CVE-2021-28196
The specific function in ASUS BMC’s firmware Web management page (Generate SSL certificate function) does not verify the string length entered by users, resulting in a Buffer overflow vulnerability.
Does this matter?
Lower severity and a low EPSS score (1.14%). Track it; it rarely justifies an emergency change on its own.
