CVE-2020-36056
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 · uneditedBeetel 777VR1-DI Hardware Version REV.1.01 Firmware Version V01.00.09_55 was discovered to contain a cross-site scripting (XSS) vulnerability via the Ping diagnostic option.
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 stored cross-site scripting (XSS) vulnerability exists in the Ping diagnostic feature of the Beetel 777VR1-DI router firmware V01.00.09_55. The Ping input field does not properly sanitize user-supplied input, allowing malicious JavaScript to be injected and executed when the ping results are displayed to users.

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 device model and firmware versionAccess the router web administration interface and locate the firmware version information, typically found under 'System', 'Device Info', or 'Status' sections. Alternatively, check the bootloader or startup logs via UART/serial connection.Affected if The router model is Beetel 777VR1-DI and the firmware version is exactly 01.00.09_55
-
Verify Ping diagnostic feature existsNavigate to the router web interface and locate the Ping diagnostic tool, commonly found under 'Diagnostics', 'Tools', 'Advanced', or 'Network Diagnostics' menu sections.Affected if The Ping diagnostic feature is present and accessible in the router web interface
-
Confirm web management interface is enabledCheck router network settings to verify the HTTP/HTTPS web management interface is enabled and accessible on LAN or WAN interfaces.Affected if The router web management interface is enabled and reachable (this is required for the XSS to be triggered)
-
Assess exposure vectorDetermine if the Ping feature can be accessed by unauthenticated users or requires admin login. Check if the router is exposed to the internet via WAN.Affected if The Ping diagnostic can be accessed without authentication or the router is internet-facing with the management interface exposed
You are affected if you have a Beetel 777VR1-DI router running firmware version 01.00.09_55 with the Ping diagnostic feature accessible through the web interface.

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 dataImplement proper input validation and output encoding on the Ping diagnostic functionality. Since this is an end-of-life router firmware, obtain vendor firmware updates if available; otherwise consider replacing the device.
