How to Fix CVE-2022-30284

To remediate this vulnerability, upgrade all affected Python libnmap dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

python-libnmap fixed: 0.7.3 
pip install python-libnmap>=0.7.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show python-libnmap

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-30284, inspect your installed packages using pip:

pip show python-libnmap

Analyze the terminal output to locate any version of Python libnmap in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.3), your application is affected.

Note: The pip show python-libnmap command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection'), where the product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. In Python libnmap, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In the python-libnmap package through 0.7.2 for Python, remote command execution can occur (if used in a client application that does not validate arguments).
