CVE-2026-58454

JAIOTlink C492A-W6 Wi-Fi IP cameras running firmware 4.8.30.57701411 contain a remote code execution vulnerability that allows authenticated attackers to execute arbitrary shell scripts by writing to the writable persistent JFFS2 storage path and triggering execution through the authenticated HTTP endpoint. Attackers can stage a malicious script in the writable persistent storage and request the config endpoint to invoke it via popen(), achieving persistent remote code execution that survives device reboots.
