CVE-2018-11682 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Default and unremovable support credentials allow attackers to gain total super user control of an IoT device through a TELNET session to products using the Stanza 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. EPSS estimates a 4.30% chance of exploitation in the next 30 days.

Description

Default and unremovable support credentials allow attackers to gain total super user control of an IoT device through a TELNET session to products using the Stanza 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
