CVE-2023-22316

Unauthenticated router access via undocumented remote services

Published Jan 17, 2023 · Updated Apr 4, 2025

Hidden functionality in PIXELA PIX-RT100 RT100_TEQ_2.1.1_EQ101 and RT100_TEQ_2.1.2_EQ101 allows attackers to access the router. The firmware exposes undocumented Telnet or SSH services, but PIXELA has not published finer implementation or authentication details. Reachability requires adjacent-network access; published assessments disagree on whether access affects confidentiality alone or also integrity and availability.
