NVD · uneditedIn Tenda AC15 V15.03.05.19, the function GetValue contains a stack-based buffer overflow vulnerability.
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-based buffer overflow vulnerability exists in the GetValue function of Tenda AC15 wireless router firmware version V15.03.05.19. With a CVSS score of 9.8, this critical flaw is likely exploitable remotely without authentication and could allow an attacker to execute arbitrary code by overflowing a stack-allocated buffer in the affected function.

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 device modelAccess the router's web管理界面 (typically at 192.168.0.1) or check the device label to confirm it is a Tenda AC15 router.Affected if The device is not a Tenda AC15 model.
-
Check the firmware versionLog into the router web interface and navigate to System Settings > Firmware Upgrade or similar, or use the command 'cat /proc/version' if you have telnet/ssh access to the device.Affected if The firmware version is exactly 15.03.05.19.
-
Verify the web interface is accessibleAttempt to reach the router's HTTP/HTTPS management page from the network. The GetValue function vulnerability is triggered via the web server.Affected if The web management interface is accessible on the network.
-
Check if UPnP or remote management is enabledIn the router web interface, check Settings > Advanced > UPnP or Remote Management settings. The vulnerability may be exploitable remotely if these services expose the web server externally.Affected if UPnP or remote management is enabled and the router WAN interface is accessible.
You are affected if you have a Tenda AC15 router running firmware version 15.03.05.19 with its web interface accessible on the network.

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 the latest firmware patch from Tenda for the AC15 router. If no patched firmware is available, restrict network access to the device's management interface and consider network segmentation or device replacement.
