An issue was discovered in Bitrix24 Bitrix Framework (1c site management) 20.0. An "User enumeration and Improper Restriction of Excessive Authentication Attempts" vulnerability exists in the admin login form, allowing a remote user to enumerate users in the administrator group. This also allows brute-force attacks on the passwords of users not in the administrator group.
The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.
