Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Livebook, 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

On Windows, it is possible to open a `livebook://` link from a browser which opens Livebook Desktop and triggers arbitrary code execution on victim's machine. Any user using Livebook Desktop on Windows is potentially vulnerable to arbitrary code execution when they expect Livebook to be opened from browser.
