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 trailing slash ('/multiple/trailing/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.

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.
