A DLL hijacking vulnerability has been discovered in OutSystems Service Studio 11 11.53.30 build 61739. When a user open a .oml file (OutSystems Modeling Language), the application will load the following DLLs from the same directory av_libGLESv2.dll, libcef.DLL, user32.dll, and d3d10warp.dll. Using a crafted DLL, it is possible to execute arbitrary code in the context of the current logged in user.
