Root command execution via unsanitized AT+MFIP arguments
Published Jun 8, 2025 · Updated Jun 9, 2025
Command injection in Microhard IPn4Gii and Bullet-LTE firmware 0 through 1.2.0-r1132 allows local users to execute commands as root. The cmd_firewall_ip() function in /bin/clitest inserts AT+MFIP fields into a shell command with sprintf and passes the result to popen without neutralizing command-substitution delimiters. A valid device account and access to the restricted CLI over Telnet or SSH are required; successful injection escapes that shell and grants full root-level control.
