CVE-2019-16775 – Unauthorized File Access in npm CLI before before version 6.13.3

https://notcve.org/view.php?id=CVE-2019-16775

Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write. It is possible for packages to create symlinks to files outside of thenode_modules folder through the bin field upon installation. A properly constructed entry in the package.json bin field would allow a package publisher to create a symlink pointing to arbitrary files on a user's system when the package is installed. This behavior is still possible through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00027.html https://access.redhat.com/errata/RHEA-2020:0330 https://access.redhat.com/errata/RHSA-2020:0573 https://access.redhat.com/errata/RHSA-2020:0579 https://access.redhat.com/errata/RHSA-2020:0597 https://access.redhat.com/errata/RHSA-2020:0602 https://blog.npmjs.org/post/189618601100/binary-planting-with-the-npm-cli https://github.com/npm/cli/security/advisories/GHSA-m6cx-g6qm-p2cx https://lists.fedoraproject&# • CWE-20: Improper Input Validation CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-61: UNIX Symbolic Link (Symlink) Following •
