CWE-450 UI输入的多重解释 类漏洞列表 2

CWE-450 UI输入的多重解释 类弱点 2 条 CVE 漏洞汇总,含 AI 中文分析。

CWE-450属于用户界面输入解释歧义漏洞。当系统对同一输入存在多种解析方式且未提示用户时,可能自动选择安全性较低的解释,导致意外行为。攻击者可构造特定输入,诱导系统执行非预期操作,如权限提升或数据篡改。开发者应明确定义输入解析规则,在存在歧义时强制要求用户确认,或采用单一、安全的默认解释策略,从而消除歧义风险。

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…
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.
