Vulnerability from github – Published: 2022-05-24 22:28 – Updated: 2023-07-10 21:30

Details

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.

Severity

5.3 (Medium)
