 XSS and Content Injection in HTC Windows Mobile SMS Preview PopUp
 
 Date: 22.04.2010

-------------------------------------------------------------------

- Description
Windows Mobile shows message previews if configured to do so. Due to missing input validation the contents of a sms is 
not properly sanitized and interpreted as it is. This can lead to content injection and xss.

- Example
Send a sms with the following sample contents to a Windows Mobile based device which has message preview enabled:

1. <html><head><meta http-equiv="refresh" content="0; URL=http://www.google.de/";></head></html>
2. <script>alert('Thats evil')</script>
3. You know waht you can do with that, find your own...

- Tested on
 HTC Touch Pro 2, Windows Mobile 6.5
 Other devices from HTC are vulnerable too

- Solution
Disable the "Show Message" Option in the notification settings, or if the device is from HTC install the supplied patch 
for your device (which does the same).
