Detailsinfo

A vulnerability has been found in cerebrate up to 1.36 and classified as critical. Affected by this vulnerability is the function add. The manipulation of the argument params with an unknown input leads to a dynamically-determined object attributes vulnerability. The CWE definition for the vulnerability is CWE-915. The product receives input from an upstream component that specifies multiple attributes, properties, or fields that are to be initialized or updated in an object, but it does not properly control which attributes can be modified. As an impact it is known to affect integrity, and availability. The summary by CVE is:

Cerebrate before version 1.37 contains a mass-assignment vulnerability in the generic CRUD add path. The add() handler attempted to remove an attacker-supplied id from $params before normalizing the request through __massageInput(). Because the normalized $input could still contain an id field, a user able to reach an affected add endpoint could supply an identifier that should have been server-controlled. Successful exploitation could allow creation of objects with attacker-chosen identifiers, potentially causing unauthorized data manipulation, object spoofing, inconsistent references, or disruption through identifier collisions, depending on the affected model and endpoint permissions. The issue was fixed in v1.37 by removing id from the normalized input before entity patching.
