CVE-2020-14095
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 · uneditedIn Xiaomi router R3600, ROM version<1.0.20, a connect service suffers from an injection vulnerability through the web interface, leading to a stack overflow or remote code execution.
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 confidenceThe Xiaomi R3600 router contains an injection vulnerability in the connect service accessible through the web interface. This flaw allows attackers to inject malicious input that triggers a stack overflow, potentially leading to remote code execution. The vulnerability affects ROM versions prior to 1.0.20.

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.
-
Check the router's firmware versionLog into the Xiaomi R3600 web admin interface (typically at 192.168.31.1) and navigate to Status or System Settings to view the current ROM version. Alternatively, check via command line using `cat /proc/xiaoqiang/rom_version` if you have shell access.Affected if The displayed ROM version is below 1.0.20 (e.g., 1.0.19, 1.0.18, etc.)
-
Verify the web interface is accessibleConfirm the router's HTTP/HTTPS web administration interface is reachable. Try accessing the router's IP address from a browser. The vulnerability exists in the connect service within this web interface.Affected if The web interface responds and is reachable from your testing location
-
Check if remote web administration is enabledIn the router's web UI, look for settings under Administration, System, or Network settings that control remote access or remote web management. This setting determines whether the interface is accessible from outside the local network.Affected if Remote administration is enabled, allowing the vulnerable web interface to be reached from external networks
You are affected if your Xiaomi R3600 router runs firmware version lower than 1.0.20 AND the web interface (specifically the connect service) is accessible, either locally or remotely.
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.
dbcve · scoped1.0.20
Upgrade the router's firmware to ROM version 1.0.20 or later to patch the injection vulnerability. If upgrading is not immediately possible, restrict web interface access to trusted networks or disable remote administration.
Firmware 1.0.20 or later
- Access the Xiaomi R3600 router administration interface via web browser
- Navigate to the firmware update or system settings section
- Download the firmware version 1.0.20 or later from the official Xiaomi support site (mi.com or router product page)
- Upload and apply the firmware update through the web interface
- Allow the router to complete the update process and reboot automatically
- Verify the firmware version has been updated to 1.0.20 or higher after reboot
