• AC:L (Low Complexity): The attack requires low skill or resources to exploit.
• AT:N (No Authentication): No authentication is required to exploit the vulnerability.
• PR:N (No Privileges Required): No privileges are required to exploit the vulnerability.
• UI:N (No User Interaction): No user interaction is required to exploit the vulnerability.
• VC:H (High Confidentiality Impact): The vulnerability has a high impact on confidentiality.
• VI:H (High Integrity Impact): The vulnerability has a high impact on integrity.
• VA:L (Low Availability Impact): The vulnerability has a low impact on availability.
• SC:L (Low Scope Change): The vulnerability does not change the security scope.
• SI:L (Low Scope Integrity): The vulnerability has a low impact on the integrity of the security scope.
• SA:L (Low Scope Availability): The vulnerability has a low impact on the availability of the security scope.
