CWE-426 不可信的搜索路径 类弱点 208 条 CVE 漏洞汇总，含 AI 中文分析。
CWE-426 属于不信任搜索路径漏洞，指程序使用外部提供的路径查找关键资源，导致可能访问不受控的文件。攻击者常通过操纵环境变量或配置，将恶意程序或数据注入搜索路径，从而执行任意代码或窃取敏感信息。开发者应避免使用动态搜索路径，改用硬编码的绝对路径，或严格验证路径来源及权限，确保仅加载受信任目录下的资源，以阻断攻击链。
#define DIR "/restricted/directory" char cmd[500]; sprintf(cmd, "ls -l %480s", DIR); /* Raise privileges to those needed for accessing DIR. */ RaisePrivileges(...); system(cmd); DropPrivileges(...); ...The user sets the PATH to reference a directory under the attacker's control, such as "/my/dir/". The attacker creates a malicious program called "ls", and puts that program in /my/dir The user executes the program. When system() is executed, the shell consults the PATH to find the ls program The program finds the attacker's malicious program, "/my/dir/ls". It doesn't find "/bin/ls" because PATH does not contain "/bin/". The program executes the attacker's malicious program with the raised privileges....
