CWE-326 (不充分的加密强度) — Vulnerability Class 115

CWE-326 represents a critical cryptographic weakness where sensitive data is protected by encryption algorithms that, while theoretically valid, lack the necessary strength to withstand modern computational attacks. This vulnerability typically manifests when developers employ outdated ciphers, insufficient key lengths, or deprecated protocols, leaving data vulnerable to brute-force attacks that can successfully decrypt information using readily available resources. Attackers exploit this by intercepting transmitted data or accessing stored files, bypassing security controls through sheer computational power rather than complex mathematical breakthroughs. To mitigate this risk, developers must adhere to current cryptographic standards, utilizing robust algorithms like AES with adequate key sizes, and regularly updating libraries to ensure encryption strength aligns with contemporary threat landscapes and regulatory compliance requirements.
