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: 69654fbffc355c4beda09b76 Vulnerability: Weak Encryption Algorithm CWE Classification: CWE-326 Severity: Medium File: src/main/java/org/owasp/benchmark/testcode/BenchmarkTest02658.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 at line 65 with Cipher.getInstance('DES/CBC/PKCS5PADDING'). DES is cryptographically broken, uses only 56-bit keys (far below the 256-bit minimum), and is explicitly listed as vulnerable in security guidelines. While this is OWASP Benchmark test code designed to demonstrate vulnerabilities, the vulnerable pattern exists and should be classified as such - test code often becomes production code. Recommended Remediation Replace DES with AES-256-GCM. Change Cipher.getInstance('DES/CBC/PKCS5PADDING') to Cipher.getInstance('AES/GCM/NoPadding'), update KeyGenerator.getInstance('DES') to KeyGenerator.getInstance('AES') with keyGen.init(256), and use 12-byte IV for GCM mode. Implement authenticated encryption for integrity protection. Remediation Details Fix Description: The weak encryption vulnerability has been fixed by upgrading from DES to AES. The three critical changes made were: IV size: Updated from 8 bytes to 16 bytes (line 57) - AES requires a 16-byte initialization vector for CBC mode Cipher algorithm: Changed from "DES/CBC/PKCS5PADDING" to "AES/CBC/PKCS5PADDING" (line 62) Key generator: Changed from "DES" to "AES" (line 65) Summary Vulnerability: The code used DES (Data Encryption Standard), a deprecated encryption algorithm vulnerable to brute-force attacks due to its small 56-bit key size. DES is considered cryptographically broken and unsuitable for protecting sensitive data. Fix: Upgraded to AES (Advanced Encryption Standard), the current industry-standard encryption algorithm. AES provides strong encryption with larger key sizes (128, 192, or 256 bits) and is resistant to known cryptographic attacks. The fix maintains the CBC mode and PKCS5 padding for compatibility while strengthening the underlying cipher. Migration Guidance: This fix is backward incompatible with data previously encrypted using DES. Any existing encrypted data will need to be decrypted with the old DES key and re-encrypted with the new AES implementation. Since this appears to be test code (OWASP Benchmark), existing encrypted files can be safely discarded and regenerated. 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.
