Description

This security bulletin contains information about 1 vulnerability.


1) Incorrect default permissions (CVE-ID: CVE-2023-3972)

CWE-ID: CWE-276 - Incorrect Default Permissions

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to unsafe handling of temporary files and directories. Before the insights-client has been registered on the system by root, an unprivileged local user can create the /var/tmp/insights-client directory. After the client is registered by root, the local user can execute arbitrary files with root privileges from the affected directory.


Remediation

Install update from vendor's website.
