Denver SHO-110 IP Camera Unauthenticated Snapshot Access

Denver SHO-110 IP cameras expose a secondary HTTP service on TCP port 8001 that provides access to a '/snapshot' endpoint without authentication. While the primary web interface on port 80 enforces authentication, the backdoor service allows any remote attacker to retrieve image snapshots by directly requesting the 'snapshot' endpoint. An attacker can repeatedly collect snapshots and reconstruct the camera stream, compromising the confidentiality of the monitored environment.

Undocumented access path in mH-DEVELOPER

mH-DEVELOPER smart home module contains a hardcoded SSH public key in /root/.ssh/authorized_keys, serving as a potential backdoor. The SSH daemon allows root login via key authentication and starts automatically. An attacker with the matching private key can gain a root shell on any affected device, resulting in full system compromise. The key cannot be removed without remounting the file system and survives a factory reset. Vendor notes that this functionality was used only for service purposes. This issue was fixed in version 3.0.30

Unintended Telnet Activation via Magic Packet on End‑of‑Life NETGEAR Devices

Some end of service NETGEAR products provide "TelnetEnable" functionality, which allows a magic packet to activate telnet service on the box.

Festo: MSE6-C2M/D2M/E2M Incomplete User Documentation of Remote Accessible Functions

In products of the MSE6 product-family by Festo a remote authenticated, low privileged attacker could use functions of undocumented test mode which could lead to a complete loss of confidentiality, integrity and availability.

CWE-1242: Inclusion of Undocumented Features

DBLTek GoIP Telnet Admin Interface Undocumented Backdoor

DBLTek GoIP devices (models GoIP 1, 4, 8, 16, and 32) contain an undocumented vendor backdoor in the Telnet administrative interface that allows remote authentication as an undocumented user via a proprietary challenge–response scheme which is fundamentally flawed. Because the challenge response can be computed from the challenge itself, a remote attacker can authenticate without knowledge of a secret and obtain a root shell on the device. This can lead to persistent remote code execution, full device compromise, and arbitrary control of the device and any managed services. The firmware used within these devices was updated in December 2016 to make this vulnerability more complex to exploit. However, it is unknown if DBLTek has taken steps to fully mitigate.

Inclusion of Undocumented Features

Inclusion of undocumented features vulnerability accessible when logged on with a privileged access level on the following Schweitzer Engineering Laboratories relays could allow the relay to behave unpredictably: SEL-700BT Motor Bus Transfer Relay, SEL-700G Generator Protection Relay, SEL-710-5 Motor Protection Relay, SEL-751 Feeder Protection Relay, SEL-787-2/-3/-4 Transformer Protection Relay, SEL-787Z High-Impedance Differential Relay . See product instruction manual appendix A dated 20240308 for more details regarding the SEL-751 Feeder Protection Relay. For more information for the other affected products, see their instruction manuals dated 20240329.

Inclusion of undocumented features issue exists in UD-LT2 firmware Ver.1.00.008_SE and earlier. A remote attacker may disable the LAN-side firewall function of the affected products, and open specific ports.

Inclusion of undocumented features or chicken bits issue exists in UD-LT1 firmware Ver.2.1.8 and earlier and UD-LT1/EX firmware Ver.2.1.8 and earlier. A remote attacker may disable the firewall function of the affected products. As a result, an arbitrary OS command may be executed and/or configuration settings of the device may be altered.

Inclusion of undocumented features or chicken bits issue exists in AE1021 firmware versions 2.0.10 and earlier and AE1021PE firmware versions 2.0.10 and earlier, which may allow a logged-in user to enable telnet service.

Undocumented Administrative Accounts

Undocumented administrative accounts were getting created to facilitate access for applications running on board.This issue affects BLU-IC2: through 1.19.5; BLU-IC4: through 1.19.5.

Enabling SSH and Shellinabox on the vulnerable machine

E3 Site Supervisor Control (firmware version < 2.31F01) contains a hidden API call in the application services that enables SSH and Shellinabox, which exist but are disabled by default. An attacker with admin access to the application services can utilize this API to enable remote access to the underlying OS.
