CWE-615 通过注释导致的信息暴露

Information Exposure Through Comments

结构: Simple

Abstraction: Variant

状态: Incomplete

被利用可能性: unkown

基本描述

While adding general comments is very useful, some programmers tend to leave important data, such as: filenames related to the web application, old links or links which were not meant to be browsed by users, old code fragments, etc.

扩展描述

An attacker who finds these comments can map the application's structure and files, expose hidden parts of the site, and study the fragments of code to reverse engineer the application, which may help develop further attacks against the site.
