CVE-2020-20128
📋 TL;DR
LaraCMS v1.0.1 transmits sensitive information in cleartext, allowing attackers to intercept credentials, session tokens, and other confidential data. This affects all deployments using the vulnerable version that handle authentication or sensitive data transmission.
💻 Affected Systems
- LaraCMS
📦 What is this software?
Laracms by Laracms Project
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise via credential theft leading to unauthorized administrative access, data exfiltration, and lateral movement within the network.
Likely Case
Session hijacking and credential theft enabling unauthorized access to user accounts and sensitive data.
If Mitigated
Limited impact if TLS/SSL is enforced at network boundaries, though internal traffic remains vulnerable.
🎯 Exploit Status
Exploitation requires network access to intercept traffic; no authentication needed. Public GitHub issues demonstrate the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.0.2 or later
Vendor Advisory: https://github.com/wanglelecc/laracms/issues/33
Restart Required: No
Instructions:
1. Update LaraCMS to version 1.0.2 or later. 2. Ensure all HTTP traffic is redirected to HTTPS. 3. Verify encryption is enforced for all sensitive transmissions.
🔧 Temporary Workarounds
Enforce HTTPS/TLS
allConfigure web server to force all HTTP traffic to HTTPS and use TLS encryption.
# For Apache: Redirect permanent / https://yourdomain.com/
# For Nginx: return 301 https://$server_name$request_uri;
Network Segmentation
allIsolate LaraCMS instance to a protected network segment with encrypted internal traffic.
🧯 If You Can't Patch
- Deploy a reverse proxy with TLS termination to encrypt all traffic to/from LaraCMS.
- Implement network-level encryption (IPsec/VPN) for all communications with the vulnerable system.
🔍 How to Verify
Check if Vulnerable:
Check if LaraCMS version is 1.0.1 and inspect network traffic for cleartext transmission of login credentials or session tokens.Check Version:
Check composer.json or application configuration for version; or inspect source code files for version markers.Verify Fix Applied:
Confirm version is 1.0.2+, test that all HTTP requests redirect to HTTPS, and verify no sensitive data is transmitted in cleartext.📡 Detection & Monitoring
Log Indicators:
- Failed login attempts from unexpected IPs
- Multiple session creations from single user
Network Indicators:
- Cleartext HTTP traffic containing 'password', 'token', or 'session' fields
- Unencrypted POST requests to login endpoints
SIEM Query:
