Alberto Moreno Tablado has reported a vulnerability in multiple HTC products, which can be exploited by malicious users to disclose sensitive information and bypass certain security restrictions.
The vulnerability is caused due to an input validation error in the Bluetooth OBEX FTP server (obexfile.dll). This can be exploited to download or upload arbitrary files outside the root directory via directory traversal attacks.
Successful exploitation requires OBEX read or write access.
The vulnerability is reported in the following products and versions:
* HTC P3650 (OS version 5.2.19965)
* HTC P3600 (OS version 5.2.1933)
* HTC S710 (OS version 5.2.1235)
* HTC S740 (OS version 5.2.20279)
* HTC TOUCH DIAMOND (OS version 5.2.20275)
* HTC TOUCH PRO (OS version 5.2.19965)
* HTC TOUCH CRUISE (OS version 5.2.20765)
* HTC TOUCH FIND (OS version 5.2.1623)
Other HTC devices running Professional or Standard versions of Windows Mobile 6 or 6.1 may also be affected.
