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 · unedited
Multiple TP-LINK products allow a network-adjacent attacker with an administrative privilege to execute arbitrary OS commands by restoring a crafted backup file. The affected device, with the initial configuration, allows login only from the LAN port or Wi-Fi.

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 confidence

Multiple TP-LINK devices contain a command injection vulnerability in the backup restore function. An attacker with admin credentials can craft a malicious backup file that, when restored to the device, executes arbitrary OS commands due to improper input sanitization of the backup file contents.

MitigationApply vendor-supplied firmware updates when available. Until then, restrict administrative access to trusted LAN segments only and avoid restoring backup files from untrusted sources.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm device is TP-LINK
    Access the device admin interface or check the device label/menu to verify the manufacturer is TP-LINK. Run 'arp -a' or check DHCP lease tables to identify the device vendor by MAC address prefix (TP-LINK MAC prefixes include 14-CC-20, 50-C7-BF, 1C-3B-F3, etc.).
    Affected if The target device is not a TP-LINK device, then this CVE does not apply.
  2. Identify firmware version
    Log into the TP-LINK device admin interface (typically via web browser at 192.168.0.1 or 192.168.1.1). Navigate to System > Firmware Upgrade or Status page to view the current firmware version. Alternatively, check the device documentation or label for firmware information.
    Affected if The installed firmware version falls within any known affected version range for this CVE. If the version is unknown or cannot be determined, the device may still be affected.
  3. Verify administrative access exists
    Confirm valid admin credentials exist for the device. Attempt to log into the admin web interface with admin-level privileges. Check if default credentials are still in use or if custom admin accounts are configured.
    Affected if Administrative credentials are required for the backup restore function; without admin access, this specific attack path cannot be exploited.
  4. Confirm backup restore feature is accessible
    In the device admin interface, look for Settings > Backup & Restore, System Tools > Backup Configuration, or similar menu options. Verify the Restore button or function is present and accessible to the admin user.
    Affected if The backup restore functionality exists and is accessible to admin users, creating the attack surface for command injection.

A TP-LINK device is affected if it is a TP-LINK device with a vulnerable firmware version that has an accessible backup restore feature and administrative credentials can be obtained by an attacker.
