HTC Android Vulnerability - Exposes Phone numbers, Gps, SMS, Emails etc


If you are running a HTC Android smartphone with the latest updates applied, chances are your personal data is freely accessible to any app you have given network access to in the form of full Internet permissions.This vulnerability isn’t a backdoor or some inherent flaw in Android, it is instead HTC failing to lock down its data sharing policies used in the Tell HTC software users have to allow or disallow on their phone. The problem being, not only is your data vulnerable when Tell HTC is turned on, it’s just as vulnerable when it is turned off.

In brief, any app on affected devices that requests a single android.permission.INTERNET (which is normal for any app that connects to the web or shows ads) can get its hands on:
  • the list of user accounts, including email addresses and sync status for each
  • last known network and GPS locations and a limited previous history of locations
  • phone numbers from the phone log
  • SMS data, including phone numbers and encoded text (not sure yet if it's possible to decode it, but very likely)
  • system logs (both kernel/dmesg and app/logcat), which includes everything your running apps do and is likely to include email addresses, phone numbers, and other private info
But that's not all. After looking at the huge amount of data (the log file was 3.5MB on my EVO 3D) that is vulnerable to apps exploiting this vulnerability all day, I found the following is also exposed:
  • active notifications in the notification bar, including notification text
  • build number, bootloader version, radio version, kernel version
  • network info, including IP addresses
  • full memory info
  • CPU info
  • file system info and free space on each partition
  • running processes
  • current snapshot/stacktrace of not only every running process but every running thread
  • list of installed apps, including permissions used, user ids, versions, and more
  • system properties/variables
  • currently active broadcast listeners and history of past broadcasts received
  • currently active content providers
  • battery info and status, including charging/wake lock history
  • and more
Quite simply put these are HUGE vulnerabilities that people need to be aware of.  This problem is only effecting stock roms so if you are rooted you have no cause for alarm.
