CVE-2021-47763
📋 TL;DR
Aimeos 2021.10 LTS contains a SQL injection vulnerability in the JSON API's 'sort' parameter that allows attackers to execute arbitrary SQL queries. Attackers can exploit this by sending crafted GET requests to the jsonapi/review endpoint to extract database information. This affects all systems running the vulnerable Aimeos version with the JSON API accessible.

⚠️ Risk & Real-World Impact
Worst Case
Full database compromise including data exfiltration, modification, or deletion; potential privilege escalation to execute arbitrary commands on the database server.
Likely Case
Extraction of sensitive data from the database such as user credentials, personal information, or business data.
If Mitigated
Limited information disclosure about database structure if input validation blocks malicious payloads.
🎯 Exploit Status
Exploit code is publicly available on Exploit-DB. The vulnerability requires minimal technical skill to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2021.10.1 or later
Vendor Advisory: https://aimeos.org
Restart Required: No
Instructions:
1. Update Aimeos to version 2021.10.1 or later via composer. 2. Run 'composer update aimeos/aimeos-laravel'. 3. Clear any application caches if applicable.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation on the 'sort' parameter to only allow alphanumeric characters and underscores.
Modify the JSON API controller to sanitize the sort parameter before processing
Endpoint Restriction
allRestrict access to the jsonapi/review endpoint using web server rules or application firewalls.
Add IP-based restrictions or authentication requirements to the endpoint
🧯 If You Can't Patch
- Implement a Web Application Firewall (WAF) with SQL injection detection rules
- Disable or restrict access to the JSON API endpoints entirely
🔍 How to Verify
Check if Vulnerable:
Test by sending a GET request to /jsonapi/review with a malicious sort parameter like 'sort=1 AND (SELECT * FROM information_schema.tables)' and checking for database errors or unexpected responses.Check Version:
composer show aimeos/aimeos-laravel | grep versionVerify Fix Applied:
After patching, repeat the same test and verify that malicious sort parameters are rejected or sanitized without executing SQL.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests to jsonapi/review with complex sort parameters
- Database query logs showing unexpected UNION or SELECT statements
Network Indicators:
- HTTP GET requests to /jsonapi/review with SQL keywords in parameters
- Unusual traffic patterns to the JSON API endpoint
SIEM Query:
source="web_logs" AND uri="/jsonapi/review" AND (param="*sort*" AND (param="*SELECT*" OR param="*UNION*" OR param="*FROM*"))
