Description
The Gutenberg Template Library & Redux Framework plugin <= 4.2.11 for WordPress registered several AJAX actions available to unauthenticated users in the `includes` function in `redux-core/class-redux-core.php` that were unique to a given site but deterministic and predictable given that they were 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'. These AJAX actions could be used to retrieve a list of active plugins and their versions, the site's PHP version, and an unsalted md5 hash of site’s `AUTH_KEY` concatenated with the `SECURE_AUTH_KEY`.
Available Exploits
WordPress Redux Framework <=4.2.11 - Information Disclosure
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.
