CWE-552 对外部实体的文件或目录可访问 类漏洞列表 213

CWE-552 对外部实体的文件或目录可访问 类弱点 213 条 CVE 漏洞汇总，含 AI 中文分析。

CWE-552属于权限配置不当类漏洞，指产品错误地将文件或目录暴露给未授权的外部实体。攻击者通常利用此缺陷，通过直接访问服务器根目录下的敏感文件，窃取机密数据或执行恶意操作。开发者应避免在Web或FTP服务器中存放敏感文件，并实施严格的访问控制机制，确保仅授权用户可访问特定资源，从而防止信息泄露。

MITRE CWE 官方描述
CWE：CWE-552 外部可访问的文件或目录 英文：The product makes files or directories accessible to unauthorized actors, even though they should not be. Web servers, FTP servers, and similar servers may store a set of files underneath a "root" directory that is accessible to the server's users. Applications may store sensitive files underneath this root without also using access control to limit which users may request those files, if any. Alternately, an application might package multiple files or directories into an archive file (e.g., ZIP or tar), but the application might not exclude sensitive files that are underneath those directories. In cloud technologies and containers, this weakness might present itself in the form of misconfigured storage accounts that can be read or written by a public or anonymous user.
