Risk Level:
Medium - Spoofed image injection, redirection of uploaded content, remote DoS of Eye-Fi service.

Summary:
The Eye-Fi is an instant solution to add wireless upload capability to any digital camera that supports an SD card. In the version of software tested, the solution has numerous vulnerabilities that can allow unauthorized image uploades to a PC, remotely altering the destination folder, remote crashing of the Eye-Fi service, and more.

Details:

Numerous CSRF attacks that can be launched from a malicious website. These will work as long as the Eye-Fi service is running, which it is by default. These are all possible because the service communicates with the browser via requests to http://localhost:59278.
-CSRF to enable/disable Autostart
-CSRF to enable/disable file upload
-CSRF to change location of file download (default is local system) to remote location via SMB
-CSRF to crash the Eye-Fi service
-CSRF to reconfigure the Eye-Fi card

Weak authentication scheme based on time of day leads to spoofed image uploads.

Spoof Eye-Fi listener on local or remote network.

In addition to these issues, there are several wireless related risks associated with the Eye-Fi sending out probe requests. Using Karma like programs, a rouge
wireless network can be setup, through which the Eye-Fi card will automatically pass
the images, allowing them to be capture.
