CVE-2023-51741
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 · uneditedThis vulnerability exist in Skyworth Router CM5100, version 4.1.1.24, due to transmission of authentication credentials in plaintext over the network. A remote attacker could exploit this vulnerability by eavesdropping on the victim’s network traffic to extract username and password from the web interface (Password Reset Page) of the vulnerable targeted system.
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 Skyworth Router CM5100 version 4.1.1.24 transmits user credentials in plaintext during the password reset process. An attacker on the same network can intercept the HTTP traffic to capture username and password values sent to the web interface.

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 firmware versionAccess the router web interface and navigate to the Status or System Information page to view the firmware version, or check via CLI if availableAffected if The firmware version displayed is 4.1.1.24
-
Determine if HTTP is enabled for the web interfaceAttempt to access the router login page using http:// (not https://) to see if an HTTP connection is acceptedAffected if The web interface responds over HTTP (port 80) rather than redirecting to HTTPS
-
Verify if HTTPS is enforced for management trafficCheck the router's web management settings under Security or Network settings to see if HTTPS-only mode is enabledAffected if HTTPS is not enabled or enforced for the web management interface
-
Confirm plaintext HTTP traffic capture is possibleUse a packet capture tool on the same network segment while initiating a password reset operation to observe if credentials are transmitted in cleartext over HTTPAffected if Network capture shows username and password sent in plaintext over HTTP during password reset
The environment is affected if the device runs firmware version 4.1.1.24 and the web management interface is accessible over HTTP without TLS encryption.

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 dataEnable HTTPS/TLS for all web management traffic or implement network segmentation/VPN access to prevent unauthorized traffic interception. Monitor for vendor firmware updates that address this credential exposure.
