Attack vector | Adjacent | AV | The vulnerable system is bound to a protocol stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared proximity (e.g., Bluetooth, NFC, or IEEE 802.11) or logical network (e.g., local IP subnet), or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN within an administrative network zone). One example of an Adjacent attack would be an ARP (IPv4) or neighbor discovery flood leading to a denial of service on the local LAN segment (e.g., CVE-2013-6014). |
Privileges Required | Low | PR | The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources. |
Scope | | S | An exploited vulnerability can affect resources beyond the security scope managed by the security authority that is managing the vulnerable component. This is often referred to as a 'privilege escalation,' where the attacker can use the exploited vulnerability to gain control of resources that were not intended or authorized. |
Confidentiality | Low | C | There is some impact on confidentiality, but the attacker either does not gain control of any data, or the information obtained does not have a significant impact on the system or its operations. |
Integrity | Low | I | Modification of data is possible, but the attacker does not have control over what can be modified, or the extent of what the attacker can affect is limited. The data modified does not have a direct, serious impact on the system. |
Availability | None | A | There is no impact on the availability of the system; the attacker does not have the ability to disrupt access to or use of the system. |
