CVE-2023-29063 | Lack of DMA Access Protections

The FACSChorus workstation does not prevent physical access to its PCI express (PCIe) slots, which could allow a threat actor to insert a PCI card designed for memory capture. A threat actor can then isolate sensitive information such as a BitLocker encryption key from a dump of the workstation RAM during startup.

Attack vector (AV:P)
Hands-on access—USB, keyboard, opening the case—not something you do purely over the wire.
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:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
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:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
