CWE-312 (敏感数据的明文存储) — Vulnerability Class 243

CWE-312 represents a critical data protection weakness where sensitive information is stored in an unencrypted, readable format within a resource accessible to unauthorized entities. This flaw typically arises when developers fail to apply adequate cryptographic safeguards to data at rest, such as configuration files, logs, or local databases. Attackers exploit this vulnerability by gaining direct access to the storage medium, allowing them to easily extract credentials, personal identifiable information, or financial data without needing to bypass complex encryption algorithms. To mitigate this risk, developers must implement robust encryption standards, such as AES-256, for all sensitive data stored locally. Additionally, utilizing secure key management systems and ensuring that storage resources are strictly isolated from other control spheres helps prevent unauthorized access, thereby maintaining data confidentiality and integrity throughout its lifecycle.
