# FlyCms through commit edfdf724 contains a default credentials vulnerability that allows unauthenticated remote…

FlyCms, a PHP content management system, ships with a default super administrator account named flycms with password admin123 through commit edfdf724. An unauthenticated remote attacker can log in at POST /api/auth/login by solving only the image captcha and gets full control of site content, users and configuration.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

Try logging in to the admin login with username flycms and password admin123 on any FlyCms install.

## Fix

Change the flycms account password or disable the account, then move to a FlyCms release after commit edfdf724 that removes the default credential.
