CVE-2024-0556
📋 TL;DR
A weak cryptography vulnerability in WIC200 version 1.1 allows remote attackers to intercept network traffic and decode base64-encoded credentials to plain text. This affects users of the vulnerable WIC200 device version, potentially exposing login credentials to unauthorized parties.
💻 Affected Systems
- Full Compass Systems WIC200
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative access to the device, pivot to internal networks, and compromise connected systems.
Likely Case
Attackers capture user credentials, gain unauthorized access to the device management interface, and potentially modify configurations.
If Mitigated
With network segmentation and monitoring, impact is limited to credential exposure without lateral movement.
🎯 Exploit Status
Exploitation requires network interception capabilities but uses simple base64 decoding of captured traffic.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in available references
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-full-compass-systems-wic1200
Restart Required: No
Instructions:
No official patch available. Contact vendor for updated firmware or mitigation guidance.
🔧 Temporary Workarounds
Network Segmentation
allIsolate WIC200 devices from untrusted networks and limit access to management interfaces.
Encrypted Communication Enforcement
allRequire HTTPS/TLS for all management traffic to prevent credential interception.
🧯 If You Can't Patch
- Replace vulnerable devices with updated hardware versions
- Implement network monitoring for credential capture attempts
🔍 How to Verify
Check if Vulnerable:
Check device firmware version via management interface; if version is 1.1, device is vulnerable.Check Version:
Check device web interface or console for firmware version informationVerify Fix Applied:
Verify firmware version has been updated beyond 1.1 through vendor-provided updates.📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts from new IP addresses
- Unusual administrative configuration changes
Network Indicators:
- Base64-encoded credentials in plaintext network traffic
- Unencrypted management protocol traffic
SIEM Query:
Search for base64 patterns in network traffic to/from WIC200 devices
