CWE-53 路径等价:'\multiple\internal\backslash'

Path Equivalence: '\multiple\internal\backslash'

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 backslash ('\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.
