CWE-798

Use of a hard-coded cryptographic key pair by the telnetd_startup service allows an attacker on the local area network to obtain a root shell on the device over telnet. The builds of telnetd_startup included in the version 22.5.9.163 of the K2 firmware, and version 32.1.15.93 of the K3C firmware (possibly amongst many other releases) included both the private and public RSA keys. The remaining versions cited here redacted the private key, but left the public key unchanged. An attacker in possession of the leaked private key may, through a scripted exchange of UDP packets, instruct telnetd_startup to spawn an unauthenticated telnet shell as root, by means of which they can then obtain complete control of the device. A consequence of the limited availablility of firmware images for testing is that models and versions not listed here may share this vulnerability.

Axeda agent (All versions) and Axeda Desktop Server for Windows (All versions) uses hard-coded credentials for its UltraVNC installation. Successful exploitation of this vulnerability could allow a remote authenticated attacker to take full remote control of the host operating system.

Home Owners Collection Management System v1.0 was discovered to contain hardcoded credentials which allows attackers to escalate privileges and access the admin panel.

Databasir is a team-oriented relational database model document management platform. Databasir 1.01 has Use of Hard-coded Cryptographic Key vulnerability. An attacker can use hard coding to generate login credentials of any user and log in to the service background located at different IP addresses.

Goldshell ASIC Miners v2.1.x was discovered to contain hardcoded credentials which allow attackers to remotely connect via the SSH protocol (port 22).

Baicells Nova436Q and Neutrino 430 devices with firmware through QRTB 2.7.8 have hardcoded credentials that are easily discovered, and can be used by remote attackers to authenticate via ssh. (The credentials are stored in the firmware, encrypted by the crypt function.)
