CWE-42 路径等价：'filename.' (尾部点号)

Path Equivalence: 'filename.' (Trailing Dot)

结构: Simple

Abstraction: Variant

状态: Incomplete

被利用可能性: unkown

基本描述

A software system that accepts path input in the form of trailing dot ('filedir.') without appropriate validation can lead to ambiguous path resolution and allow an attacker to traverse the file system to unintended locations or access arbitrary files.
