Persistent undocumented backdoor access in Yarbo robot

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.

WattBox 800 & 820 Series < 2.10.0.0 RCE via Diagnostic Endpoints

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.

Enable Telnet via Hidden Functionality in NEC Aterm Devices

Hidden Functionality vulnerability in NEC Platforms, Ltd. Aterm Series allows a attacker to enable telnet via network.

EFM ipTIME A8004T Debug d.cgi httpcon_check_session_url backdoor

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.

Netcore / Netis Routers RCE via UDP Port 53413 Backdoor

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.

Improper Validation of Integrity Check Value vulnerability in Sharp Display Solutions projectors allows a attacker may create and run unauthorized firmware.

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.

Conjure Position Department Service Quality Evaluation System head.php eval backdoor

A vulnerability, which was classified as critical, has been found in Conjure Position Department Service Quality Evaluation System up to 1.0.11. Affected by this issue is the function eval of the file public/assets/less/bootstrap-less/mixins/head.php. The manipulation of the argument payload leads to backdoor. The attack may be launched remotely. The exploit has been disclosed to the public and may be used.

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.

Possibility to generate a session for any user via the "ex:action" parameter after obtaining access to the JWT key

An insufficiently secured internal function allows session generation for arbitrary users. The decodeParam function checks the JWT but does not verify which signing algorithm was used. As a result, an attacker can use the "ex:action" parameter in the VerifyUserByThrustedService function to generate a session for any user.

Undocumented Root Shell Access in SIMCom SIM7600G Modem

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.

PiExtract ｜SOOP-CLM - Hidden Functionality

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.

Hidden Functionality vulnerability in Contec Health CMS8000 Patient Monitor

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.

SICK InspectorP61x, SICK InspectorP62x and SICK TiM3xx are vulnerable for pass-the-hash attacks

The product is vulnerable to pass-the-hash attacks in combination with hardcoded credentials of hidden user levels. This means that an attacker can log in with the hidden user levels and gain full access to the device.

An unintended entry point vulnerability has been identified in certain router models, which may allow for arbitrary command execution. Refer to the ' 01/02/2025 ASUS Router AiCloud vulnerability' section on the ASUS Security Advisory for more information.

A vulnerability has been identified in SENTRON 3KC ATC6 Expansion Module Ethernet (3KC9000-8TL75) (All versions). Affected devices expose an unused, unstable http service at port 80/tcp on the Modbus-TCP Ethernet. This could allow an attacker on the same Modbus network to create a denial of service condition that forces the device to reboot.

NEC Platforms DT900 and DT900S Series 5.0.0.0 – v5.3.4.4, v5.4.0.0 – v5.6.0.20 allows an attacker to access a non-documented the system settings to change settings via local network with unauthenticated user.

Multiple versions of RG-EST300 provided by Ruijie Networks provide SSH server functionality. It is not documented in the manual, and enabled in the initial configuration. Anyone with the knowledge of the related credentials can log in to the affected device, leading to information disclosure, altering the system configurations, or causing a denial of service (DoS) condition.

Hidden functionality issue exists in multiple MFPs provided by Brother Industries, Ltd., which may allow an attacker to obtain the logs of the affected product and obtain sensitive information within the logs.

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.
