CWE-913 (动态管理代码资源的控制不恰当) — Vulnerability Class 47

CWE-913 represents a critical weakness where software fails to properly restrict access to dynamically-managed code resources, including variables, objects, classes, and executable instructions. This vulnerability typically arises in languages supporting dynamic code generation or modification, such as JavaScript or Python, where attackers exploit insufficient validation to inject malicious scripts or alter runtime behavior. By manipulating these dynamic elements, adversaries can achieve remote code execution, data injection, or privilege escalation, bypassing standard security controls. To mitigate this risk, developers must enforce strict input validation and sanitization on all dynamic inputs. Implementing robust access controls, utilizing secure coding frameworks that limit dynamic execution capabilities, and adopting a principle of least privilege for runtime environments are essential strategies. Regular security audits and static analysis tools further help identify and remediate these dangerous dynamic resource interactions before deployment.
