CWE-146 表达式/命令分隔符转义处理不恰当 类漏洞列表 9

CWE-146 表达式/命令分隔符转义处理不恰当 类弱点 9 条 CVE 漏洞汇总，含 AI 中文分析。

CWE-146 属于输入验证缺陷，指程序未正确过滤输入中的表达式或命令分隔符。攻击者通过注入特殊字符，误导下游组件解析逻辑，从而执行非预期操作或引发命令注入。开发者应严格实施输入验证，对敏感分隔符进行转义或白名单过滤，确保数据在传递至解析器前被安全中和，以阻断恶意指令的执行路径。

MITRE CWE 官方描述
CWE：CWE-146 表达式/命令分隔符的不当中和 英文：产品从上游组件接收输入，但未中和或不正确地中和了特殊元素，这些特殊元素在发送给下游组件时可能被解释为表达式或命令分隔符。 在解析数据时，注入的/缺失的/格式错误的分隔符可能导致进程采取意外操作。

Developers should anticipate that inter-expression and inter-command delimiters will be injected/removed/manipulated in the input vectors of their product. Use an appropriate combination of denylists and allowlists to ensure only valid, expected and appropriate input is processed by the system.
ImplementationAssume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does. When performing input validation, consider all potentially relevant properties, including length, type of input, the full range…
ImplementationWhile it is risky to use dynamically-generated query strings, code, or commands that mix control and data together, sometimes it may be unavoidable. Properly quote arguments and escape any special characters within those arguments. The most conservative approach is to escape or filter all characters that do not pass an extremely strict allowlist (such as everything that is not alphanumeric or whit…
ImplementationInputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
