Before downloading firmware files, the watch requests <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2024-12367-system-compromise-via-sensitive-information-exposure-in-vega-master-software\/\"  data-wpil-monitor-id=\"89840\">information about the firmware via<\/a> HTTPS from the back-end API. However, the X.509 server <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-6032-unverified-tls-certificate-in-podman-machine-init-command-leads-to-potential-man-in-the-middle-attack\/\"  data-wpil-monitor-id=\"64613\">certificate within the TLS<\/a> handshake is not validated by the device. This leaves room for an attacker, who is in an active machine-in-the-middle position using a <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-6433-critical-tls-certificate-validation-bypass-in-firefox\/\"  data-wpil-monitor-id=\"65337\">TLS proxy and a self-signed certificate<\/a>, to eavesdrop and manipulate the HTTPS communication. Consequently, the attacker can potentially steal the <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-49181-unauthorized-api-endpoint-access-leading-to-denial-of-service-and-data-leakage\/\"  data-wpil-monitor-id=\"61686\">API access<\/a> token of the assigned user account.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-1334712878\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>In essence, the attacker intercepts the communication between the device and server.
