CWE-708 (不正确的属主授予) — Vulnerability Class 20

CWE-708, Incorrect Ownership Assignment, is a critical vulnerability where a software system improperly designates a resource owner, granting control to an entity outside the intended security boundary. This flaw typically arises when applications fail to validate or enforce ownership constraints during resource creation or modification, allowing attackers to manipulate files, database records, or configuration settings. Exploitation often involves privilege escalation or unauthorized data alteration, as malicious actors leverage the misassigned ownership to bypass access controls and execute actions reserved for legitimate administrators. To mitigate this risk, developers must implement strict validation checks that verify the current user’s authority before assigning ownership. Utilizing principle of least privilege, enforcing immutable ownership policies, and conducting regular code reviews to identify trust boundary violations are essential strategies. By ensuring that only authorized entities can assume control over sensitive resources, organizations can effectively prevent unauthorized manipulation and maintain system integrity against internal and external threats.
