Technical details

The ioos web backend (/bin/ioos) running as root fails to sanitize the group_name parameter before embedding it into a uci shell command passed to system(). An attacker can break out of the single-quoted string context with a payload like a';CMD;' to inject arbitrary OS commands executing with root privileges. The vulnerability is reachable either via the localhost trust mechanism (127.0.0.1) or with a valid session token, which on default configurations can be obtained with an empty password.
