CWE-286 (用户管理不正确) — Vulnerability Class 26

CWE-286 represents a critical user management weakness where software fails to correctly assign or maintain user roles and permissions within its operational environment. This flaw typically manifests when administrators or automated systems incorrectly map users to inappropriate permission groups, granting unintended access rights to sensitive data or system functions. Attackers exploit this vulnerability by manipulating user attributes or leveraging existing misconfigurations to escalate privileges, thereby gaining unauthorized access to resources they should not possess. To prevent such security breaches, developers must implement rigorous validation checks during user provisioning and role assignment processes. Employing the principle of least privilege ensures users receive only the minimum necessary access rights. Additionally, regular audits of user permissions and automated verification of role assignments help maintain integrity, ensuring that user management systems accurately reflect intended security policies and prevent unauthorized privilege escalation.
