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. ---------------------------------------------------------------------------------- (3ef0.3e0c): Access violation - code c0000005 (first chance) First chance exceptions are reported before any exception handling.
