CVE-2022-43028
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 · uneditedTenda TX3 US_TX3V1.0br_V16.03.13.11_multi_TDE01 was discovered to contain a stack overflow via the timeZone parameter at /goform/SetSysTimeCfg.
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 confidenceTenda TX3 router firmware US_TX3V1.0br_V16.03.13.11 contains a stack overflow vulnerability in the SetSysTimeCfg form handler. The timeZone parameter passed to /goform/SetSysTimeCfg is not properly bounds-checked before being copied to a stack-allocated buffer, allowing an attacker to overflow the stack with arbitrary data.

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 Tenda TX3 router on the networkCheck router model through device discovery, web interface login page, or DHCP fingerprints. Look for 'Tenda TX3' or 'TX3' in device identification.Affected if The device is not a Tenda TX3 router, then this CVE does not apply.
-
Check installed firmware versionLog into the router web interface and navigate to System Settings > Firmware Upgrade, or check the admin page for version information. Alternatively, inspect the firmware file if downloaded locally.Affected if Firmware version is exactly 16.03.13.11, indicating the affected version.
-
Verify web management interface is accessibleAttempt to access the router's web interface on the default IP (usually 192.168.0.1 or 192.168.1.1) via HTTP. Confirm the /goform/SetSysTimeCfg endpoint responds to POST requests.Affected if The web interface and SetSysTimeCfg endpoint are reachable from the attacker's network position.
-
Check if remote administration is enabledIn the router web interface, navigate to Advanced > Remote Management, or System Settings > Remote Access. Verify whether remote management via WAN is enabled.Affected if Remote administration is enabled, allowing unauthenticated attackers on the internet to reach the vulnerable endpoint.
-
Confirm timeZone parameter processing existsSend a benign POST request to /goform/SetSysTimeCfg with a normal timeZone value and verify the router accepts and processes it. This confirms the vulnerable code path is present.Affected if The endpoint processes the timeZone parameter without immediate error, indicating the vulnerable handler is active.
The environment is affected if it is a Tenda TX3 router running firmware version 16.03.13.11 with the web management interface (especially the SetSysTimeCfg endpoint) accessible from an attacker's location, regardless of whether remote administration appears enabled in settings.

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; in the interim, restrict access to the router's web management interface to trusted networks only and disable remote administration if enabled.
