⚠️ Risk & Real-World Impact
Worst Case
Mass exposure of customer PII including addresses and billing information, deletion of all product reviews, and potential regulatory compliance violations.
Likely Case
Targeted exposure of specific customers' personal information and deletion of reviews, leading to privacy violations and loss of review content.
If Mitigated
Limited impact with proper access controls preventing unauthorized object reference.
🎯 Exploit Status
Exploitation requires creating a customer account first, then manipulating object IDs in URLs and parameters. Detailed exploitation methods are publicly documented.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
Check the Innoshop GitHub repository for updates. If a patch is released, update to the fixed version following standard software update procedures.
🔧 Temporary Workarounds
Implement Access Control Checks
allAdd server-side authorization checks to verify users can only access their own orders, addresses, and reviews.
Use Indirect Object References
allReplace direct object references with indirect references or tokens that cannot be easily enumerated.
🧯 If You Can't Patch
- Implement a web application firewall (WAF) with rules to detect and block IDOR patterns in URLs and parameters.
- Monitor application logs for suspicious access patterns to order, address, and review endpoints.
🔍 How to Verify
Check if Vulnerable:
Test if you can access /en/account/orders/[other_user_order_id] or manipulate shipping_address_id/billing_address_id parameters while logged in as a different user.Check Version:
Check the Innoshop version in your deployment configuration or admin panel.Verify Fix Applied:
Verify that access control checks prevent viewing other users' orders, addresses, and reviews after implementing fixes.📡 Detection & Monitoring
