CVE-2023-44019
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 mac parameter in the GetParentControlInfo 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 · high confidenceTenda AC10U v1.0 router firmware US_AC10UV1.0RTL_V15.03.06.49 contains a stack-based buffer overflow in the GetParentControlInfo function. The mac parameter from HTTP requests is not properly validated before being copied into a fixed-size stack buffer, allowing remote attackers to overwrite stack memory and potentially execute arbitrary code with root privileges on the device.

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 firmware versionAccess the router web interface (typically at 192.168.0.1) and navigate to System Settings > Firmware Upgrade, or check the label on the device itself. The affected version is US_AC10UV1.0RTL_V15.03.06.49_multi_tde01.Affected if The installed firmware version matches exactly 15.03.06.49_multi_tde01
-
Verify parent control feature statusLog into the router web interface and check the Parent Control settings page. Look for whether parental controls are currently enabled or configured.Affected if Parent control feature is enabled or has been configured with any mac address entries
-
Confirm web interface accessibilityDetermine if the router HTTP service is exposed to untrusted networks by checking your network configuration or firewall rules. The vulnerability is exploitable via HTTP requests to the device.Affected if The router web interface is accessible from outside your trusted local network
-
Inspect HTTP request handling for mac parameterIf you have access to the device internally, examine network traffic or logs for requests to the GetParentControlInfo function. The vulnerability occurs when the mac parameter from HTTP requests is copied to a stack buffer without validation.Affected if HTTP requests containing a mac parameter can be sent to the device's parent control functionality
Your device is affected if it runs firmware version 15.03.06.49_multi_tde01 AND has the parent control feature enabled, making it exploitable via crafted HTTP requests with an oversized mac parameter.
Generated from the published advisory. Verify against your own configuration.
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, disable the parent control feature via the web interface, place the device in an isolated network segment, and consider replacing the end-of-life device with a currently supported model.
