CVE-2022-50696
📋 TL;DR
SOUND4 IMPACT/FIRST/PULSE/Eco devices versions 2.x and below contain hardcoded credentials in server binaries that cannot be changed through normal operations. Attackers can use these static credentials to gain unauthorized access to affected devices without user interaction. This affects all deployments of these products across both Linux and Windows distributions.
💻 Affected Systems
- SOUND4 IMPACT
- SOUND4 FIRST
- SOUND4 PULSE
- SOUND4 Eco
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of affected devices allowing attackers to execute arbitrary code, steal sensitive data, pivot to internal networks, or disrupt critical audio/video operations.
Likely Case
Unauthorized access leading to configuration changes, data exfiltration, or device takeover for further attacks.
If Mitigated
Limited impact if devices are isolated in segmented networks with strict access controls and monitoring.
🎯 Exploit Status
Attack requires only knowledge of hardcoded credentials which are publicly documented. No user interaction needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://www.sound4.com/
Restart Required: No
Instructions:
No official patch available. Contact vendor for updated versions or replacement products.
🔧 Temporary Workarounds
Network Segmentation
allIsolate affected devices in separate network segments with strict firewall rules.
Access Control Lists
allImplement strict IP-based access controls to limit connections to trusted sources only.
🧯 If You Can't Patch
- Replace affected devices with newer versions or alternative products
- Implement network monitoring and intrusion detection specifically for authentication attempts using known hardcoded credentials
🔍 How to Verify
Check if Vulnerable:
Check device version against affected versions (2.x and below). Attempt authentication using publicly documented hardcoded credentials.Check Version:
Check device web interface or documentation for version information (vendor-specific).Verify Fix Applied:
Verify device is running version 3.0 or higher, or test that hardcoded credentials no longer work.📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts followed by successful login with same credentials
- Unusual login times or from unexpected IP addresses
Network Indicators:
- Authentication attempts using known hardcoded credential patterns
- Unexpected administrative access to device ports
