CVE-2023-30351
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedShenzen Tenda Technology IP Camera CP3 V11.10.00.2211041355 was discovered to contain a hard-coded default password for root which is stored using weak encryption. This vulnerability allows attackers to connect to the TELNET service (or UART) by using the exposed credentials.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Tenda CP3 IP Camera firmware V11.10.00.2211041355 contains a hard-coded default password for the root account that is stored using weak encryption. Attackers with network access to the device can obtain these credentials and authenticate to the exposed TELNET service (or via hardware UART) with full root privileges, enabling complete device compromise.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelCheck the device label, web interface, or system information to confirm the device is a Tenda CP3 IP CameraAffected if The device is not a Tenda CP3 camera, this CVE does not apply
-
Check the firmware versionAccess the camera's web interface (usually via HTTP on the device IP) and navigate to System or Device Info settings to view the firmware version, or use the manufacturer's discovery toolAffected if Firmware version is NOT exactly 11.10.00.2211041355, the specific affected version
-
Verify if TELNET service is accessibleAttempt to connect to port 23 on the camera IP address using a TELNET client (e.g., telnet <camera_ip>) or run a port scan targeting port 23Affected if TELNET port 23 is open and responding, exposing the service that can be attacked using the hardcoded credentials
-
Inspect for hardcoded credentialsIf you have access to the firmware (via firmware extraction or backup), search for the root password hash or default credential strings in configuration files or the /etc/shadow equivalentAffected if Default root credentials are found hardcoded in the firmware filesystem
The device is affected if it is a Tenda CP3 camera running firmware version 11.10.00.2211041355 AND has TELNET service port 23 accessible on the network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate camera firmware to a patched version that removes the hard-coded credentials; if unavailable, disable TELNET service, change default credentials immediately, and restrict network access to the camera.
