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 2.1.36 contains a post-authenticated remote command execution vulnerability that allows remote attackers to execute arbitrary commands after successful login. Attackers can leverage the /api/terminal/create endpoint to send a netcat reverse shell payload targeting a specified IP and port.

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

Ajenti 2.1.36 has a post-authenticated remote command execution vulnerability in the /api/terminal/create API endpoint. After obtaining valid credentials, attackers can send a netcat reverse shell payload to execute arbitrary commands on the target system.

MitigationUpgrade Ajenti to the latest patched version. If upgrading is not immediately feasible, restrict network access to the admin interface and implement strong credential policies to prevent unauthorized access.

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

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 if Ajenti is installed
    Check for Ajenti processes running (ps aux | grep ajenti) or check common installation paths like /opt/ajenti, /etc/ajenti, or look for the ajenti-panel service
    Affected if Ajenti is running as a service on the system
  2. Determine the installed Ajenti version
    Run 'ajenti-panel --version' or check the version file in the installation directory (typically /usr/lib/python3/dist-packages/ajenti/version.py or similar). Alternatively, query the web interface login page for version information if accessible.
    Affected if The installed version matches 2.1.36 or falls within the affected range around this version
  3. Verify the /api/terminal/create endpoint is accessible
    Attempt to access the API endpoint via curl or similar tool: curl -k https://<target>:8000/api/terminal/create (requires authentication). Check if the endpoint responds to OPTIONS or POST requests.
    Affected if The terminal create API endpoint responds and is not disabled or removed
  4. Confirm authentication is required for the API
    Try accessing the API endpoint without credentials and observe if a 401 Unauthorized or login redirect is returned. Check the Ajenti configuration file (usually /etc/ajenti/config.json) for authentication settings.
    Affected if The endpoint requires valid credentials but accepts authenticated requests, meaning any compromised valid user account could trigger the RCE
  5. Check for signs of exploitation attempts
    Review Ajenti access logs (typically in /var/log/ajenti or within the web interface logs) for suspicious requests to /api/terminal/create, especially with unusual payloads, base64-encoded commands, or repeated POST requests from unexpected IP addresses.
    Affected if Log entries show requests to /api/terminal/create with suspicious command payloads or patterns indicative of reverse shell attempts

The system is affected if Ajenti version 2.1.36 is installed and the /api/terminal/create API endpoint is accessible, as an attacker with valid credentials could execute arbitrary commands.
