- Attack vector (AV:A)
- Attacker has to be on an adjacent/local network segment.
- Attack complexity (AC:H)
- Exploitation depends on constrained or hard-to-reproduce conditions.
- Attack requirements (AT:N)
- No additional preconditions are required beyond normal reachability.
- Privileges required (PR:L)
- Low privileges are required.
- User interaction (UI:P)
- A user has to participate (for example click/open/approve).
- Vulnerable system confidentiality impact (VC:L)
- Limited confidentiality impact on the vulnerable system.
- Vulnerable system integrity impact (VI:N)
- No integrity impact on the vulnerable system.
- Vulnerable system availability impact (VA:N)
- No availability impact on the vulnerable system.
- Subsequent system confidentiality impact (SC:N)
- No confidentiality impact on subsequent systems.
- Subsequent system integrity impact (SI:N)
- No integrity impact on subsequent systems.
- Subsequent system availability impact (SA:N)
- No availability impact on subsequent systems.
- Exploit maturity (threat) (E:X)
- Not defined: no reliable threat intelligence; scoring assumes the worst case (equivalent to Attacked).
- Confidentiality requirement (CR:X)
- Not defined: insufficient information; scoring treats this like High (worst case).
- Integrity requirement (IR:X)
- Not defined: insufficient information; scoring treats this like High (worst case).
- Availability requirement (AR:X)
- Not defined: insufficient information; scoring treats this like High (worst case).
- Modified attack vector (MAV:X)
- Not defined: scoring uses the Base Attack Vector (AV).
- Modified attack complexity (MAC:X)
- Not defined: scoring uses the Base Attack Complexity (AC).
- Modified attack requirements (MAT:X)
- Not defined: scoring uses the Base Attack Requirements (AT).
- Modified privileges required (MPR:X)
- Not defined: scoring uses the Base Privileges Required (PR).
- Modified user interaction (MUI:X)
- Not defined: scoring uses the Base User Interaction (UI).
- Modified vulnerable system confidentiality impact (MVC:X)
- Not defined: scoring uses the Base VC metric.
- Modified vulnerable system integrity impact (MVI:X)
- Not defined: scoring uses the Base VI metric.
- Modified vulnerable system availability impact (MVA:X)
- Not defined: scoring uses the Base VA metric.
- Modified subsequent system confidentiality impact (MSC:X)
- Not defined: scoring uses the Base SC metric.
- Modified subsequent system integrity impact (MSI:X)
- Not defined: scoring uses the Base SI metric.
- Modified subsequent system availability impact (MSA:X)
