XSS-to-Root Attack Delivers Malicious Code via Wi-Fi SSID or LoRa Node Name
Security researcher Sasha Romijn demonstrated an XSS attack vector that delivers malicious code over the air through Wi-Fi SSIDs or LoRa node names, exploiting infrastructure web interfaces that render these network identifiers without proper sanitization. The vulnerability is especially dangerous in environments that rely on outdated embedded browsers with infrequent security updates, where a successful injection can escalate from script execution to root access on the underlying device. Defenders should audit management interfaces that display SSID or node name fields, apply input sanitization and output encoding to those components, and update embedded browsers to current versions where patching is available.
