This vulnerability occurs when an application fails to properly validate integrity check values such as checksums, hashes, or message authentication values before processing data. As a result, modified, corrupted, or maliciously tampered data may be accepted as legitimate. Attackers may exploit this weakness to inject unauthorized content, bypass integrity protections, or manipulate communications between systems.

Remediation Recommendation

Ensure all integrity check values are validated against independently calculated values before processing or trusting incoming data. Implement checksum or cryptographic integrity verification according to the relevant protocol or specification, and reject any data that fails validation checks.
