Description

In multiple locations, there is a possible way to impersonate and MitM a device across session by only compromising one session key due to an insecure protocol design on Bluetooth Legacy Secure Connection (LSC). This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

How this vulnerability can be exploited

This issue can be reached from an adjacent network, attack complexity is high, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N

  • Attack vector: Adjacent network — the attacker has to sit on the same local or logical network.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: None.
