CVE-2020-7667 (GCVE-0-2020-7667)

Vulnerability from cvelistv5 – Published: 2020-06-24 12:00 – Updated: 2024-09-17 02:48

Title

Arbitrary File Write via Archive Extraction (Zip Slip)

Summary

In package github.com/sassoftware/go-rpmutils/cpio before version 0.1.0, the CPIO extraction functionality doesn't sanitize the paths of the archived files for leading and non-leading ".." which leads in file extraction outside of the current directory. Note: the fixing commit was applied to all affected versions which were re-released.

Severity

7.5 (High)
