CVE-2022-38094Network attack vector

Authenticated command execution via Telnet injection

Published Sep 8, 2022 · Updated Aug 3, 2024

OS command injection in the Telnet function of Allied Telesis CentreCOM AR260S V2 before 3.3.7 allows remote authenticated users to execute commands. Published advisories do not identify the Telnet command parser, input field, or missing neutralization operation that permits injection. Exploitation requires valid credentials and enabled Telnet, a maintenance-only service disabled by default; arbitrary commands can read or alter data and interrupt routing.
