CVE-2021-47731
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 · uneditedSelea Targa IP OCR-ANPR Camera contains a hard-coded developer password vulnerability that allows unauthorized configuration access through an undocumented page. Attackers can exploit the hidden endpoint by using the hard-coded password 'Selea781830' to enable configuration upload and overwrite device settings.
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 Selea Targa IP OCR-ANPR camera ships with a hard-coded developer password ('Selea781830') embedded in the firmware. An undocumented administrative page accepts this password to bypass authentication, allowing attackers to enable configuration uploads and overwrite device settings including network parameters, user credentials, and ANPR settings.

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 Selea device modelAccess the camera's web interface or check the device firmware/version information through the management interface to confirm the exact model (Izero Box, Izero Column Entry/8, Izero Column Full/8, Targa 504, Targa 512, Targa 704 Ilb, Targa 704 Tkm, or Targa 710 Inox)Affected if The device is any of the listed Selea models (Izero Box, Izero Column, or Targa series) and is accessible on the network
-
Locate the undocumented configuration pageAttempt to access the hidden configuration page by navigating to typical undocumented paths or observing network traffic from the device to identify unusual endpoints. The exact path is not specified in the CVE but is described as an undocumented configuration pageAffected if The undocumented configuration page is reachable and accepts authentication
-
Test the hard-coded credentialAttempt to authenticate to the undocumented configuration page using the hard-coded password 'Selea781830' as the credentialAffected if Authentication succeeds with password 'Selea781830', confirming the hard-coded credential vulnerability is present
-
Verify network exposure of management interfaceCheck whether the camera management interface (HTTP/HTTPS ports) is directly accessible from untrusted networks rather than being isolated behind a firewall or VPNAffected if The camera management interface is accessible from untrusted network segments, allowing potential attackers to reach the undocumented page and exploit the hard-coded credential
A user is affected if they operate any Selea Izero or Targa camera model whose management interface is exposed to network access where attackers could reach the undocumented configuration page and authenticate using the hard-coded password 'Selea781830'.
Generated from the published advisory. Verify against your own configuration.
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 dataImmediately restrict network access to camera management interfaces via firewall rules or VLAN segmentation. If available, apply vendor firmware updates that remove the hard-coded credentials. Otherwise, consider replacing affected devices or implementing additional authentication layers such as VPN access to management interfaces.
