CVE-2025-8244
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 was found in TOTOLINK X15 1.0.0-B20230714.1105. It has been classified as critical. Affected is an unknown function of the file /boafrm/formMapDelDevice of the component HTTP POST Request Handler. The manipulation of the argument macstr leads to buffer overflow. It is possible to launch the attack 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 confidenceBuffer overflow vulnerability in TOTOLINK X15 router firmware (v1.0.0-B20230714.1105) in the HTTP POST handler for /boafrm/formMapDelDevice. The macstr parameter is not properly bounds-checked before use, allowing an attacker to overwrite adjacent memory by sending an oversized value. This is a remote, network-based attack requiring no authentication (CVSS 9.8).

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.
-
Confirm device modelExamine the router device label or log into the web interface to verify the model is TOTOLINK X15Affected if Device is not a TOTOLINK X15 router (not affected)
-
Check installed firmware versionAccess the router web interface (typically 192.168.0.1 or 192.168.1.1), navigate to Status or System Settings, and record the firmware version stringAffected if Firmware version is exactly 1.0.0-B20230714.1105 (exact match is vulnerable)
-
Verify HTTP service is network-accessibleAttempt to reach the router web interface IP address on port 80 or 443 from a remote hostAffected if Router HTTP service is reachable from attacker-controlled network location
-
Confirm remote management is enabledIn router web interface, locate the Remote Management or Remote Access setting (usually under Security or Advanced settings) and check if it allows HTTP access from WANAffected if Remote management is enabled, exposing the /boafrm/formMapDelDevice endpoint to external attackers
The device is affected only if it is a TOTOLINK X15 running firmware version 1.0.0-B20230714.1105 AND the router HTTP management interface is accessible from the network where an attacker could send the malicious POST request.

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 router firmware if vendor releases a patch; otherwise, disable remote management interfaces, block the affected HTTP endpoints at the network perimeter, or replace the device if end-of-life.
