Summary

phpMyAdmin through 5.2.3 does not require re-authentication before changing two-factor authentication settings (CWE-620). An authenticated attacker holding a hijacked session can post the 2fa key to /config/set to remove two-factor authentication, so later logins need only the MySQL password. An exploit is linked in the references.

Description from the CNA

phpMyAdmin through 5.2.3 contains a missing re-authentication vulnerability that allows authenticated attackers to remove two-factor authentication by posting the 2fa key to /config/set. Attackers holding a hijacked session can submit key=2fa with a null JSON value to SetConfigController, stripping 2FA so later logins require only the MySQL password.
