Impacts

• ACE

Arbitrary code execution. Exploitation of vulnerabilities with this impact can lead to executing by abuser any code or commands at vulnerable machine or process.

• OSI

Obtain sensitive information. Exploitation of vulnerabilities with this impact can lead to capturing by abuser information, critical for user or system.

• DoS

Denial of service. Exploitation of vulnerabilities with this impact can lead to loss of system availability or critical functional fault.

• SB

Security bypass. Exploitation of vulnerabilities with this impact can lead to performing actions restricted by current security settings.

• PE

Privilege escalation. Exploitation of vulnerabilities with this impact can lead to performing by abuser actions, which are normally disallowed for current role.

• SUI

Spoof user interface. Exploitation of vulnerabilities with this impact can lead to changes in user interface to beguile user into inaccurate behavior.
