Symantec Vulnerability Research http://www.symantec.com/research Security Advisory Palm OS Treo smartphones are equipped with a system password lock to secure contents of handheld data from unauthorized access. When this lock is engaged, Treo's built-in Find feature is still accessible and can be used to perform searches on text in Treo applications and databases (e.g. SMS Messages, Memos, Calendar, Tasks, etc). Search results are accessible, and depending on their size, may be truncated. An attacker may use this vulnerability to retrieve information from a locked device. The built-in Find feature can also be used to access an Edit window and paste previously cut or copied data into the search field of a locked device. An attacker may use this vulnerability to view data that was cut or copied from Treo applications prior to the device being locked. Details: The Find feature can be accessed when the handheld is locked by issuing keyboard shortcut keys on the Emergency Call screen and the Call In Progress screen that is displayed when an incoming call is accepted. More details for each of these methods is listed below. 1. Emergency Call Screen - From the System Lockout screen, select 'Make Emergency Call'. Press the keyboard shortcut keys for Find (Option Key + Find Key). This will open the Find window on the bottom half of the screen. Enter the desired text to search and click on 'OK'. (Searching on a single space usually returns data) To access the Edit window, press the Menu key while the Find window is open. Select Paste from the Edit window to paste previously cut or copied data in the Find window. 2. Call In Progress screen Accept an incoming call. Press the keyboard shortcut keys for Find (Option Key + Find Key) during the call. This will open the Find window on the bottom half of the screen. Enter the desired text to search and click on 'OK'. (Searching on a single space usually returns data) To access the Edit window, press the Menu key while the Find window is open. Select Paste from the Edit window to paste previously cut or copied data in the Find window. Note: The Find window will stay open after a call has been disconnected. However, users will be returned to the Lockout screen when the find results are closed. The following devices are known to be affected: - Cingular Treo 650: Treo650-1.03a-VZW and Treo650-1.12-SPCS - Cingular Treo 680 - Sprint/Verizon Treo 700p Other versions of Treo smartphones are also likely affected. http://discussion.treocentral.com/showthread.php?p=1199445&posted=1#post
