⚠️ ADDITIONAL CONTEXT REQUIRED ⚠️

This vulnerability fix addresses CWE-326: 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

1. Review the fix to ensure it addresses all aspects of the vulnerability
2. Verify any required infrastructure or configuration changes
3. Check for data migration needs (existing encrypted/stored data, credentials, etc.)
4. Coordinate with relevant teams (frontend, infrastructure, security)
5. Consider impact on existing deployments

Vulnerability Information

• AppSecAI Vulnerability ID: 697d146670c412bec26d88be
• Vulnerability: CWE-326: Inadequate Encryption
• Severity: Medium
• File: src/main/java/org/owasp/benchmark/testcode/BenchmarkTest00684.java:66
• Detection Rule: Des Is Deprecated

Description: DES is considered deprecated. AES is the recommended cipher. Upgrade to use AES. See https://www.nist.gov/news-events/news/2005/06/nist-withdraws-outdated-data-encryption-standard for more information.

Security Impact

Risk if not fixed: This vulnerability could be exploited under certain conditions to compromise application security.

Risk level: Medium - Should be addressed in regular security maintenance

Triage Analysis

• Status: Confirmed vulnerability

• Severity: High

• Confidence: 100%

Analysis

Code explicitly uses DES encryption algorithm via Cipher.getInstance("DES/CBC/PKCS5PADDING") at line 66 and KeyGenerator.getInstance("DES") for key generation. DES is a deprecated 56-bit cipher officially withdrawn by NIST in 2005, matching the vulnerable pattern defined in security guidelines. While this is OWASP Benchmark test code designed to evaluate security scanners, the vulnerability pattern exists in the code.

Recommended Remediation

Replace DES with AES-256-GCM: Use Cipher.getInstance("AES/GCM/NoPadding"), generate 256-bit keys with KeyGenerator.getInstance("AES").init(256), and use 12-byte IVs. GCM mode provides authenticated encryption, protecting against both confidentiality and integrity attacks. Note: This is intentionally vulnerable test code from OWASP Benchmark Project v1.2 (BenchmarkTest00684.java), designed to verify security tool detection capabilities.
