Memory corruption via unsafe testWifiAP logging
Published Oct 25, 2022 · Updated Apr 15, 2025
Format string injection in Abode iota All-In-One Security Kit 6.9X and 6.9Z allows remote attackers to corrupt memory via XCMD. The testWifiAP handler embeds attacker-controlled default_key_id and key values in a command buffer, then passes that buffer as the format argument to log. Exploitation requires changing a Wi-Fi configuration value and invoking testWifiAP; crafted format directives expose or corrupt process memory and interrupt service.
