CVE-2025-54981
📋 TL;DR
This vulnerability in Apache StreamPark uses weak encryption (AES-ECB mode) and a weak random number generator for encrypting sensitive data like JWT tokens. Attackers could potentially decrypt authentication data, compromising user sessions and sensitive information. It affects all StreamPark installations from version 2.0.0 up to (but not including) 2.1.7.
💻 Affected Systems
- Apache StreamPark
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of authentication system allowing attackers to forge valid JWT tokens, impersonate any user, access sensitive data, and potentially gain administrative privileges.
Likely Case
Attackers decrypt JWT tokens to hijack user sessions, access unauthorized data, and perform actions as authenticated users.
If Mitigated
Limited impact with proper network segmentation, monitoring, and quick detection of anomalous authentication patterns.
🎯 Exploit Status
Exploitation requires intercepting encrypted data and cryptographic analysis. No public exploit code has been released as of the advisory date.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.1.7
Vendor Advisory: https://lists.apache.org/thread/9rbvdvwg5fdhzjdgyrholgso53r26998
Restart Required: Yes
Instructions:
1. Download Apache StreamPark 2.1.7 from official sources. 2. Stop the StreamPark service. 3. Backup configuration and data. 4. Replace installation with version 2.1.7. 5. Restart the service. 6. Verify functionality.
🔧 Temporary Workarounds
Network Isolation
linuxRestrict network access to StreamPark instances to trusted networks only
iptables -A INPUT -p tcp --dport [streampark_port] -s [trusted_network] -j ACCEPT
iptables -A INPUT -p tcp --dport [streampark_port] -j DROP
JWT Token Monitoring
allImplement monitoring for JWT token usage patterns and revoke suspicious tokens
🧯 If You Can't Patch
- Implement strict network access controls to limit exposure to trusted sources only
- Deploy additional authentication layers and monitor for unusual authentication patterns
🔍 How to Verify
Check if Vulnerable:
Check StreamPark version via web interface or configuration files. If version is between 2.0.0 and 2.1.6 inclusive, system is vulnerable.Check Version:
Check application logs, configuration files, or use: grep -i version /path/to/streampark/config/*Verify Fix Applied:
After upgrade, confirm version is 2.1.7 or higher and verify encryption methods in configuration use secure algorithms (not AES-ECB).📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts followed by successful login
- Unusual JWT token generation patterns
- Authentication from unexpected IP addresses
Network Indicators:
- Unusual traffic patterns to authentication endpoints
- Multiple authentication requests from single source
