CVSS v3.1 |
| A hidden, persistent backdoor was found in Yarbo firmware v2.3.9 that provides remote, unauthenticated (or weakly authenticated) access to privileged functionality. The backdoor is undocumented, cannot be disabled via user-facing settings, and survives factory reset and ordinary firmware updates. |
| Delta Electronics AS320T has denial of service via the undocumented subfunction vulnerability. |
| Hidden functionality in the /goform/setSysTools endpoint in Nexxt Solutions Nebula 300+ firmware through version 12.01.01.37 allows remote enablement of a Telnet service. By sending a crafted POST request with parameters such as telnetManageEn=true and telnetPwd, an authenticated attacker can activate a Telnet service on port 23. This exposes a privileged diagnostic interface that is not intended for external access and can be used to interact with the underlying system. |
| Snap One WattBox 800 and 820 series firmware versions prior to 2.10.0.0 contain undisclosed diagnostic HTTP endpoints that require only the device MAC address and service tag for authentication, both of which are printed in plaintext on the physical device label. Attackers with access to the device label or documentation containing these values can authenticate to the several endpoints and execute arbitrary commands as root on the device. |
| Hidden Functionality vulnerability in NEC Platforms, Ltd. Aterm Series allows a attacker to enable telnet via network. |
| A vulnerability was determined in EFM ipTIME A8004T 14.18.2. Affected is the function httpcon_check_session_url of the file /sess-bin/d.cgi of the component Debug Interface. This manipulation of the argument cmd causes backdoor. It is possible to initiate the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way. |
| Hidden functionality issue exists in WRC-BE36QS-B and WRC-W701-B. If exploited, the product's hidden debug function may be enabled by a remote attacker who can log in to WebGUI. |
| Mercku M6a devices through 2.1.0 allow TELNET sessions via a router.telnet.enabled.update request by an administrator. |
| Multiple Elber products suffer from an unauthenticated device configuration and client-side hidden functionality disclosure. |
| The "monitor" binary in the firmware of the affected product attempts to mount to a hard-coded, routable IP address, bypassing existing device network settings to do so. The function also enables the network interface of the device if it is disabled. The function is triggered by attempting to update the device from the user menu. This could serve as a backdoor to the device, and could lead to a malicious actor being able to upload and overwrite files on the device. |
| Hidden functionality issue exists in WN-7D36QR and WN-7D36QR/UE. If this vulnerability is exploited, SSH may be enabled by a remote authenticated attacker. |
| Longse model LBH30FE200W cameras, as well as products based on this device, provide an unrestricted access for an attacker located in the same local network to an undocumented binary service CoolView on one of the ports.
An attacker with a knowledge of the available commands is able to perform read/write operations on the device's memory, which might result in e.g. bypassing telnet login and obtaining full access to the device. |
| A remote code execution vulnerability exists in multiple Netcore and Netis routers models with firmware released prior to August 2014 due to the presence of an undocumented backdoor listener on UDP port 53413. Exact version boundaries remain undocumented. An unauthenticated remote attacker can send specially crafted UDP packets to execute arbitrary commands on the affected device. This backdoor uses a hardcoded authentication mechanism and accepts shell commands post-authentication. Some device models include a non-standard implementation of the `echo` command, which may affect exploitability. |
| MinMax CMS from MinMax Digital Technology contains a hidden administrator account with a fixed password that cannot be removed or disabled from the management interface. Remote attackers who obtain this account can bypass IP access control restrictions and log in to the backend system without being recorded in the system logs. |
| An OpenSSH daemon listens on TCP port 22. There is a hard-coded entry in the "/etc/shadow" file in the firmware image for the "root" user. However, in the default SSH configuration the "PermitRootLogin" is disabled, preventing the root user from logging in via SSH. This configuration can be bypassed/changed by an attacker through multiple paths though. |
| Hidden functionality issue in multiple digital video recorders provided by TAKENAKA ENGINEERING CO., LTD. allows a remote authenticated attacker to execute an arbitrary OS command on the device or alter the device settings. |
| The "update" binary in the firmware of the affected product sends attempts to mount to a hard-coded, routable IP address, bypassing existing device network settings to do so. The function triggers if the 'C' button is pressed at a specific time during the boot process. If an attacker is able to control or impersonate this IP address, they could upload and overwrite files on the device. |
| The SIMCom SIM7600G modem supports an undocumented AT command, which allows an attacker to execute system commands with root permission on the modem. An attacker needs either physical access or remote shell access to a device that interacts directly with the modem via AT commands. |
| SOOP-CLM developed by PiExtract has a Hidden Functionality vulnerability, allowing privileged remote attackers to exploit a hidden functionality to execute arbitrary code on the server. |
| Certain models of D-Link wireless routers contain an undisclosed factory testing backdoor. Unauthenticated attackers on the local area network can force the device to enable Telnet service by accessing a specific URL and can log in by using the administrator credentials obtained from analyzing the firmware. |
