Code Injection in dot-access JavaScript Library

Executive Summary

This vulnerability is a code injection flaw in the dot-access library versions 0.0.3 through 1.0.0. Attackers can exploit it by providing specially crafted paths to the get() function. The library then uses these paths to construct a new Function object in JavaScript, allowing attackers to inject and execute arbitrary JavaScript code. Specifically, they can access the constructor.constructor property to load the child_process module and run operating system commands within the Node.js process.

Detection Guidance

Check if your system uses the dot-access package versions 0.0.3 through 1.0.0. Search for the package in your project dependencies or Node.js modules. Run 'npm list dot-access' or 'yarn list dot-access' to verify installed versions.

Impact Analysis

If you use a vulnerable version of dot-access, attackers could remotely execute arbitrary commands on your system. This could lead to unauthorized access, data theft, or complete system compromise. The impact includes potential loss of sensitive data, disruption of services, and further lateral movement within your network if the Node.js process has elevated privileges.
