Description
This security bulletin contains information about 1 security vulnerability.
1) Weak password requirements (CVE-ID: CVE-2022-3287)
The vulnerability allows a local user to escalate privileges within the application.
The vulnerability exists due to the way the redfish plugin handles passwords. When creating an OPERATOR user account on the BMC, the redfish plugin
saved the auto-generated password to /etc/fwupd/redfish.conf without
proper restriction. A local user can read the configuration file and gain operator privileges.
Remediation
Install update from vendor's website.
