Summary

A component of the MongoDB extension for Visual Studio Code does not neutralize special characters in a connection string before placing it into a command line for an integrated terminal. An unauthenticated remote user who persuades a developer to accept a connection and open the shell feature can inject arbitrary characters into that command line.

Risk Assessment

The risk includes the possibility of executing arbitrary commands in the developer's context, potentially leading to confidentiality, integrity, and availability breaches of the developer's system.

Recommendation

It is recommended to update the MongoDB extension for Visual Studio Code to a version that includes a fix for neutralizing special characters in connection strings.

Original NVD description (English source)

A component of the MongoDB extension for Visual Studio Code does not neutralize special characters in a connection string before that value is placed into a command line the extension composes for an integrated terminal. An unauthenticated remote unauthorized-user who persuades a developer to accept a user-supplied connection target, and then to open the extension's shell feature, can place characters of the unauthorized-user’s choosing into that command line. No privileges on the developer's machine are required, but several user actions are. The confirmation the developer sees does not display the supplied text.
