D-Link DCS-8300LHV2 ONVIF Hardcoded PIN Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DCS-8300LHV2 IP cameras. Authentication is not required to exploit this vulnerability. The specific flaw exists within the configuration of the ONVIF API. The issue results from the use of a hardcoded PIN. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-21492.

The Android Client application, when enrolled to the AppHub server, connects to an MQTT broker to exchange messages and receive commands to execute on the HMI device. The protocol builds on top of MQTT to implement the remote management of the device is encrypted with a hard-coded DES symmetric key, that can be retrieved reversing both the Android Client application and the server-side web application. This issue allows an attacker able to control a malicious MQTT broker on the same subnet network of the device, to craft malicious messages and send them to the HMI device, executing arbitrary commands on the device itself.

Hard-coded credentials in Juplink RX4-1500 versions V1.0.2 through V1.0.5 allow unauthenticated attackers to log in to the web interface or telnet service as the 'user' user.

Victure PC420 1.1.39 was discovered to use a weak encryption key for the file enabled_telnet.dat on the Micro SD card.

Victure PC420 1.1.39 was discovered to contain a hardcoded root password which is stored in plaintext.

An exploitable vulnerability exists in the Wi-Fi Access Point feature of the Roav A1 Dashcam running version RoavA1SWV1.9. A set of default credentials can potentially be used to connect to the device. An attacker can connect to the AP to trigger this vulnerability.
