I have found a critical security flaw in the JAWS Screen reader that allows an attacker to gain full system-level access to
the machine. I have tested this on 32-bit Windows Vista
with JAWS 10.0.1154 and 32-bit Windows 7 with JAWS 11.0.611 Beta.
1. From the Windows logon screen with JAWS running, press insert+f2. Run JAWS Manager will appear.
2. Select Settings Packager, and press ok. Settings Packager will open.
3. From Settings Packager, go to File menu > Open, or press ctrl+o.
4. In the open dialog, type “%windir%\system32\*.exe” into the file name field (without the quotes) and press enter.
5. In the list of files, find cmd. Right click on it, or press the applications key and select Run as Administrator.
A system-level command prompt should open. To get out of it, type exit and press enter, then close the Settings Packager.
Update: audio demonstration available here.
