CVE-2024-13870
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 · uneditedAn improper access control vulnerability exists in Bitdefender Box 1 (firmware version 1.3.52.928 and below) that allows an unauthenticated attacker to downgrade the device's firmware to an older, potentially vulnerable version of a Bitdefender-signed firmware. The attack requires Bitdefender BOX to be booted in Recovery Mode and that the attacker be present within the WiFi range of the BOX unit.
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 confidenceAn improper access control vulnerability in Bitdefender Box 1 firmware (versions 1.3.52.928 and below) allows an unauthenticated attacker within WiFi range to downgrade the device to an older, vulnerable firmware version by exploiting the recovery mode boot process. The recovery mode lacks proper authentication checks, enabling firmware downgrade attacks even though the firmware is Bitdefender-signed.

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 device modelLocate the physical Bitdefender Box device or check your network devices for 'Bitdefender Box' or 'BDV Box' model identifierAffected if Device is not a Bitdefender Box 1 (this CVE applies only to that specific model)
-
Check installed firmware versionAccess the Bitdefender Box admin interface (typically via local IP or mybitdefender.com portal) and navigate to Settings > Device Info > Firmware Version, or log into the device CLI and run 'version' or 'fw_info' commandAffected if Firmware version displayed is 1.3.52.928 or lower (the device is running a vulnerable version)
-
Verify recovery mode accessibilityPower cycle the device and observe the boot process for recovery mode accessibility indicators, or check if recovery mode can be triggered without authentication credentialsAffected if Recovery mode boots without requiring authentication or authorization checks
-
Assess WiFi network exposureCheck whether the Bitdefender Box WiFi interface is enabled and visible to nearby unauthenticated devices within wireless rangeAffected if WiFi is enabled and the device is within range of untrusted wireless clients
You are affected if you have a Bitdefender Box 1 running firmware version 1.3.52.928 or below, with recovery mode accessible without authentication and WiFi interface exposed to potential attackers in range.

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 dataImplement strong authentication requirements in recovery mode and add firmware version validation to prevent downgrading to older vulnerable versions. Apply available firmware updates that address this access control weakness.
