CWE-353 (缺失完整性检查支持) — Vulnerability Class 30

CWE-353 represents a critical architectural weakness where software relies on transmission protocols lacking built-in integrity verification mechanisms, such as checksums or cryptographic hashes. This omission leaves data vulnerable to undetected corruption or malicious tampering during transit, as the application cannot distinguish between legitimate transmission errors and intentional alterations by an attacker. Exploitation typically involves intercepting and modifying data packets in transit, allowing adversaries to inject malicious payloads or alter critical information without triggering immediate detection by the receiving system. To mitigate this risk, developers must implement robust integrity checks at the application layer, utilizing algorithms like HMAC or SHA-256 to validate data authenticity. Additionally, employing secure transport protocols such as TLS ensures that data remains both encrypted and integrity-protected throughout the communication process, effectively closing this security gap.
