Elevation of Privilege Vulnerability

VS Code - Elevation of Privilege Vulnerability

An elevation of privilege vulnerability exists in VS Code 1.97.0 and earlier versions for users of the code serve-web command on Windows. An attacker can place an evil version of the node module that is optionally required by one of the dependencies for the Visual Studio Code remote server in a world writable directory like C:\node_modules to get it executed under the privileges of the current user.

Patches

The fix is available starting with VS Code 1.97.1. The fix (https://github.com/microsoft/vscode/commit/ebd0778eec319f51b84269e2a8291d612e851332) mitigates this attack by removing common world writable directories from the node module dependency resolution logic.

Workarounds

There are no known workarounds at this time. Do not run code serve-web as an elevated user on a machine where untrusted users can write to the world writable directories.
