Fortinet Discovers SAP 3D Visual Enterprise Viewer DLL Preloading Vulnerability
Fortinet's FortiGuard Labs has discovered a DLL preloading vulnerability in SAP 3D Visual Enterprise Viewer.
SAP 3D Visual Enterprise Viewer (VEV) is a free 3D visualization viewer for Windows. VEV allows collaboration, analytics, as well as assembly and maintenance work instructions to be delivered in interactive real-time 3D. VEV can run Standalone, in HTML, in MS Office, and or embedded in a variety of SAP Solutions.
SAP 3D Visual Enterprise Viewer 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.
