This vulnerability in Apache StreamPark stems from the use of a static, hard-coded encryption key within the application’s codebase for cryptographic operations. Instead of utilizing a securely managed, dynamically generated, or configurable key, the system relies on a fixed string embedded in the source. This key is used to encrypt and decrypt sensitive data such as configuration details or connection credentials. An attacker can easily extract this immutable key by decompiling the application JAR files or directly examining the source code if available. Once obtained, the attacker can decrypt any sensitive information previously encrypted by the system, leading to full information disclosure. Furthermore, possessing the key allows the malicious actor to forge valid encrypted payloads, potentially enabling unauthorized access to the system by impersonating legitimate components or users, as the system will trust any data encrypted with the known key.
Platform: Apache StreamPark
Version: 2.0.0 – 2.1.6
Vulnerability: Hard-coded Key
Severity: High
date: 2024-12-12
Prediction: 2024-12-12 Patched
What Undercode Say:
grep -r "encrypt.key" --include=".java" --include=".properties" .
strings target/streampark-.jar | grep -i "key"
find . -name ".jar" -exec jar tf {} \; | grep -i properties
// Example pattern to find in code public static final String SECRET_KEY = "STREAMPARK_FIXED_KEY";
How Exploit:
1. Obtain application JAR.
2. Decompile/analyze code.
3. Extract hard-coded key.
4. Decrypt stored sensitive data.
5. Forge malicious encrypted payloads.
Protection from this CVE
Upgrade to version 2.1.7 immediately. Implement external, secure key management (e.g., HSM, vault). Rotate all previously encrypted data. Audit code for other static secrets.
Impact:
Data confidentiality breach. Unauthorized system access. Potential authentication bypass.
