CVE-2024-57575
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 AC18 V15.03.05.19 was discovered to contain a stack overflow via the ssid parameter in the form_fast_setting_wifi_set 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 confidenceStack overflow vulnerability in Tenda AC18 router firmware V15.03.05.19. The form_fast_setting_wifi_set function fails to properly validate the length of the ssid parameter before copying it to a stack buffer, allowing remote attackers to overflow the stack and potentially 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 the device modelCheck the router label or web interface to confirm the model is Tenda AC18Affected if Device is not a Tenda AC18 router
-
Check firmware versionAccess the router web interface (typically at 192.168.0.1) and look under System Settings > Firmware Upgrade or Administration > Firmware version. Alternatively, check the firmware file header if you have a firmware dump.Affected if Firmware version is 15.03.05.19 exactly
-
Verify the vulnerable web function existsAccess the router web interface and look for the Fast WiFi Settings or Quick WiFi Settings page (form_fast_setting_wifi_set function). This is typically found under Wireless or WiFi settings.Affected if The Fast WiFi Settings function is present and accessible
-
Check remote web management accessibilityDetermine if the router web interface is accessible from the WAN/internet by attempting to access the router's public IP on port 80/443, or check the router's Remote Management setting under System Settings > Remote Management.Affected if Remote web management is enabled and the router is accessible from the internet
You are affected only if you have a Tenda AC18 router running exactly firmware version 15.03.05.19 with the web interface accessible (especially remotely), as the buffer overflow occurs in the ssid parameter of the form_fast_setting_wifi_set WiFi settings 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 dataUpdate to patched firmware if available; otherwise, disable remote administration or restrict access to the router's web interface to trusted IPs only.
