An authorization bypass vulnerability was found in Ceph versions 15.2.0 before 15.2.2, where the ceph-mon and ceph-mgr daemons do not properly restrict access, resulting in gaining access to unauthorized resources. This flaw allows an authenticated client to modify the configuration and possibly conduct further attacks.

CVSS 2.0 Base Score 5.2. CVSS Attack Vector: adjacent_network. CVSS Attack Complexity: low. CVSS Vector: (AV:A/AC:L/Au:S/C:P/I:P/A:P).
The following code could be for a medical records application. It displays a record to already authenticated users, confirming the user's authorization using a value stored in a cookie.
}}setcookie("role", $role, time()+60*60*2);die("\n");DisplayMedicalHistory($_POST['patient_ID']);die("You are not Authorized to view this record\n");The programmer expects that the cookie will only be set when getRole() succeeds. The programmer even diligently specifies a 2-hour expiration for the cookie. However, the attacker can easily set the "role" cookie to the value "Reader". As a result, the $role variable is "Reader", and getRole() is never invoked. The attacker has bypassed the authorization system.
