Fortinet Discovers Samsung SMART Signage TV MagicInfo Express DLL Pre-Loading Vulnerability
Fortinet's FortiGuard Labs has discovered a DLL preloading vulnerability in Samsung SMART Signage TV MagicInfo Express.
Samsung SMART Signage TV MagicInfo Express is an intuitive content creation software that makes it easy to design and launch your own promotional campaigns. With the click of a few buttons on mobile device or desktop, you can quickly load, update, edit and deploy your promotional content using your Wi-Fi network or USB.
Samsung SMART Signage TV MagicInfo Express for Windows is susceptible to a DLL preloading vulnerability. The issue occurs when the application looks to load a DLL for execution and an attacker provides a malicious DLL to use instead. The application generally follows a specific search path to locate the DLL. The vulnerability can be exploited by a simple file write (or potentially an over-write) which results in a foreign DLL running under the context of the application.
