CWE-250 (带着不必要的权限执行) — Vulnerability Class 303

CWE-250 represents a critical architectural weakness where software executes operations using elevated privileges beyond what is strictly necessary for the task. This misconfiguration typically allows attackers to exploit other vulnerabilities, such as buffer overflows or injection flaws, by granting them higher-level access than intended. If an attacker compromises a low-privilege component, the excessive permissions amplify the impact, potentially leading to full system compromise or unauthorized data modification. To mitigate this risk, developers must adhere to the principle of least privilege, ensuring that each process or user account operates with only the minimum permissions required for its specific function. Implementing strict access controls, regularly auditing permission assignments, and isolating services further reduce the attack surface, thereby limiting the potential damage from any single security breach.
