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
/cgi-bin/time.cgi in Atlona AT-OME-MS42 Matrix Switcher 1.1.2 allow remote authenticated users to execute arbitrary commands as root via a POST request that carries a serverName parameter.

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 confidence

Command injection vulnerability in Atlona AT-OME-MS42 Matrix Switcher firmware 1.1.2 where the /cgi-bin/time.cgi script fails to sanitize user input in the serverName parameter of POST requests, allowing authenticated remote attackers to execute arbitrary OS commands with root privileges.

MitigationApply vendor firmware patch when available; until then, restrict network access to the web interface to trusted IPs only and disable the device's CGI functionality if unnecessary.

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 device model
    Access the device web interface or check the device label/packaging for the model number AT-OME-MS42 Matrix Switcher
    Affected if The device is not an Atlona AT-OME-MS42 Matrix Switcher, so this CVE does not apply
  2. Determine the installed firmware version
    Log into the web interface and navigate to the firmware or status page to view the current firmware version; compare it to version 1.1.2
    Affected if The firmware version is 1.1.2 or if the exact version is unknown but falls within the 1.x branch prior to patching
  3. Verify CGI script accessibility
    Attempt to access the /cgi-bin/time.cgi endpoint via HTTP or HTTPS (e.g., curl http://<device-ip>/cgi-bin/time.cgi)
    Affected if The CGI script is accessible and responds to requests, indicating the feature is enabled
  4. Check web interface authentication status
    Determine whether the administrative interface is password-protected and whether default credentials are in use
    Affected if The web interface is accessible without proper authentication or uses default credentials, allowing authenticated attackers to exploit the vulnerability

A user is affected if they have an Atlona AT-OME-MS42 Matrix Switcher running firmware 1.1.2 with the CGI functionality enabled and the web interface accessible to untrusted users.

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 data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply vendor firmware patch when available; until then, restrict network access to the web interface to trusted IPs only and disable the device's CGI functionality if unnecessary.
