CWE-72 Apple HFS+交换数据流路径处理不恰当

Improper Handling of Apple HFS+ Alternate Data Stream Path

结构: Simple

Abstraction: Variant

状态: Incomplete

被利用可能性: unkown

基本描述

The software does not properly handle special paths that may identify the data or resource fork of a file on the HFS+ file system.

扩展描述

If the software chooses actions to take based on the file name, then if an attacker provides the data or resource fork, the software may take unexpected actions. Further, if the software intends to restrict access to a file, then an attacker might still be able to bypass intended access restrictions by requesting the data or resource fork for that file.

示例代码

例

A web server that interprets FILE.cgi as processing instructions could disclose the source code for FILE.cgi by requesting FILE.cgi/..namedfork/data. This might occur because the web server invokes the default handler which may return the contents of the file.

Notes

Theoretical
This and similar problems exist because the same resource can have multiple identifiers that dictate which behavior can be performed on the resource.
Research Gap
Under-studied
