Untrusted search path vulnerability in the installers of multiple SEIKO EPSON products allows an attacker to gain privileges via a Trojan horse DLL in an unspecified directory.

Peplink Balance before 8.1.0rc1 allows an unauthenticated attacker to download PHP configuration files (/filemanager/php/connector.php) from Web Admin.

/usr/lib/lua/luci/controller/admin/autoupgrade.lua on PHICOMM K2(PSG1218) V22.5.9.163 devices allows remote authenticated users to execute any command via shell metacharacters in the cgi-bin/luci autoUpTime parameter.

On Coldcard MK1 and MK2 devices, a side channel for the row-based OLED display was found. The power consumption of each row-based display cycle depends on the number of illuminated pixels, allowing a partial recovery of display contents. For example, a hardware implant in the USB cable might be able to leverage this behavior to recover confidential secrets such as the PIN and BIP39 mnemonic. In other words, the side channel is relevant only if the attacker has enough control over the device's USB connection to make power-consumption measurements at a time when secret data is displayed. The side channel is not relevant in other circumstances, such as a stolen device that is not currently displaying secret data. On Coldcard MK1 and MK2 devices, a side channel for the row-based OLED display was found. The power consumption of each row-based display cycle depends on the number of illuminated pixels, allowing a partial recovery of display contents. For example, a hardware implant in the US…

In IP-AK2 Access Control Panel Version 1.04.07 and prior, the integrated web server of the affected devices could allow remote attackers to obtain web configuration data, which can be accessed without authentication over the network.

An issue was discovered on the ENTTEC Datagate MK2, Storm 24, Pixelator, and E-Streamer MK2 with firmware 70044_update_05032019-482. They include a hard-coded SSH backdoor for remote SSH and SCP access as the root user. A command in the relocate and relocate_revB scripts copies the hardcoded key to the root user's authorized_keys file, enabling anyone with the associated private key to gain remote root access to all affected products.

An issue was discovered on the ENTTEC Datagate MK2, Storm 24, Pixelator, and E-Streamer MK2 with firmware 70044_update_05032019-482. They allow high-privileged root access by www-data via sudo without requiring appropriate access control. (Furthermore, the user account that controls the web application service is granted full access to run any system commands with elevated privilege, without the need for password authentication. Should vulnerabilities be identified and exploited within the web application, it may be possible for a threat actor to create or run high-privileged binaries or executables that are available within the operating system of the device.)

An issue was discovered on the ENTTEC Datagate MK2, Storm 24, Pixelator, and E-Streamer MK2 with firmware 70044_update_05032019-482. They replace secure and protected directory permissions (set as default by the underlying operating system) with highly insecure read, write, and execute directory permissions for all users. By default, /usr/local and all of its subdirectories should have permissions set to only allow non-privileged users to read and execute from the tree structure, and to deny users from creating or editing files in this location. The ENTTEC firmware startup script permits all users to read, write, and execute (rwxrwxrwx) from the /usr, /usr/local, /usr/local/dmxis, and /usr/local/bin/ directories.

A number of stored XSS vulnerabilities have been identified in the web configuration feature in ENTTEC Datagate Mk2 70044_update_05032019-482 that could allow an unauthenticated threat actor to inject malicious code directly into the application. This affects, for example, the Profile Description field in JSON data to the Profile Editor.

ENTTEC Datagate MK2, Storm 24, Pixelator all firmware versions prior to (70044,70050,70060)_update_05032019-482 allows an unauthenticated user to initiate a remote reboot, which may be used to cause a denial of service condition.
