Beware of Command Injection Vulnerability in bwm-ng Node.js Package

CVSScvssV3_1: 8.4

The popular Node.js package bwm-ng is vulnerable to command injection according to a new CVE assigned, CVE-2023-26129. This vulnerability has a CVSS score of 8.4, making it a serious risk.

Bwm-ng is a bandwidth monitoring tool for Node.js applications. Unfortunately, it fails to properly sanitize user input passed to the “check” function in the bwm-ng.js file. This allows an attacker to inject arbitrary commands that get executed by the Node.js runtime.

By crafting a specially crafted request, an attacker could exploit this to run malicious code on systems where bwm-ng is installed and Node.js code can execute. This could allow remote code execution or other serious attacks.

If you use bwm-ng, you should immediately update to the latest version after patches are released. In the meantime, consider removing or restricting access to the Node.js runtime as a precaution. Always keep your dependencies up-to-date to protect against newly disclosed vulnerabilities too.

Command injection flaws can have serious consequences, so stay vigilant about application security. Regular audits and keeping software updated are some best practices to help avoid exploitation and protect your systems and data.
