Recently it was discovered as a part of the research on IoT devices in the most recent firmware for Shekar Endoscope that any malicious user connecting to the device can change the default SSID and password thereby denying the owner an access to his/her own device. This device acts as an Endoscope camera that allows its users to use it in various industrial systems and settings, car garages, and also in some cases in the medical clinics to get access to areas that are difficult for a human being to reach. Any breach of this system can allow an attacker to get access to video feed and pictures viewed by that user and might allow them to get a foot hold in air gapped networks especially in case of nation critical infrastructure/industries. Shekar Endoscope Contains vulnerabilities related to certificate and password management.Information may be tampered with. SHEKARTechnologyEndoscope is a portable endoscope device from SHEKARTechnology, China. There is a security hole in SHEKARTechnologyEndoscope. An attacker could use this vulnerability to modify the default SSID and password, preventing users from accessing the device or causing other hazards. There is a security vulnerability in SHEKAR Technology Endoscope

Recently it was discovered as a part of the research on IoT devices in the most recent firmware for Shekar Endoscope that the desktop application used to connect to the device suffers from a stack overflow if more than 26 characters are passed to it as the Wi-Fi name. This application is installed on the device and an attacker who can provide the right payload can execute code on the user's system directly. Any breach of this system can allow an attacker to get access to all the data that the user has access too. The application uses a dynamic link library(DLL) called "avilib.dll" which is used by the application to send binary packets to the device that allow to control the device. One such action that the DLL provides is change password in the function "sendchangename" which allows a user to change the Wi-Fi name on the device. This function calls a sub function "sub_75876EA0" at address 0x758784F8. The function determines which action to execute based on the parameters sent to it. The "sendchangename" passes the datastring as the second argument which is the name we enter in the textbox and integer 1 as first argument. The rest of the 3 arguments are set to 0. The function "sub_75876EA0" at address 0x75876F19 uses the first argument received and to determine which block to jump to. Since the argument passed is 1, it jumps to 0x75876F20 and proceeds from there to address 0x75876F56 which calculates the length of the data string passed as the first parameter. This length and the first argument are then passed to the address 0x75877001 which calls the memmove function which uses a stack address as the destination where the password typed by us is passed as the source and length calculated above is passed as the number of bytes to copy which leads to a stack overflow. Shekar Endoscope Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. SHEKARTechnologyEndoscope is a portable endoscope device from SHEKARTechnology, China. A buffer overflow vulnerability exists in SHEKARTechnologyEndoscope.

Recently it was discovered as a part of the research on IoT devices in the most recent firmware for Shekar Endoscope that an attacker connected to the device Wi-Fi SSID can exploit a memory corruption issue and execute remote code on the device. This device acts as an Endoscope camera that allows its users to use it in various industrial systems and settings, car garages, and also in some cases in the medical clinics to get access to areas that are difficult for a human being to reach. Any breach of this system can allow an attacker to get access to video feed and pictures viewed by that user and might allow them to get a foot hold in air gapped networks especially in case of nation critical infrastructure/industries. The firmware contains binary uvc_stream that is the UDP daemon which is responsible for handling all the UDP requests that the device receives. The client application sends a UDP request to change the Wi-Fi name which contains the following format: "SETCMD0001+0001+[2 byte length of wifiname]+[Wifiname]. This request is handled by "control_Dev_thread" function which at address "0x00409AE0" compares the incoming request and determines if the 10th byte is 01 and if it is then it redirects to 0x0040A74C which calls the function "setwifiname". The function "setwifiname" uses a memcpy function but uses the length of the payload obtained by using strlen function as the third parameter which is the number of bytes to copy and this allows an attacker to overflow the function and control the $PC value.

Amcrest IPM-721S V2.420.AC00.16.R.20160909 devices mishandle reboots within the past two hours. Amcrest cloud services does not perform a thorough verification when allowing the user to add a new camera to the user's account to ensure that the user actually owns the camera other than knowing the serial number of the camera. This can allow an attacker who knows the serial number to easily add another user's camera to an attacker's cloud account and control it completely. This is possible in case of any camera that is currently not a part of an Amcrest cloud account or has been removed from the user's cloud account. Also, another requirement for a successful attack is that the user should have rebooted the camera in the last two hours. However, both of these conditions are very likely for new cameras that are sold over the Internet at many ecommerce websites or vendors that sell the Amcrest products. The successful attack results in an attacker being able to completely control the camera which includes being able to view and listen on what the camera can see, being able to change the motion detection settings and also be able to turn the camera off without the user being aware of it. Note: The same attack can be executed using the Amcrest Cloud mobile application. Amcrest IPM-721S Devices have vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The Amcrest IPM-721S is a wireless IP camera from Amcrest. An unknown security vulnerability exists in the AmcrestIPM-721SV2.420.AC00.16.R.20160909 release

Amcrest IPM-721S V2.420.AC00.16.R.20160909 devices allow an unauthenticated attacker to download the administrative credentials. If the firmware version V2.420.AC00.16.R 9/9/2016 is dissected using binwalk tool, one obtains a _user-x.squashfs.img.extracted archive which contains the filesystem set up on the device that many of the binaries in the /usr folder. The binary "sonia" is the one that has the vulnerable function that sets up the default credentials on the device. If one opens this binary in IDA-pro one will notice that this follows a ARM little endian format. The function sub_436D6 in IDA pro is identified to be setting up the configuration for the device. If one scrolls to the address 0x000437C2 then one can see that /current_config is being set as an ALIAS for /mnt/mtd/Config folder on the device. If one TELNETs into the device and navigates to /mnt/mtd/Config folder, one can observe that it contains various files such as Account1, Account2, SHAACcount1, etc. This means that if one navigates to http://[IPofcamera]/current_config/Sha1Account1 then one should be able to view the content of the files. The security researchers assumed that this was only possible only after authentication to the device. However, when unauthenticated access tests were performed for the same URL as provided above, it was observed that the device file could be downloaded without any authentication. Amcrest IPM-721S The device contains vulnerabilities related to certificate and password management.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state.

Amcrest IPM-721S V2.420.AC00.16.R.20160909 devices have a timeout policy to wait for 5 minutes in case 30 incorrect password attempts are detected using the Web and HTTP API interface provided by the device. However, if the same brute force attempt is performed using the ONVIF specification (which is supported by the same binary) then there is no account lockout or timeout executed. This can allow an attacker to circumvent the account protection mechanism and brute force the credentials. If the firmware version V2.420.AC00.16.R 9/9/2016 is dissected using binwalk tool, one obtains a _user-x.squashfs.img.extracted archive which contains the filesystem set up on the device that many of the binaries in the /usr folder. The binary "sonia" is the one that has the vulnerable function that performs the credential check in the binary for the ONVIF specification. If one opens this binary in IDA-pro one will notice that this follows a ARM little endian format. The function at address 00671618 in IDA pro is parses the WSSE security token header. The sub_ 603D8 then performs the authentication check and if it is incorrect passes to the function sub_59F4C which prints the value "Sender not authorized.".

If the firmware version V2.420.AC00.16.R 9/9/2016 is dissected using binwalk tool, one obtains a _user-x.squashfs.img.extracted archive which contains the filesystem set up on the device that many of the binaries in the /usr folder. The binary "sonia" is the one that has the vulnerable function that sets up the default credentials on the device. If one opens this binary in IDA-pro, one will notice that this follows a ARM little endian format. The function sub_3DB2FC in IDA pro is identified to be setting up the values at address 0x003DB5A6. The sub_5C057C then sets this value and adds it to the Configuration files in /mnt/mtd/Config/Account1 file. Amcrest IPM-721S The device contains a vulnerability related to the use of hard-coded credentials.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The Amcrest IPM-721S is a wireless IP camera from Amcrest. An authorization issue vulnerability exists in the AmcrestIPM-721SV2.420.AC00.16.R.20160909 release. The vulnerability stems from a lack of authentication in the network system or product or insufficient strength of authentication. No detailed vulnerability details are currently available.

Attackers can use default passwords or hard-coded passwords, hard-coded certificates, etc. to attack affected components

On Amcrest IPM-721S V2.420.AC00.16.R.20160909 devices, the users on the device are divided into 2 groups "admin" and "user". However, as a part of security analysis it was identified that a low privileged user who belongs to the "user" group and who has access to login in to the web administrative interface of the device can add a new administrative user to the interface using HTTP APIs provided by the device and perform all the actions as an administrative user by using that account. If the firmware version V2.420.AC00.16.R 9/9/2016 is dissected using binwalk tool, one obtains a _user-x.squashfs.img.extracted archive which contains the filesystem set up on the device that many of the binaries in the /usr folder. The binary "sonia" is the one that has the vulnerable functions that performs the various action described in HTTP APIs. If one opens this binary in IDA-pro one will notice that this follows a ARM little endian format. The function at address 0x00429084 in IDA pro is the one that processes the HTTP API request for "addUser" action. If one traces the calls to this function, it can be clearly seen that the function sub_ 41F38C at address 0x0041F588 parses the call received from the browser and passes it to the "addUser" function without any authorization check. Amcrest IPM-721S Devices have vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state.

An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device runs a custom daemon on UDP port 5978 which is called "dldps2121" and listens for broadcast packets sent on 255.255.255.255. This daemon handles custom D-Link UDP based protocol that allows D-Link mobile applications and desktop applications to discover D-Link devices on the local network. The binary processes the received UDP packets sent from any device in "main" function. One path in the function traverses towards a block of code that handles commands to be executed on the device. The custom protocol created by D-Link follows the following pattern: Packetlen, Type of packet; M=MAC address of device or broadcast; D=Device Type;C=base64 encoded command string;test=1111. If a packet is received with the packet type being "S" or 0x53 then the string passed in the "C" parameter is base64 decoded and then executed by passing into a System API. We can see at address 0x00009B44 that the string received in packet type subtracts 0x31 or "1" from the packet type and is compared against 0x22 or "double quotes". If that is the case, then the packet is sent towards the block of code that executes a command. Then the value stored in "C" parameter is extracted at address 0x0000A1B0. Finally, the string received is base 64 decoded and passed on to the system API at address 0x0000A2A8 as shown below. The same form of communication can be initiated by any process including an attacker process on the mobile phone or the desktop and this allows a third-party application on the device to execute commands on the device without any authentication by sending just 1 UDP packet with custom base64 encoding. D-Link DCS-1100 and DCS-1130 The device contains a command injection vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state.

An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device requires that a user logging into the device provide a username and password. However, the device allows D-Link apps on the mobile devices and desktop to communicate with the device without any authentication. As a part of that communication, the device uses custom version of base64 encoding to pass data back and forth between the apps and the device. However, the same form of communication can be initiated by any process including an attacker process on the mobile phone or the desktop and this allows a third party to retrieve the device's password without any authentication by sending just 1 UDP packet with custom base64 encoding. The severity of this attack is enlarged by the fact that there more than 100,000 D-Link devices out there. D-Link DCS-1100 and DCS-1130 The device contains a certificate / password management vulnerability.Information is acquired, information is falsified, and denial of service (DoS) May be in a state.
