CWE-51 路径等价：'/multiple//internal/slash'
Path Equivalence: '/multiple//internal/slash'
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 multiple internal slash ('/multiple//internal/slash/') 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.

可能的缓解方案
MIT-20 Implementation
策略: Input Validation
Inputs 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 whitelist validation schemes by introducing dangerous inputs after they have been checked.
