Krayin CRM 2.2.4 contains a missing authentication vulnerability in the installer middleware that allows unauthenticated remote attackers to overwrite the primary administrator account by sending a crafted HTTP POST request with the X-Requested-With: XMLHttpRequest header to bypass the CanInstall middleware redirect check. Attackers can supply arbitrary name, email, and password values to the admin-config-setup endpoint, which performs an unauthenticated updateOrInsert targeting the hardcoded administrator user ID, enabling full administrative access to all CRM data.
