Detailsinfo

A vulnerability classified as problematic has been found in Moxa MXsecurity up to 2.3.0. This affects an unknown part of the file /api/v1/devices/register of the component JSON Handler. The manipulation with an unknown input leads to a dynamically-determined object attributes vulnerability. CWE is classifying the issue as 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. This is going to have an impact on integrity. The summary by CVE is:

An unauthenticated device registration vulnerability, caused by Improperly Controlled Modification of Dynamically-Determined Object Attributes, has been identified in the MXsecurity Series. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted JSON payload to the device's registration endpoint /api/v1/devices/register, allowing the attacker to register unauthorized devices without authentication. Although exploiting this vulnerability has limited modification of data, there is no impact to the confidentiality and availability of the affected device, as well as no loss of confidentiality, integrity, and availability within any subsequent systems.
