CVE-2023-44017
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 AC10U v1.0 US_AC10UV1.0RTL_V15.03.06.49_multi_TDE01 was discovered to contain a stack overflow via the timeZone parameter in the fromSetSysTime function.
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 stack buffer overflow vulnerability exists in the fromSetSysTime function of Tenda AC10U v1.0 router firmware (version US_AC10UV1.0RTL_V15.03.06.49_multi_TDE01). The vulnerability is triggered via the timeZone parameter in HTTP requests to the web management interface, allowing remote attackers to potentially overwrite stack memory and execute arbitrary code.

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 router firmware versionAccess the router's web management interface and navigate to System Settings > System Info, or check the firmware version via the admin panel. Alternatively, use Nmap or curl to access the router's HTTP service and examine version disclosure pages.Affected if Firmware version is exactly US_AC10UV1.0RTL_V15.03.06.49_multi_TDE01 (15.03.06.49_multi_tde01)
-
Confirm fromSetSysTime function is presentIf you have access to the firmware binary, extract and analyze it using binwalk or strings to locate the fromSetSysTime function referenced in the vulnerability.Affected if The fromSetSysTime function exists in the firmware image, indicating the vulnerable code path is present
-
Verify web management interface is accessibleAttempt to access the router's HTTP interface on ports 80 or 443 from an authorized network segment. Check if the login page loads at the router's LAN IP address.Affected if The web management interface responds to HTTP requests, making the timeZone parameter injectable
-
Check for unauthenticated or authenticated time zone settingSend an HTTP POST request to the endpoint handling timeZone parameter (commonly /goform/ or similar). Inspect the router's form submission URLs in the web interface for time-related settings.Affected if A timeZone parameter can be submitted via HTTP POST to the fromSetSysTime handler without immediate validation
You are affected if the Tenda AC10U runs firmware version 15.03.06.49_multi_tde01 and the web management interface is accessible, allowing injection through the timeZone parameter to the fromSetSysTime function.

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 dataRestrict network access to the router's web management interface immediately. Contact Tenda for a patched firmware version; if unavailable, consider network segmentation or replacement of the device.
