Air Transfer cross site scripting

Vulnerability

The Air Transfer iOS application versions 1.0.14 and 1.2.1 contain a reflected cross-site scripting (XSS) vulnerability. The exact parameter is undisclosed, but the application fails to properly sanitize user input before reflecting it in the response, allowing arbitrary JavaScript injection [1].

Exploitation

An attacker can exploit this vulnerability by crafting a malicious URL containing the XSS payload and luring a victim to click it. The victim must be browsing the Air Transfer web interface over the local WiFi network. No authentication is required [1].

Impact

Successful exploitation allows the attacker to execute arbitrary JavaScript in the context of the victim's browser session. This can lead to session hijacking, data theft, or actions performed on behalf of the victim [1].

Mitigation

No official patch or fixed version has been disclosed by the vendor. As of the advisory publication date (2017-02-22), users are advised to exercise caution when accessing the Air Transfer web interface and to consider alternative applications if possible [1].
