Multiple vulnerabilities exist in RaspAP 2.3 to 2.6.5 in the "interface", "ssid" and "wpa_passphrase" POST parameters in /hostapd, when the parameter values contain special characters such as ";" or "$()" which enables an authenticated attacker to execute arbitrary OS commands.
An issue was discovered in includes/webconsole.php in RaspAP 2.5. With authenticated access, an attacker can use a misconfigured (and virtually unrestricted) web console to attack the underlying OS (Raspberry Pi) running this software, and execute commands on the system (including ones for uploading of files and execution of code).
