CVE-2023-47802
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 regarding improper neutralization of special elements used in an OS command ('OS Command Injection') is found in the IP block functionality. This allows remote authenticated users with administrator privileges to execute arbitrary commands via unspecified vectors. The following models with Synology Camera Firmware versions before 1.0.7-0298 may be affected: BC500 and TC500.
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 IP block functionality in Synology BC500 and TC500 camera firmware lacks proper input sanitization, allowing an authenticated administrator to inject arbitrary OS commands through unspecified vectors. This command injection occurs due to improper neutralization of special elements in user-supplied input processed by the IP block feature.

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 camera modelAccess the device web interface or check the physical device label to confirm the model is Synology BC500 or TC500Affected if The device is a Synology BC500 or TC500 camera
-
Check the installed firmware versionLog into the camera admin panel and navigate to System > Firmware/About, or use SSH to run 'cat /etc/version' or check the web interface version displayAffected if The firmware version is lower than 1.0.7-0298 (for example, 1.0.6-xxxx or earlier)
-
Verify the IP Block feature is accessibleLog in as administrator and navigate to Network Security or Access Control settings in the web interface to confirm the IP Block functionality exists and is configurableAffected if The IP Block feature is present and the administrator account has access to configure it
A user is affected if they have a Synology BC500 or TC500 camera running firmware version lower than 1.0.7-0298 with the IP Block feature accessible to an authenticated administrator.
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.
dbcve · scoped1.0.7-0298
Update Synology BC500 and TC500 camera firmware to version 1.0.7-0298 or later to patch the vulnerability. As a compensating control, limit administrative access to trusted personnel only and monitor for suspicious command execution.
Firmware 1.0.7-0298 or later for BC500 and TC500
- Download the Synology BC500 or TC500 firmware version 1.0.7-0298 or later from the official Synology website
- Log into the camera's web management interface as administrator
- Navigate to the System or Maintenance section of the camera settings
- Locate the Firmware Update or Software Update option
- Upload and apply the new firmware version
- Verify the firmware update was successful and the camera is functioning normally
