Detailsinfo

A vulnerability classified as very critical was found in Lutron radioRA2. Affected by this vulnerability is an unknown code of the component Telnet. The manipulation with an unknown input leads to a hard-coded credentials vulnerability. The CWE definition for the vulnerability is CWE-798. The product contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Default and unremovable support credentials (user:nwk password:nwk2) allow attackers to gain total super user control of an IoT device through a TELNET session to products using the RadioRA 2 Lutron integration protocol Revision M to Revision Y. NOTE: The vendor disputes this id as not being a vulnerability because what can be done through the ports revolve around controlling lighting, not code execution. A certain set of commands are listed, which bear some similarity to code, but they are not arbitrary and do not allow admin-level control of a machine
