CWE-75 (特殊命令到另一不同平面时的净化处理不恰当(特殊命令注入)) — Vulnerability Class 17

CWE-75 represents a critical input validation weakness where software fails to properly sanitize special elements that carry control implications, such as HTML tags, script blocks, or command-line arguments. This flaw typically allows attackers to inject malicious content into a different execution plane, enabling cross-site scripting, command injection, or code execution attacks. By bypassing expected input boundaries, adversaries can manipulate application behavior or steal sensitive user data. Developers mitigate this risk by implementing rigorous input validation and output encoding strategies. Specifically, they should strictly whitelist allowed characters, escape special symbols before rendering them in different contexts, and utilize parameterized queries for database interactions. Consistently applying these defensive coding practices ensures that user-controlled data remains inert, preventing unintended interpretation by the underlying system or client-side environment.
