CVE-2024-11619
📋 TL;DR
This vulnerability in macrozheng mall's JWT Token Handler allows attackers to forge authentication tokens by exploiting the use of a default cryptographic key. Systems running affected versions could have their authentication bypassed. The vulnerability affects all deployments using the default configuration.

⚠️ Risk & Real-World Impact
Worst Case
Complete authentication bypass allowing unauthorized access to user accounts, administrative functions, and sensitive data.
Likely Case
Authentication bypass for some users or functions, potentially leading to unauthorized data access or privilege escalation.
If Mitigated
Minimal impact if custom cryptographic keys are properly configured and strong authentication controls are in place.
🎯 Exploit Status
Exploitation requires understanding of JWT token structure and cryptographic weaknesses, but no public exploit code is available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
No official patch available. Vendor did not respond to disclosure and deleted GitHub issue. Consider upgrading to any newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Configure Custom JWT Secret Key
allReplace the default cryptographic key with a strong, unique secret key for JWT token signing and verification.
Edit application configuration to set jwt.secret property to a strong random value (minimum 256 bits)
Implement JWT Key Rotation
allRegularly rotate JWT signing keys and implement proper key management.
Implement key rotation schedule and update jwt.secret property periodically
🧯 If You Can't Patch
- Implement network segmentation to isolate vulnerable systems from critical assets
- Deploy Web Application Firewall (WAF) with JWT validation rules
🔍 How to Verify
Check if Vulnerable:
Check if application uses default JWT configuration by examining configuration files for jwt.secret property or checking if tokens can be decoded with common default keys.Check Version:
Check application version in pom.xml or application.properties for version <= 1.0.3Verify Fix Applied:
Verify that JWT tokens cannot be forged using default keys and that custom secret key is properly configured.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts followed by successful login with unusual patterns
- JWT token validation errors or warnings
Network Indicators:
- Unusual authentication traffic patterns
- Requests with manipulated JWT tokens
SIEM Query:
Authentication logs where JWT tokens show signs of tampering or use of default key signatures
