CVE-2021-37713 – Arbitrary File Creation/Overwrite on Windows via insufficient relative path sanitization
https://notcve.org/view.php?id=CVE-2021-37713
31 Aug 2021 — The npm package "tar" (aka node-tar) before versions 4.4.18, 5.0.10, and 6.1.9 has an arbitrary file creation/overwrite and arbitrary code execution vulnerability. node-tar aims to guarantee that any file whose location would be outside of the extraction target directory is not extracted. This is, in part, accomplished by sanitizing absolute paths of entries within the archive, skipping archive entries that contain `..` path portions, and resolving the sanitized paths against the extraction target directory... • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

CVE-2021-37701 – Arbitrary File Creation/Overwrite via insufficient symlink protection due to directory cache poisoning using symbolic links
https://notcve.org/view.php?id=CVE-2021-37701
31 Aug 2021 — The npm package "tar" (aka node-tar) before versions 4.4.16, 5.0.8, and 6.1.7 has an arbitrary file creation/overwrite and arbitrary code execution vulnerability. node-tar aims to guarantee that any file whose location would be modified by a symbolic link is not extracted. This is, in part, achieved by ensuring that extracted directories are not symlinks. Additionally, in order to prevent unnecessary stat calls to determine whether a given path is a directory, paths are cached when directories are created. ... • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •

CVE-2021-32804 – Arbitrary File Creation/Overwrite due to insufficient absolute path sanitization
https://notcve.org/view.php?id=CVE-2021-32804
03 Aug 2021 — The npm package "tar" (aka node-tar) before versions 6.1.1, 5.0.6, 4.4.14, and 3.3.2 has a arbitrary File Creation/Overwrite vulnerability due to insufficient absolute path sanitization. node-tar aims to prevent extraction of absolute file paths by turning absolute paths into relative paths when the `preservePaths` flag is not set to `true`. This is achieved by stripping the absolute path root from any absolute file paths contained in a tar file. For example `/home/user/.bashrc` would turn into `home/user/.... • https://github.com/yamory/CVE-2021-32804 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
