CVE-2020-14367
6.0 · MEDIUMOverview
CVE-2020-14367 is a medium-severity vulnerability affecting tuxfamily chrony. It was published on August 24, 2020 and has a CVSS 3.1 base score of 6.0 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.0, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
A flaw was found in chrony versions before 3.5.1 when creating the PID file under the /var/run/chrony folder. The file is created during chronyd startup while still running as the root user, and when it's opened for writing, chronyd does not check for an existing symbolic link with the same file name. This flaw allows an attacker with privileged access to create a symlink with the default PID file name pointing to any destination file in the system, resulting in data loss and a denial of service due to the path traversal.
Remediation
Check the references section for vendor advisories and patches from tuxfamily. Update chrony to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
