SeaConnect 370W v1.3.34. The HandleIncomingSeaCloudMessage function uses at [4] the json_object_get_string to populate the p_payload global variable. The p_payload is only 0x100 bytes long, and the total MQTT message could be up to 0x201 bytes. Because the function json_object_get_string will fill str based on the length of the json\u00e2\u20ac\u2122s value and not the actual str size, this would result in a possible out-of-bounds write.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2022-02-05T02:45:30.000000Z"} 2022-02-05T02:45:30+00:00
