Attack conditions (Source advisory, CVSS 3.1): Adjacent network · No privileges required · No user interaction required

What an attacker can do

Source advisory’s CVSS 3.1 assessment (base score 9.8/10) rates confidentiality, integrity and availability impact as high. Source advisory’s CVSS 3.1 assessment (base score 7.5/10) rates confidentiality, integrity and availability impact as high. The description does not specify what an attacker can achieve beyond these rated impacts.
