Vulnerabilities

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.

Recently it was discovered as a part of the research on IoT devices in the most recent firmware for Shekar Endoscope that the device has Telnet functionality enabled by default. 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.

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.

Recently it was discovered as a part of the research on IoT devices in the most recent firmware for Shekar Endoscope that the device has default Wi-Fi credentials that are exactly the same for every 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.

An exploitable arbitrary memory read vulnerability exists in the KCodes NetUSB.ko kernel module which enables the ReadySHARE Printer functionality of at least two NETGEAR Nighthawk Routers and potentially several other vendors/products. A specially crafted index value can cause an invalid memory read, resulting in a denial of service or remote information disclosure. An unauthenticated attacker can send a crafted packet on the local network to trigger this vulnerability.

An exploitable information disclosure vulnerability exists in the KCodes NetUSB.ko kernel module that enables the ReadySHARE Printer functionality of at least two NETGEAR Nighthawk Routers and potentially several other vendors/products. An unauthenticated, remote attacker can craft and send a packet containing an opcode that will trigger the kernel module to return several addresses. One of which can be used to calculate the dynamic base address of the module for further exploitation.

An issue was discovered on Vera VeraEdge 1.7.19 and Veralite 1.7.481 devices. The device provides UPnP services that are available on port 3480 and can also be accessed via port 80 using the url "/port_3480". It seems that the UPnP services provide "request_image" as one of the service actions for a normal user to retrieve an image from a camera that is controlled by the controller. It seems that the "res" (resolution) parameter passed in the query string is not sanitized and is stored on the stack which allows an attacker to overflow the buffer. The function "LU::Generic_IP_Camera_Manager::REQ_Image" is activated when the lu_request_image is passed as the "id" parameter in the query string. This function then calls "LU::Generic_IP_Camera_Manager::GetUrlFromArguments". This function retrieves all the parameters passed in the query string including "res" and then uses the value passed in it to fill up buffer using the sprintf function. However, the function in this case lacks a simple length check and as a result an attacker who is able to send more than 184 characters can easily overflow the values stored on the stack including the $RA value and thus execute code on the device.

It seems that the UPnP services provide "request_image" as one of the service actions for a normal user to retrieve an image from a camera that is controlled by the controller. It seems that the "URL" parameter passed in the query string is not sanitized and is stored on the stack which allows an attacker to overflow the buffer. The function "LU::Generic_IP_Camera_Manager::REQ_Image" is activated when the lu_request_image is passed as the "id" parameter in query string. This function then calls "LU::Generic_IP_Camera_Manager::GetUrlFromArguments" and passes a "pointer" to the function where it will be allowed to store the value from the URL parameter. This pointer is passed as the second parameter $a2 to the function "LU::Generic_IP_Camera_Manager::GetUrlFromArguments". However, neither the callee or the caller in this case performs a simple length check and as a result an attacker who is able to send more than 1336 characters can easily overflow the values stored on the stack including the $RA value and thus execute code on the device.

OPNsense 18.7.x before 18.7.7 has Incorrect Access Control.

An issue was discovered in RubyGems 2.6 and later through 3.0.2. Gem::GemcutterUtilities#with_response may output the API response to stdout as it is. Therefore, if the API side modifies the response, escape sequence injection may occur.

An issue was discovered in RubyGems 2.6 and later through 3.0.2. The gem owner command outputs the contents of the API response directly to stdout. Therefore, if the response is crafted, escape sequence injection may occur.

An issue was discovered in RubyGems 2.6 and later through 3.0.2. Since Gem::UserInteraction#verbose calls say without escaping, escape sequence injection is possible.
