Authenticated command execution via unsanitized ping host
Published Jan 6, 2023 · Updated Apr 9, 2025
OS command injection in Nexxt Amp300 ARN02304U8 firmware 42.103.1.5095 and 80.103.2.5045 allows remote authenticated users to execute commands. The goform/sysTools ping handler places the JSON host value into an operating-system command without neutralizing shell metacharacters, so &telnetd starts a Telnet daemon. Access to the authenticated web-management interface is required, and successful exploitation runs attacker-chosen commands on the router.
