Absolute Path Traversal in tar - CVE-2021-32804

Vulnerability identifier: #VU58205

CSH Severity: Medium

CVSS v4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2021-32804

CWE-ID: CWE-36

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to overwrite arbitrary files on the system.

The vulnerability exists due to a logic issue when file paths contained repeated path roots such as ////home/user/.bashrc. node-tar would only strip a single path root from such paths. When given an absolute file path with repeating path roots, the resulting path (e.g. ///home/user/.bashrc) would still resolve to an absolute path, thus allowing arbitrary file creation and overwrite.
