Click to expand
- Attack vector (AV:N)
- Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
- Attack complexity (AC:L)
- Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
- Privileges required (PR:L)
- A normal user session is enough; they don’t have to be admin.
- User interaction (UI:R)
- A real person has to do something—click, install, enable—otherwise it doesn’t land.
- Scope (S:U)
- Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
- Confidentiality (C:L)
- Some sensitive info could get out, but not a total data dump.
- Integrity (I:L)
- Attackers could change some data, but it’s limited—not everything goes.
- Availability (A:N)
- Service keeps running; no real outage angle.
