CVE-2018-11681

30
FAUCET Score

CVE-2018-11681 describes a critical vulnerability (CVSS 9.8) affecting Lutron RadioRA 2 and Homeworks QS products, where unremovable default credentials (user:nwk, password:nwk2) allow unauthenticated attackers to gain super user control via TELNET. This flaw, categorized as CWE-798, enables full compromise of the device, despite the vendor's dispute that it only controls lighting and not code execution. While the vulnerability is severe, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
