CWE-158 空字节或NULL字符转义处理不恰当 类漏洞列表 21

CWE-158 空字节或NULL字符转义处理不恰当 类弱点 21 条 CVE 漏洞汇总,含 AI 中文分析。

CWE-158 属于输入验证缺陷,指程序未正确处理或过滤输入中的空字节(NUL)。攻击者通过注入空字节,利用底层语言(如 C/C++)以空字符作为字符串终止符的特性,截断预期输入或改变数据解析逻辑,从而绕过安全限制或引发缓冲区溢出。开发者应严格实施输入验证,拒绝包含空字节的非法输入,或在处理前显式移除、转义空字符,确保数据在组件间传递时的完整性与正确解析。

MITRE CWE 官方描述
CWE:CWE-158 未正确处理空字节或NUL字符 英文:产品从上游组件接收输入,但在将NUL字符或空字节发送给下游组件时,未对其进行中和或中和不正确。 在解析数据时,注入的NUL字符或空字节可能导致产品认为输入在其实际结束位置之前就已终止,或以其他方式导致输入被错误解释。这可用于注入潜在的危险输入(该输入位于空字节之后),或绕过验证例程及其他保护机制。

Developers should anticipate that null characters or null bytes 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…
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.
