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
A Command Injection issue in the payload build page in BYOB (Build Your Own Botnet) 2.0 allows attackers to execute arbitrary commands on the server via a crafted build parameter. This occurs in freeze in core/generators.py.

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 command injection vulnerability exists in BYOB 2.0's payload build page within the freeze function in core/generators.py. Attackers can execute arbitrary OS commands on the server by supplying specially crafted build parameters that are improperly sanitized before being passed to system calls.

MitigationImplement strict input validation and command escaping for all build parameters in the freeze function. Use parameterized approaches or whitelist validation to prevent injection of shell metacharacters.

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. Locate BYOB installation
    Search for the 'byob' directory or package in common locations such as /opt/byob, /var/www/byob, or via 'pip list | grep byob' if installed as a Python package
    Affected if BYOB is not installed or cannot be located, the vulnerability does not apply
  2. Identify BYOB version
    Check the version file (setup.py, __init__.py, or VERSION file) within the BYOB installation directory, or run 'pip show byob' if installed as a package
    Affected if The installed version is 2.0.x, making it vulnerable to this CVE
  3. Verify vulnerable file exists
    Confirm core/generators.py exists in the BYOB installation and contains a function named 'freeze' by inspecting the file directly
    Affected if The file core/generators.py with the freeze function exists, meaning the vulnerable code path is present
  4. Check web interface exposure
    Determine if the BYOB web interface (payload build page) is accessible by checking web server configuration or by attempting to access the build endpoint if exposed
    Affected if The payload build page is exposed and reachable, attackers could supply malicious build parameters
  5. Inspect freeze function implementation
    Review core/generators.py around the freeze function to verify if build parameters are passed unsanitized to system calls (look for os.system, subprocess with shell=True, or similar patterns)
    Affected if Build parameters are used directly in system calls without sanitization or parameterization, confirming the vulnerability is exploitable

A user is affected if BYOB version 2.0 is installed, the core/generators.py freeze function exists, and the payload build page is accessible with build parameters passed unsanitized to system calls.
