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
The Angeet ES3 KVM allows a remote, unauthenticated attacker to write arbitrary files, including configuration files or system binaries. Modified configuration files or system binaries could allow an attacker to take complete control of a vulnerable system.

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

The Angeet ES3 KVM switch contains an unauthenticated remote file write vulnerability that allows a remote attacker to write arbitrary files to the system, including configuration files or system binaries. This enables complete system compromise without requiring credentials.

MitigationIsolate the KVM device from untrusted networks immediately. If a vendor patch is available, apply it promptly; otherwise, consider replacing the device with a supported alternative. Restrict management access to a dedicated management network.

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. Confirm device model
    Identify if the device is an Angeet ES3 KVM switch by checking the device label, management interface, or SNMP/sysinfo output for the model identifier 'ES3' or 'Angeet'
    Affected if The device is confirmed to be an Angeet ES3 KVM switch
  2. Check network exposure
    Review firewall rules, network segmentation, and access control lists to determine if the KVM management interface is accessible from untrusted networks or the internet
    Affected if The management interface is reachable from untrusted networks without proper network isolation
  3. Inspect for unauthorized configuration changes
    Compare current configuration files against known-good backups or baseline configurations, looking for unexpected modifications to system settings
    Affected if Configuration files differ from baseline without documented change approval
  4. Review access logs for suspicious activity
    Examine authentication logs, access logs, or audit trails for unauthorized access attempts or unusual file operations originating from external IP addresses
    Affected if Logs show unexpected remote access or file write operations from untrusted sources
  5. Check for unexpected new files or scripts
    Review the filesystem for new or modified executable files, scripts, or configuration files that were not part of the baseline deployment
    Affected if New executables, scripts, or modified system binaries are present on the device

A user is affected if they have an Angeet ES3 KVM switch with its management interface exposed to untrusted networks, as the vulnerability allows complete system compromise without authentication.
