Root command execution via AT+MFMAC argument injection
Published Jun 8, 2025 · Updated Jun 9, 2025
Command injection in Microhard IPn4Gii / Bullet-LTE Firmware 1.2.0-r1132 and earlier allows local users to execute commands as root. The cmd_firewall_mac function inserts an AT+MFMAC argument into a shell command string passed to popen without neutralizing $() or backticks. A valid device account and restricted CLI access through Telnet or SSH are required; successful injection escapes the restricted shell and grants full root-level device control.
