CVE-2026-39462
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 · uneditedA vulnerability exists in SenseLive X3050’s web management interface in which password updates are not reliably applied due to improper handling of credential changes on the backend. After the device undergoes a factory restore using the SenseLive Config 2.0 tool, the interface may indicate that the password update was successful; however, the system may continue to accept the previous or default credentials, demonstrating that the password-change process is not consistently enforced. Even after a factory reset, attempted password changes may fail to propagate correctly.
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 SenseLive X3050 web management interface has a credential management flaw where password updates are not reliably propagated to the backend authentication system. Despite the UI reporting successful password changes, the device continues accepting previous or default credentials, allowing authentication bypass. This persists even after factory resets.

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 model and firmware versionAccess the SenseLive web management interface and navigate to System > Status or About page to view the firmware version. Alternatively, check the device label or documentation for the exact model number and firmware version.Affected if The device is a Senselive X3500 running firmware version 1.523
-
Verify default credentials are still acceptedAttempt to log in to the web interface using the default credentials (typically admin/admin or admin/password, consult device documentation for default credentials).Affected if Default credentials still grant access after a password change was performed through the UI
-
Test password change propagationLog in to the web interface, navigate to the password change or account settings section, change the password to a new value, log out, and attempt to log in with the new password.Affected if The new password is rejected while the previous password still grants access
-
Perform factory reset and test default credentialsExecute a factory reset through the device interface or physical reset button, then attempt to log in with documented default credentials.Affected if Default credentials still work after a factory reset has been performed
-
Check authentication logs for credential anomaliesReview the device authentication logs or system logs for entries showing successful logins with both old and new passwords, or multiple authentication attempts.Affected if Logs show successful authentication using both changed and previous passwords simultaneously
A user is affected if they have a Senselive X3500 on firmware 1.523 and the device accepts both the old password and any newly set password, or default credentials remain valid after password changes or factory resets.

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 dataIsolate the device on a restricted network segment, disable unauthenticated remote access to the web interface, and monitor for authentication attempts using default credentials until a vendor firmware patch is available.
