82 vulnerabilities classified as CWE-669 (在范围间的资源转移不正确). AI Chinese analysis included.
CWE-669 represents a critical architectural weakness where a system fails to properly manage the transfer of resources or behaviors between distinct security spheres, such as moving data from an untrusted network zone to a trusted internal environment. Attackers typically exploit this flaw by manipulating the context or metadata during the transition, thereby gaining unintended control over the resource or executing malicious code within a higher-privilege domain. This often occurs when boundary checks are insufficient or when trust assumptions are incorrectly applied across zones. To mitigate this risk, developers must implement rigorous validation and sanitization protocols at every sphere boundary. By strictly enforcing access controls and verifying the integrity of transferred data, engineers can prevent unauthorized privilege escalation and ensure that resources remain confined to their intended operational contexts, effectively neutralizing the potential for cross-sphere exploitation.
