Craft Commerce is vulnerable to SQL Injection in Commerce Inventory Table Sorting

Summary

Craft Commerce is vulnerable to SQL Injection in the inventory levels table data endpoint. The sort[0][direction] and sort[0][sortField] parameters are concatenated directly into an addOrderBy() clause without any validation or sanitization. An authenticated attacker with access to the Commerce Inventory section can inject arbitrary SQL queries, potentially leading to a full database compromise.

Required Permissions

• General
  • Access the control panel
  • Access Craft Commerce
• Craft Commerce
  • Manage inventory stock levels

Steps to reproduce

1. Log in to the control panel
2. Navigate to Commerce > Inventory
3. Click on any sortable column header (e.g., "SKU") to trigger a sort request
4. Intercept the request and modify sort[0][direction] or sort[0][sortField] parameters and append ,sleep(2) payload to it's current value as follows:

# sort[0][sortField]=sku,sleep(2)
GET /index.php?p=admin/actions/commerce/inventory/inventory-levels-table-data&sort[0][sortField]=sku,sleep(2)&sort[0][direction]=asc&inventoryLocationId=1&containerId=%23inventory-levels
# sort[0][direction]=asc,sleep(2)
GET /index.php?p=admin/actions/commerce/inventory/inventory-levels-table-data&sort[0][sortField]=sku&sort[0][direction]=asc,sleep(2)&inventoryLocationId=1&containerId=%23inventory-levels

6. Observe the delay in the response, confirming the injection

Alternatively, you can use the following curl (bash syntax) command (replace cookie and target domain as needed):

# sort[0][sortField]=sku,sleep(2)
