问题描述

WordPress 的 WP Guru 错误日志查看器插件在 1.0.1.3 及之前的所有版本中都容易受到通过 wp_ajax_nopriv_elvwp_log_download AJAX 操作进行任意文件读取的攻击。这使得未经身份验证的攻击者可以读取服务器上任意文件的内容，其中可能包含敏感信息。

info:
  name: Error Log Viewer By WP Guru <= 1.0.1.3 - Missing Authorization to Arbitrary File Read
  author: s4e-io
  severity: high
  description: |
    The Error Log Viewer By WP Guru plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 1.0.1.3 via the wp_ajax_nopriv_elvwp_log_download AJAX action. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information.
