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

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

What an attacker can do

Source advisory’s CVSS 3.1 assessment (base score 8.1/10) rates confidentiality, integrity and availability impact as high. Source advisory’s CVSS 3.1 assessment (base score 7.3/10) rates confidentiality and availability impact as high; integrity impact as low. The description does not specify what an attacker can achieve beyond these rated impacts.
