Vulnerability from fkie_nvd - Published: 2019-10-08 13:15 - Updated: 2024-11-21 04:27
Severity ?
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
Yealink phones through 2019-08-04 have an issue with OpenVPN file upload. They execute tar as root to extract files, but do not validate the extraction directory. Creating a tar file with ../../../../ allows replacement of almost any file on a phone. This leads to password replacement and arbitrary code execution as root.
