CVE-2023-6317Network attack vector

Privileged account creation via cross-profile client key

Published Apr 9, 2024 · Updated Aug 2, 2024

Authorization bypass in LG Electronics webOS 4 through 7 allows remote attackers to create a privileged account without a TV PIN. The secondscreen.gateway account handler sets skipPrompt when a supplied companion-client-key matches any existing profile, but it does not verify that the key belongs to the account requesting elevated permissions. Network access to the service on TCP ports 3000 or 3001 is sufficient; the new profile can access protected SSAP APIs, but this flaw alone does not grant root execution.
