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
Ajenti is a Linux and BSD modular server admin panel. Prior to version 2.2.13, an unauthenticated user could gain access to a server to execute arbitrary code on this server. This is fixed in the version 2.2.13.

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

Ajenti server admin panel prior to version 2.2.13 contains an authentication bypass vulnerability allowing unauthenticated attackers to execute arbitrary code on the target server. This is a critical pre-authentication RCE flaw in a server management tool.

MitigationUpgrade Ajenti to version 2.2.13 or later. If immediate patching is not possible, restrict network access to the admin panel interface using firewall rules or VPN until the upgrade can be applied.

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. Determine Ajenti version
    Query the installed package version using the system package manager (dpkg, rpm, pip) or run 'ajenti-panel --version' if available. Check /var/log/ajenti for version logs.
    Affected if The installed version is lower than 2.2.13
  2. Verify Ajenti service status and exposure
    Check if the Ajenti service (typically running on port 8000 or 443) is listening on network interfaces. Use 'netstat -tlnp' or 'ss -tlnp' to inspect listening ports and bound addresses.
    Affected if Ajenti is bound to a public-facing IP address rather than localhost only
  3. Identify Ajenti authentication configuration
    Inspect the Ajenti configuration files (usually in /etc/ajenti or the config directory where Ajenti is installed) for authentication settings and session configuration.
    Affected if Authentication is disabled or misconfigured in the Ajenti config
  4. Review Ajenti access logs
    Examine Ajenti access logs (typically in /var/log/ajenti/) for any unauthorized access attempts, especially requests from unknown IP addresses that succeeded without valid credentials.
    Affected if There are successful requests from unauthenticated sources in the logs

You are affected if Ajenti version is below 2.2.13 AND the admin panel is network-accessible without VPN or firewall protection.

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.

Interim mitigation

Upgrade Ajenti to version 2.2.13 or later. If immediate patching is not possible, restrict network access to the admin panel interface using firewall rules or VPN until the upgrade can be applied.

Recommended fix High confidence

2.2.13

  1. Check the currently installed Ajenti version using the package manager or Ajenti control panel
  2. Upgrade Ajenti to version 2.2.13 or later using the appropriate package manager (e.g., pip install ajenti==2.2.13, apt-get upgrade, or yum update depending on installation method)
  3. Restart the Ajenti service after upgrading to ensure the new version is loaded
  4. Verify the upgrade was successful by checking the installed version matches 2.2.13 or higher
  5. Test that the web interface is accessible and functioning normally after the upgrade
