An issue exists in pson EH-TW5350 Epson iProjection.apk v3.2.6. If you identify a projector equipped with an iProjection function, you can access the projector using hard-coded authentication information and control the projector maliciously.

In Epson iProjection v2.30, the driver file EMP_MPAU.sys allows local users to cause a denial of service (BSOD) or possibly have unspecified other impact because of not validating input values from IOCtl 0x9C402406 and IOCtl 0x9C40240A. (0x9C402402 has only a NULL pointer dereference.) This affects \Device\EMPMPAUIO and \DosDevices\EMPMPAU.

In Epson iProjection v2.30, the driver file (EMP_NSAU.sys) allows local users to cause a denial of service (BSOD) via crafted input to the virtual audio device driver with IOCTL 0x9C402402, 0x9C402406, or 0x9C40240A. \Device\EMPNSAUIO and \DosDevices\EMPNSAU are similarly affected.
