CVE-2024-23763

9.8 CRITICAL

📋 TL;DR

This SQL injection vulnerability in Gambio e-commerce software allows attackers to execute arbitrary SQL commands through crafted GET requests targeting the modifiers[attribute][] parameter. Attackers can potentially access, modify, or delete database content. All Gambio installations through version 4.9.2.0 are affected.

💻 Affected Systems

Products:
  • Gambio
Versions: through 4.9.2.0
Operating Systems: All platforms running Gambio
Default Config Vulnerable: ⚠️ Yes
Notes: All Gambio installations using the affected code path are vulnerable regardless of configuration.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise leading to data theft, data destruction, authentication bypass, and potential remote code execution via database functions.

🟠

Likely Case

Data exfiltration of customer information, order details, and administrative credentials stored in the database.

🟢

If Mitigated

Limited impact with proper input validation and database permissions, potentially only allowing data reading from specific tables.

🌐 Internet-Facing: HIGH - The vulnerability is exploitable via GET requests, making internet-facing installations immediately vulnerable to automated attacks.
🏢 Internal Only: MEDIUM - Internal systems are still vulnerable but require network access; risk depends on internal threat actors and lateral movement potential.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

The vulnerability requires only crafted HTTP GET requests, making it trivial to exploit with common SQL injection tools.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 4.9.2.1 or later

Vendor Advisory: https://herolab.usd.de/security-advisories/usd-2023-0047/

Restart Required: No

Instructions:

1. Backup your Gambio installation and database. 2. Download the latest Gambio version from official sources. 3. Replace affected files with patched versions. 4. Verify the installation works correctly.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement server-side input validation to sanitize the modifiers[attribute][] parameter

Implement parameter validation in your application code to reject suspicious input patterns

Web Application Firewall Rule

all

Block requests containing SQL injection patterns in the modifiers[attribute][] parameter

Configure WAF to block requests with SQL keywords in the modifiers[attribute][] parameter

🧯 If You Can't Patch

  • Implement strict input validation and parameterized queries for all user inputs
  • Restrict database user permissions to minimum required privileges

🔍 How to Verify

Check if Vulnerable:

Test by sending a crafted GET request with SQL injection payload in the modifiers[attribute][] parameter and observing database errors or unexpected behavior.

Check Version:

Check Gambio version in admin panel or via version files in installation directory

Verify Fix Applied:

After patching, attempt the same SQL injection test and verify it's blocked or sanitized properly.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL errors in application logs
  • Multiple failed login attempts following SQL error patterns
  • GET requests with unusual modifiers[attribute][] parameter values

Network Indicators:

  • HTTP GET requests containing SQL keywords (SELECT, UNION, INSERT, etc.) in URL parameters
  • Unusual database connection patterns from web server

SIEM Query:

source="web_logs" AND (url="*modifiers[attribute][]*" AND (url="*SELECT*" OR url="*UNION*" OR url="*INSERT*" OR url="*DELETE*"))
