252 vulnerabilities classified as CWE-346 (源验证错误). AI Chinese analysis included.
CWE-346, Origin Validation Error, represents a critical weakness where software fails to adequately verify the authenticity or legitimacy of data sources and communication endpoints. Attackers typically exploit this vulnerability by spoofing trusted origins, such as forging HTTP headers or manipulating network packets to appear as if they originate from a legitimate internal system. This deception allows adversaries to bypass security controls, execute unauthorized actions, or inject malicious payloads that the application blindly trusts. To mitigate this risk, developers must implement robust validation mechanisms that strictly verify the source of incoming requests. This includes checking cryptographic signatures, validating domain names against a whitelist, and ensuring that sensitive operations are only performed when the origin is explicitly confirmed. By enforcing strict origin verification, organizations can prevent unauthorized access and maintain the integrity of their application logic against sophisticated spoofing attacks.
