CVE-2022-41482
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 AC1200 US_AC6V2.0RTL_V15.03.06.51_multi_TDE01 was discovered to contain a buffer overflow in the 0x47c5dc function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.
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 the Tenda AC1200 router firmware (US_AC6V2.0RTL_V15.03.06.51) in function 0x47c5dc. The vulnerability allows remote attackers to send a crafted HTTP request that triggers the buffer overflow, resulting in denial of service. The high CVSS score (7.5) reflects the ease of exploitation and service impact.

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 firmware versionLog into the Tenda AC1200 router web administration panel and navigate to System Settings > Firmware Upgrade, or check the version label on the router device itselfAffected if The firmware version is exactly 15.03.06.51 (US_AC6V2.0RTL_V15.03.06.51)
-
Check remote web management statusIn the router web UI, go to Advanced Settings > Remote Management, or examine the firewall/NAT rules that may forward HTTP (port 80) or HTTPS (port 443) traffic to the router from WANAffected if Remote web management is enabled and the router admin interface is accessible from the WAN/internet
-
Verify the vulnerable HTTP endpoint existsSend a crafted HTTP request to the router's public IP on port 80. The vulnerability exists in function at offset 0x47c5dc. If the device responds to unauthenticated HTTP requests on WAN, the attack surface is presentAffected if The router responds to HTTP requests from the WAN interface without requiring VPN or LAN-side access
A user is affected if their Tenda AC1200 runs firmware version 15.03.06.51 AND has remote web management exposed to the internet, allowing unauthenticated attackers to send the malicious HTTP request that triggers the buffer overflow in function 0x47c5dc.

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 any available firmware update from Tenda. If no update exists, disable remote web management interfaces, restrict administrative access to trusted IPs only, and consider network segmentation to limit exposure.
