|
name: WordPress Redux Framework <=4.2.11 - Information Disclosure
|
|
author: meme-lord
|
|
severity: medium
|
|
description: WordPress Redux Framework plugin through 4.2.11 is susceptible to information disclosure. The plugin registers several unique AJAX actions available to unauthenticated users in the includes function in redux-core/class-redux-core.php. These are predictable, given that they are based on an md5 hash of the site URL with a known salt value of -redux and an md5 hash of the previous hash with a known salt value of -support. An attacker can potentially employ these AJAX actions to retrieve a list of active plugins and their versions, the site's PHP version, and an unsalted md5 hash of the site's AUTH_KEY concatenated with the SECURE_AUTH_KEY.
|
|
remediation: |
|
|
Update WordPress Redux Framework to version 4.2.12 or later.
