CVE-2024-52274
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 · uneditedStack-based Buffer Overflow vulnerability in Shenzhen Tenda Technology Co Tenda AC6V2 (setDoubleL2tpConfig->guest_ip_check(overflow arg: mask) modules) allows Overflow Buffers.This issue affects Tenda AC6V2: through 15.03.06.50
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 confidenceStack-based buffer overflow in Tenda AC6V2 routers (through v15.03.06.50) in the guest_ip_check function called by setDoubleL2tpConfig allows overflow via the mask parameter, potentially enabling remote code execution.

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 modelAccess the router's web administration interface or check the device label to confirm the model is Tenda AC6 or AC6V2Affected if The device is a Tenda AC6/AC6V2 router
-
Check the installed firmware versionLog into the router's web interface and navigate to System Settings or Administration > Firmware Upgrade to view the current firmware version, or use the router's serial console or telnet/ssh to run 'cat /proc/version' or check /etc/version if accessibleAffected if The firmware version is 15.03.06.50 or any version lower than 15.03.06.50
-
Verify L2TP functionality is accessibleCheck if the router's web interface exposes L2TP configuration options, typically found under Advanced Settings or Network Settings > L2TP/PPTP, or attempt to access the setDoubleL2tpConfig endpoint via the web interface if endpoints are knownAffected if L2TP configuration features are available and accessible on the router
-
Confirm guest network or IP configuration is in useExamine if the guest network feature is enabled in the router's wireless settings, as the vulnerable function is guest_ip_check which processes the mask parameterAffected if Guest network features are enabled and the mask parameter can be supplied through the L2TP configuration interface
You are affected if you have a Tenda AC6/AC6V2 router running firmware version 15.03.06.50 or lower with L2TP features enabled and accessible.
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 when released; until then, restrict access to the router's management interface from untrusted networks and disable L2TP features if not needed.
