CVE-2024-38466
📋 TL;DR
Shenzhen Guoxin Synthesis image systems before version 8.3.0 have a hardcoded default password '123456Qw' that cannot be changed by users. This allows attackers to gain administrative access to the system. Any organization using affected versions of this image processing software is vulnerable.
💻 Affected Systems
- Shenzhen Guoxin Synthesis image system
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to access sensitive images, modify system configurations, install malware, or use the system as a foothold for lateral movement within the network.
Likely Case
Unauthorized access to sensitive image data, system configuration changes, and potential data exfiltration.
If Mitigated
No impact if password has been changed from default or if system is isolated from untrusted networks.
🎯 Exploit Status
Exploitation requires only knowledge of the default credentials and network access to the system. The GitHub references contain technical details about the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.3.0
Vendor Advisory: Unknown - no vendor advisory found in provided references
Restart Required: Yes
Instructions:
1. Upgrade to version 8.3.0 or later. 2. Verify the upgrade completed successfully. 3. Restart the system. 4. Change all passwords to strong, unique values.
🔧 Temporary Workarounds
Change Default Password
allManually change the default password to a strong, unique password if the system allows password changes in affected versions.
Specific commands unknown - use system administration interface
Network Isolation
linuxRestrict network access to the system using firewalls to only trusted IP addresses.
iptables -A INPUT -p tcp --dport [PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [PORT] -j DROP
🧯 If You Can't Patch
- Isolate the system on a segmented network with strict access controls
- Implement multi-factor authentication if supported, or place the system behind a VPN/proxy with additional authentication
🔍 How to Verify
Check if Vulnerable:
Attempt to authenticate to the system using username 'admin' and password '123456Qw'. If successful, the system is vulnerable.Check Version:
Check system administration interface or configuration files for version information (specific command unknown)Verify Fix Applied:
After upgrading to 8.3.0+, verify that the default password no longer works and that you can set a new strong password.📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts followed by successful login with default credentials
- Authentication logs showing login from unexpected IP addresses
Network Indicators:
- Unusual outbound connections from the image system
- Traffic patterns indicating data exfiltration
SIEM Query:
source="image_system_logs" (event_type="authentication_success" AND username="admin") OR (event_type="configuration_change" FROM unexpected_ip)
