CWE-403 将文件描述符暴露给不受控制的范围(文件描述符泄露)

Exposure of File Descriptor to Unintended Control Sphere ('File Descriptor Leak')

结构: Simple

Abstraction: Base

状态: Draft

被利用可能性: unkown


A process does not close sensitive file descriptors before invoking a child process, which allows the child to perform unauthorized I/O operations using those descriptors.


When a new process is forked or executed, the child process inherits any open file descriptors. When the child process has fewer privileges than the parent process, this might introduce a vulnerability if the child process can access the file descriptor but does not have the privileges to access the associated file.
