CWE-692 黑名单不完全导致跨站脚本

Incomplete Blacklist to Cross-Site Scripting

结构: Chain

Abstraction: Compound

状态: Draft

被利用可能性: unkown

基本描述

The product uses a blacklist-based protection mechanism to defend against XSS attacks, but the blacklist is incomplete, allowing XSS variants to succeed.

扩展描述

While XSS might seem simple to prevent, web browsers vary so widely in how they parse web pages, that a blacklist cannot keep track of all the variations. The "XSS Cheat Sheet" [REF-564] contains a large number of attacks that are intended to bypass incomplete blacklists.
