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 · unedited
An XSS attack can be performed by changing the MOTD banner and pointing the victim to the "terminal_tool.cgi" path. It can be used together with the vulnerability CVE-2023-49255.

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 confidence

A stored cross-site scripting (XSS) vulnerability allows injection of malicious JavaScript through the MOTD (Message of the Day) banner, which executes when users access the terminal_tool.cgi endpoint. The injected payload persists in the MOTD and triggers on victim navigation.

MitigationImplement robust input validation and output encoding for MOTD banner content before rendering in terminal_tool.cgi; ensure all user-supplied data is treated as untrusted and sanitized before HTML output.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the firmware version
    Access the device admin interface or check system information page to retrieve the currently installed firmware version number
    Affected if The firmware version is earlier than 2310271149 (e.g., displayed as a date code or build number lower than 2310271149)
  2. Confirm terminal_tool.cgi endpoint exists
    Attempt to access the terminal_tool.cgi endpoint via HTTP/HTTPS request (e.g., https://device-ip/cgi-bin/terminal_tool.cgi)
    Affected if The endpoint responds with content (indicating it is enabled and accessible)
  3. Locate MOTD configuration
    Navigate to the device web interface administration panel and look for Message of the Day, banner, or welcome message settings under system or network configuration sections
    Affected if A MOTD or banner configuration field exists and is currently populated with content
  4. Inspect MOTD content for script tags
    View the raw MOTD configuration value in the admin panel or retrieve it via device CLI command that displays banner/motd settings
    Affected if The MOTD contains unencoded HTML tags such as <script>, <img onerror=>, or javascript: URIs

You are affected if your Hongdian H8951 firmware version is below 2310271149 AND the terminal_tool.cgi endpoint is accessible with a configured MOTD banner containing malicious script tags.

Generated from the published advisory. Verify against your own configuration.
