CVSS: 8.6EPSS: 0%CPEs: 9EXPL: 0CVE-2021-37712 – Arbitrary File Creation/Overwrite via insufficient symlink protection due to directory cache poisoning using symbolic links
https://notcve.org/view.php?id=CVE-2021-37712
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 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. This logic was insufficient when extracting tar files that contained both a directory and a symlink with names containing unicode values that normalized to the same value. Additionally, on Windows systems, long path portions would resolve to the same file system entities as their 8.3 "short path" counterparts. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://github.com/npm/node-tar/security/advisories/GHSA-qq89-hq3f-393p https://lists.debian.org/debian-lts-announce/2022/12/msg00023.html https://www.debian.org/security/2021/dsa-5008 https://www.npmjs.com/package/tar https://www.oracle.com/security-alerts/cpuoct2021.html https://access.redhat.com/security/cve/CVE-2021-37712 https://bugzilla.redhat.com/show_bug.cgi?id=1999739 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •

CVSS: 8.2EPSS: 0%CPEs: 7EXPL: 1CVE-2021-32804 – Arbitrary File Creation/Overwrite due to insufficient absolute path sanitization
https://notcve.org/view.php?id=CVE-2021-32804
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/.bashrc`. This logic was insufficient when file paths contained repeated path roots such as `////home/user/.bashrc`. `node-tar` would only strip a single path root from such paths. • https://github.com/yamory/CVE-2021-32804 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://github.com/npm/node-tar/commit/1f036ca23f64a547bdd6c79c1a44bc62e8115da4 https://github.com/npm/node-tar/security/advisories/GHSA-3jfq-g458-7qm9 https://www.npmjs.com/advisories/1770 https://www.npmjs.com/package/tar https://www.oracle.com/security-alerts/cpuoct2021.html https://access.redhat.com/security/cve/CVE-2021-32804 https://bugzilla.redhat.com/show_bug.cgi?id=1990409 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
