Description: ⚠️ ADDITIONAL CONTEXT REQUIRED ⚠️ This vulnerability fix addresses Inadequate Encryption Strength, which typically requires coordination beyond a single code change. Why Additional Context May Be Needed: Requires updating cryptographic algorithms/methods and handling data already encrypted or hashed with the weak algorithm Technical Considerations: Existing encrypted/hashed data cannot be automatically converted without the original plaintext Recommended Actions: Review the fix to ensure it addresses all aspects of the vulnerability Verify any required infrastructure or configuration changes Check for data migration needs (existing encrypted/stored data, credentials, etc.) Coordinate with relevant teams (frontend, infrastructure, security) Consider impact on existing deployments Vulnerability Information AppSecAI Vulnerability ID: 6914fa3a28b9e848644fceb2 Vulnerability: Weak Encryption Algorithm CWE Classification: CWE-326 Severity: Medium File: src/main/java/org/owasp/benchmark/testcode/BenchmarkTest01320.java Detection Rule: java.lang.security.audit.crypto.desede-is-deprecated.desede-is-deprecated Description: Triple DES (3DES or DESede) is considered deprecated. AES is the recommended cipher. Upgrade to use AES. Triage Analysis Status: Confirmed vulnerability Security Assessment: Severity: High Confidence: 100% Analysis The code uses DES encryption algorithm (Cipher.getInstance('DES/CBC/PKCS5Padding')) which is cryptographically broken and deprecated. DES has a 56-bit effective key length, making it vulnerable to brute-force attacks with modern hardware. The code explicitly instantiates DES cipher and key generation. While this is OWASP Benchmark test code intentionally containing vulnerabilities, the vulnerability pattern is real and correctly identified. Recommended Remediation Replace DES with AES-256-GCM: Use Cipher.getInstance('AES/GCM/NoPadding') with 256-bit keys generated via KeyGenerator.getInstance('AES').init(256). GCM mode provides authenticated encryption with integrity protection. Generate 12-byte IVs using SecureRandom for each encryption operation. Remediation Details Fix Description: Security Fix Complete The weak encryption vulnerability has been remediated by upgrading from DES to AES-128. The changes made were: Modified Lines: Line 60: Updated IV generation from 8 bytes to 16 bytes (AES requirement) Line 64: Changed cipher algorithm from DES/CBC/PKCS5Padding to AES/CBC/PKCS5Padding Line 66: Updated key generator from DES to AES Summary: DES (Data Encryption Standard) is cryptographically broken and vulnerable to brute force attacks. It uses a 56-bit effective key length, which can be cracked in hours using modern hardware. The fix upgrades to AES (Advanced Encryption Standard), which is the current industry-standard symmetric encryption algorithm recommended by NIST. AES provides significantly stronger security with a default 128-bit key length (expandable to 192 or 256 bits). The fix maintains complete API compatibility - all method signatures, return types, exception handling, and functional behavior remain unchanged. The encryption operation continues to work identically from the caller's perspective, but now uses a secure algorithm. No new dependencies are required as both DES and AES are part of Java's standard Cryptography Extension (JCE). Changes Made: Updated source code with secure implementation This PR was generated automatically to address a security vulnerability. Please review the changes carefully before merging.
