CVE-2023-28704
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 · uneditedFurbo dog camera has insufficient filtering for special parameter of device log management function. An unauthenticated remote attacker in the Bluetooth network with normal user privileges can exploit this vulnerability to perform command injection attack to execute arbitrary system commands or disrupt service.
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 Furbo dog camera contains a command injection vulnerability in its device log management function. The function fails to properly filter/sanitize special parameters, allowing an unauthenticated attacker with Bluetooth network access and normal user privileges to inject and execute arbitrary system commands or cause service disruption.

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 Furbo device firmware versionAccess the Furbo device settings or administrative interface to retrieve the currently installed firmware version numberAffected if The installed firmware version is 542 (exact match to affected version)
-
Determine if Bluetooth is enabledCheck the device network configuration or settings to see if Bluetooth connectivity is active on the Furbo deviceAffected if Bluetooth is enabled and discoverable, allowing unauthenticated proximity access
-
Verify log management function accessibilityInspect the device web API or companion application for the log management endpoint and confirm it accepts user-supplied parametersAffected if The log management function is accessible to users with normal privileges without additional authentication
-
Check for injected commands in system logsReview system or application logs on the Furbo device for unexpected command patterns, special characters (such as ; | ` $()), or suspicious command structuresAffected if Log entries contain unexpected command syntax or malformed entries suggesting injection attempts
-
Confirm normal user account configurationReview the list of user accounts and their privilege levels configured on the Furbo device or companion applicationAffected if Normal (non-administrator) user accounts exist and can access the log management feature
A Furbo Dog Camera running firmware version 542 with Bluetooth enabled and accessible to normal users is affected if the log management function accepts unsanitized input.

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 the Furbo device firmware to a version that implements proper input validation and sanitization on the log management function parameters. Until a patch is available, restrict Bluetooth proximity access to trusted users only.
