Monitor web server access logs for suspicious patterns targeting /modules/seur/ajax/saveCodFee.php
• Implement database query monitoring to identify anomalous queries with time-delay functions
• Configure alerting for requests with response times significantly exceeding normal thresholds

Monitoring Recommendations

• Enable detailed logging for all AJAX requests to PrestaShop modules
• Set up real-time alerting for SQL injection attack patterns in security monitoring tools
• Regularly review database audit logs for unauthorized data access or modifications
• Monitor for data exfiltration patterns that may indicate successful exploitation

How to Mitigate CVE-2024-9201

Immediate Actions Required

• Update the SEUR plugin to version 2.5.11 or later immediately
• If immediate patching is not possible, disable or restrict access to the /modules/seur/ajax/saveCodFee.php endpoint
• Review database logs for evidence of exploitation attempts
• Consider rotating database credentials and auditing for unauthorized data access

Patch Information

The vulnerability is addressed in SEUR plugin version 2.5.11. Administrators should update to this version or later through the PrestaShop module manager or by downloading the latest version from the official SEUR module repository. After updating, verify the installation and test that shipping functionality remains operational.

Workarounds

• Implement WAF rules to block requests containing SQL injection patterns to the vulnerable endpoint
• Restrict access to the /modules/seur/ajax/ directory using web server configuration rules
• Temporarily disable the SEUR module if shipping integration is not immediately critical
• Apply IP-based access controls to limit endpoint access to trusted networks only

# Apache .htaccess configuration to restrict access to vulnerable endpoint
<Files "saveCodFee.php">
    Order Deny,Allow
    Deny from all
    # Allow only from trusted IPs if needed
    # Allow from 192.168.1.0/24
</Files>
