CVE-2025-9523
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 detected in Tenda AC1206 15.03.06.23. Affected is the function GetParentControlInfo of the file /goform/GetParentControlInfo. The manipulation of the argument mac results in stack-based buffer overflow. It is possible to launch the attack remotely. The exploit is now 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 confidenceStack-based buffer overflow in Tenda AC1206 router firmware 15.03.06.23 allows remote attackers to overflow a stack buffer via the 'mac' parameter in the /goform/GetParentControlInfo function. The vulnerability is exploitable remotely without authentication and a public exploit exists.

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 Tenda AC1206 router modelLog into the router web interface (typically at 192.168.0.1) and check the device information page, or check the device label/marketing materials for the model number AC1206.Affected if The device is not a Tenda AC1206 router.
-
Identify installed firmware versionIn the router web interface, navigate to System Settings > Firmware Upgrade or Administration > System Management to view the current firmware version. Alternatively, check via telnet/SSH if enabled, or inspect the firmware file if you have access to it.Affected if The firmware version is 15.03.06.23.
-
Verify web interface is accessibleAttempt to reach the router's web interface from the network where the router is deployed. Try accessing the IP address (commonly 192.168.0.1) via HTTP in a web browser.Affected if The /goform/GetParentControlInfo endpoint responds to requests.
-
Check if remote WAN access is enabledIn the router web interface, examine the WAN settings or Remote Management settings (often under Advanced > Remote Management or System Tools > Admin Settings). Verify if remote access from WAN (internet) to the web interface is enabled.Affected if Remote WAN access to the router's web interface is enabled and the device is directly exposed to the internet.
A user is affected if they have a Tenda AC1206 router running firmware version 15.03.06.23 with the web interface accessible remotely, as the vulnerability lies in the /goform/GetParentControlInfo function via the mac parameter.

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 dataApply vendor firmware patch when available; if no patch exists, restrict remote access to the router's web interface via firewall or disable WAN access to prevent exploitation.
