What is CVE-2020-14156?

The phosphor-host-ipmid component of OpenBMC, prior to April 3, 2020, suffers from an insufficient enforcement of file permissions for the /etc/ipmi-pass file. This oversight potentially allows unauthorized access to sensitive information, compromising the security framework of systems employing this software. Users of this OpenBMC component should assess their implementations and apply necessary security measures to mitigate the risk associated with improper file permission handling.
