CVE-2025-12618
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 has been found in Tenda AC8 16.03.34.06. This impacts an unknown function of the file /goform/DatabaseIniSet. The manipulation of the argument Time leads to buffer overflow. The attack can be initiated 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 · moderate confidenceA buffer overflow vulnerability exists in Tenda AC8 router firmware version 16.03.34.06. The /goform/DatabaseIniSet endpoint does not properly validate the 'Time' argument, allowing an attacker to overflow a buffer. This remote, likely unauthenticated attack achieves critical severity (CVSS 9.8) and could enable remote code execution.

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 the router modelLog into the router web interface or check the device label to confirm it is a Tenda AC8 modelAffected if The device is not a Tenda AC8 router, this CVE does not apply
-
Check the firmware versionNavigate to the router admin panel (typically at 192.168.0.1), go to System Settings or Administration section, and locate the firmware version information. Alternatively, check via CLI if telnet/ssh is enabledAffected if The firmware version is exactly 16.03.34.06 - only this specific version is affected
-
Determine if the web management interface is exposedCheck router settings under Advanced or Security settings to see if remote web management is enabled (often labeled as 'Remote Management' or 'Web Management Remote'). Also verify network exposure by checking WAN IP accessibility on port 80/8080Affected if Remote management is enabled and the router is accessible from the WAN side, the vulnerable endpoint can be reached externally
-
Verify the DatabaseIniSet endpoint existsAttempt to access http://[router-ip]/goform/DatabaseIniSet via HTTP request (note: this is for detection purposes to confirm the endpoint exists on the device)Affected if The endpoint responds (even with an error), it indicates the vulnerable function is present on the device
The device is affected only if it is a Tenda AC8 router running firmware version 16.03.34.06 with the web management interface accessible (locally or remotely).

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 if available; otherwise restrict management interface to trusted networks or disable remote administration, and monitor for indicators of compromise.
