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
A vulnerability was found in TOTOLINK A3002R and A3002RU 3.0.0-B20230809.1615. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file /boafrm/formMapDelDevice of the component HTTP POST Request Handler. The manipulation of the argument macstr leads to command injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.

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

TOTOLINK A3002R and A3002RU routers running firmware version 3.0.0-B20230809.1615 contain a command injection vulnerability in the /boafrm/formMapDelDevice HTTP POST handler. The macstr parameter is not properly sanitized before being passed to a system call, allowing remote attackers to execute arbitrary commands via crafted POST requests.

MitigationApply vendor firmware updates if available; otherwise isolate affected devices behind a firewall or replace with supported hardware, as these models may be end-of-life.

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. Identify the router model
    Check the device label or log into the web management interface and look for the model name in the status or system information page
    Affected if The device is not a TOTOLINK A3002R or A3002RU router, then it is not affected by this specific CVE
  2. Check the firmware version
    Log into the router web interface and navigate to the System or Firmware section to view the installed firmware version, or check the upgrade page
    Affected if The firmware version is NOT exactly 3.0.0-B20230809.1615, then the device is not affected by this specific CVE (only this exact version is listed as affected)
  3. Verify the web management interface is accessible
    Attempt to access the router login page via HTTP (typically at the default gateway IP address) using a web browser
    Affected if The web interface is not accessible or the /boafrm/formMapDelDevice handler does not exist, the command injection cannot be triggered even on the affected firmware version

The device is affected only if it is a TOTOLINK A3002R or A3002RU router running firmware version 3.0.0-B20230809.1615 AND the web management interface is accessible to the attacker.
