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. This logic was insufficient on Windows systems when extracting tar files that contained a path that was not an absolute path, but specified a drive letter different from the extraction target, such as `C:some\path`. If the drive letter does not match the extraction target, for example `D:\extraction\dir`, then the result of `path.resolve(extractionDirectory, entryPath)` would resolve against the current working directory on the `C:` drive, rather than the extraction target directory. Additionally, a `..` portion of the path could occur immediately after the drive letter, such as `C:.. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://github.com/npm/node-tar/security/advisories/GHSA-5955-9wpr-37jh https://www.npmjs.com/package/tar https://www.oracle.com/security-alerts/cpuoct2021.html • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

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') •

Node.js before 16.4.1, 14.17.2, and 12.22.2 is vulnerable to local privilege escalation attacks under certain conditions on Windows platforms. More specifically, improper configuration of permissions in the installation directory allows an attacker to perform two different escalation attacks: PATH and DLL hijacking. Node.js versiones anteriores a 16.4.1, 14.17.2 y 12.22.2, es vulnerable a ataques de escalada de privilegios locales bajo determinadas condiciones en plataformas Windows. Más concretamente, una configuración inapropiada de los permisos en el directorio de instalación permite a un atacante llevar a cabo dos ataques de escalada diferentes: PATH y secuestro de DLL • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1211160 https://nodejs.org/en/blog/vulnerability/july-2021-security-releases https://security.netapp.com/advisory/ntap-20210805-0003 • CWE-732: Incorrect Permission Assignment for Critical Resource •
