CVE-2024-38468
📋 TL;DR
This vulnerability in Shenzhen Guoxin Synthesis image system allows attackers to reset passwords without authorization via the resetPassword API, potentially compromising user accounts. It affects systems running versions before 8.3.0, exposing them to unauthorized access and data breaches.
💻 Affected Systems
- Shenzhen Guoxin Synthesis image system
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full administrative control, leading to data theft, system manipulation, or deployment of ransomware across the network.
Likely Case
Unauthorized users reset passwords to access sensitive data or disrupt operations, resulting in data leaks or service interruptions.
If Mitigated
With strong network segmentation and monitoring, impact is limited to isolated systems, allowing quick detection and containment.
🎯 Exploit Status
Exploitation involves simple API calls; public proof-of-concept exists in GitHub references, making attacks easy to execute.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.3.0 or later
Vendor Advisory: Unknown, no vendor URL provided in references
Restart Required: Yes
Instructions:
1. Backup system data. 2. Download and install version 8.3.0 or later from the vendor. 3. Restart the system to apply changes. 4. Verify the fix by testing the resetPassword API.
🔧 Temporary Workarounds
Disable resetPassword API
linuxTemporarily disable or block access to the vulnerable resetPassword API endpoint to prevent exploitation.
Use firewall rules to block traffic to the API endpoint, e.g., iptables -A INPUT -p tcp --dport [API_PORT] -j DROP
Implement API authentication
allAdd authentication requirements to the resetPassword API to restrict unauthorized access.
Configure the system to require valid tokens or credentials for API calls; consult vendor documentation for specific steps.
🧯 If You Can't Patch
- Isolate the system on a segmented network to limit exposure and monitor for suspicious API activity.
- Implement strict access controls and multi-factor authentication to reduce the impact of compromised accounts.
🔍 How to Verify
Check if Vulnerable:
Test the resetPassword API without authentication; if it allows password reset, the system is vulnerable.Check Version:
Check the system version via vendor-specific command or interface; if below 8.3.0, it is vulnerable.Verify Fix Applied:
After patching, attempt the same unauthorized resetPassword API call; it should fail or require authentication.📡 Detection & Monitoring
Log Indicators:
- Unusual resetPassword API calls from unauthorized IPs or without authentication logs
Network Indicators:
- Spike in traffic to the resetPassword endpoint or unexpected password reset requests
SIEM Query:
Example: source_ip=* AND event_type='resetPassword' AND auth_status='failed'
