IPUX CS7522/CS2330/CS2030 IP Camera Stack Buffer Overflow

IPUX CS7522/CS2330/CS2030 IP Camera Stack Buffer Overflow
Posted Dec 2, 2014
Authored by LiquidWorm | Site zeroscience.mk

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. Versions affected include PT Type ICS2330, Cube Type ICS2030, and Dome Type ICS7522.

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.
