A hard-coded password vulnerability exists in the Libcli Test Environment functionality of D-LINK DIR-3040 1.13B03. A specially crafted network request can lead to code execution. An attacker can send a sequence of requests to trigger this vulnerability.

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.

D-Link D-View InstallApplication Use of Hard-coded Credentials Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass authentication on affected installations of D-Link D-View. Authentication is not required to exploit this vulnerability. The specific flaw exists within the InstallApplication class. The class contains a hard-coded password for the remotely reachable database. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-19553.

The D-link router DIR-885L-MFC 1.15b02, v1.21b05 is vulnerable to credentials disclosure in telnet service through decompilation of firmware, that allows an unauthenticated attacker to gain access to the firmware and to extract sensitive data.

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.

D-Link DGS-1500 Ax devices before 2.51B021 have a hardcoded password, which allows remote attackers to obtain shell access.

D-Link DVG-3104MS version 1.0.2.0.3, 1.0.2.0.4, and 1.0.2.0.4E contains hard-coded credentials for undocumented user accounts in the '/etc/passwd' file. As weak passwords have been used, the plaintext passwords can be recovered from the hash values. NOTE: This vulnerability only affects products that are no longer supported by the maintainer

Certain models of D-Link wireless routers do not properly validate user input in the telnet service, allowing unauthenticated remote attackers to use hard-coded credentials to log into telnet and inject arbitrary OS commands, which can then be executed on the device.

An information disclosure vulnerability exists in the WiFi Smart Mesh functionality of D-LINK DIR-3040 1.13B03. A specially-crafted network request can lead to command execution. An attacker can connect to the MQTT service to trigger this vulnerability.

Quagga Services on D-Link DIR-2640 less than or equal to version 1.11B02 use default hard-coded credentials, which can allow a remote attacker to gain administrative access to the zebra or ripd those services. Both are running with root privileges on the router (i.e., as the "admin" user, UID 0).

An issue was discovered on D-Link DSL-2640B B2 EU_4.01B devices. A hard-coded account allows management-interface login with high privileges. The logged-in user can perform critical tasks and take full control of the device.

Improper Input Validation in Hitron Systems DVR LGUVR-16H 1.02~4.02 allows an attacker to cause network attack in case of using defalut admin ID/PW.

Improper Input Validation in Hitron Systems DVR LGUVR-4H 1.02~4.02 allows an attacker to cause network attack in case of using defalut admin ID/PW.

Improper Input Validation in Hitron Systems DVR LGUVR-8H 1.02~4.02 allows an attacker to cause network attack in case of using defalut admin ID/PW.

Improper Input Validation in Hitron Systems DVR HVR-8781 1.03~4.02 allows an attacker to cause network attack in case of using defalut admin ID/PW.

Improper Input Validation in Hitron Systems DVR HVR-16781 1.03~4.02 allows an attacker to cause network attack in case of using defalut admin ID/PW.

A vulnerability in the default configuration of the Cisco Aironet Active Sensor could allow an unauthenticated, remote attacker to restart the sensor. The vulnerability is due to a default local account with a static password. The account has privileges only to reboot the device. An attacker could exploit this vulnerability by guessing the account name and password to access the CLI. A successful exploit could allow the attacker to reboot the device repeatedly, creating a denial of service (DoS) condition. It is not possible to change the configuration or view sensitive data with this account. Versions prior to DNAC1.2.8 are affected.

Improper Input Validation in Hitron Systems DVR HVR-4781 1.03~4.02 allows an attacker to cause network attack in case of using defalut admin ID/PW.

Airleader Master and Easy <= 6.21 devices have default credentials that can be used for a denial of service.

An issue was discovered on the Audi Universal Traffic Recorder 2.88. It has Susceptibility to denial of service. It uses the same default credentials for all devices and does not implement proper multi-device authentication, allowing attackers to deny the owner access by occupying the only available connection. The SSID remains broadcast at all times, increasing exposure to potential attacks.

Adobe ColdFusion versions Update 14 (and earlier) and Update 4 (and earlier) are affected by a Use of Hard-coded Credentials vulnerability that could result in application denial-of-service by gaining access to start/stop arbitrary services. Exploitation of this issue does not require user interaction.

Fujitsu Real-time Video Transmission Gear "IP series" use hard-coded credentials, which may allow a remote unauthenticated attacker to initialize or reboot the products, and as a result, terminate the video transmission. Affected products and versions are as follows: IP-HE950E firmware versions V01L001 to V01L053, IP-HE950D firmware versions V01L001 to V01L053, IP-HE900E firmware versions V01L001 to V01L010, IP-HE900D firmware versions V01L001 to V01L004, IP-900E / IP-920E firmware versions V01L001 to V02L061, IP-900D / IP-900ⅡD / IP-920D firmware versions V01L001 to V02L061, IP-90 firmware versions V01L001 to V01L013, and IP-9610 firmware versions V01L001 to V02L007.
