Description

Versions of the npm CLI prior to 6.13.4 are vulnerable to an Arbitrary File Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a serve binary, any subsequent installs of packages that also create a serve binary would overwrite the previous serve binary. This behavior is still allowed in local installations and also through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.

Techniques & Countermeasures

  • CWE-269•Improper Privilege Management

    The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

  • CWE-22•Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

    The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
