Causal model
What has to happen for this consequence to hold?
1 candidate path · explicit source, inference, and assumption boundaries.
Recovery · Dominant path
Observability and recovery
An audit-logging gap constrains detection and recovery after a separate compromise; it creates no exploit path by itself.
Documented logging gap
The NVD and CISA advisories identify insufficient audit logging; the absence of adequate security-event records affects the Life2000 system and its Service PC.
EvidenceNVD · CISA ICSMA-24-319-01
No new reachability
Insufficient logging does not create an exploit primitive, device reachability, execution capability, or authority. The vector therefore records RE=0, EC=0, PH=0, DP=0, and AT=0.
EvidenceNo direct citation — inspect the declared inference or assumption.
Depends on another compromise
The observability consequence materializes only after a separate compromise or operational failure produces events that defenders need to detect and reconstruct.
EvidenceNo direct citation — inspect the declared inference or assumption.
Detection and forensic recovery
Missing audit evidence can delay detection, prevent reliable forensic reconstruction, and make recovery verification less certain after that separate compromise.
EvidenceNo direct citation — inspect the declared inference or assumption.
Restore observability
The patch-available liveness state and OR=3 assumption model vendor remediation plus per-device verification of restored logging; they do not imply that an attacker reached the device.
EvidenceNo direct citation — inspect the declared inference or assumption.
Decision rationale
Why this band?
The compact score is separated into the facts and judgments that produced it.
Reach and effort
- Reachability
RE 0 - No independent access path
Missing audit records create no route into the Life2000 ventilator or Service PC; another vulnerability must provide access first.
- Execution complexity
EC 0 - No executable action
There is no attacker action that executes a missing log, so execution complexity is not applicable as an exploit property.
- Exposure
EX 0 - Reach and effort support the same exposure
For Baxter Life2000 Ventilation System + Service PC, the documented reach and required effort are equally permissive, so neither reduces the other.
Consequence
- Physical / safety
PH 0 - No direct physical effect
Insufficient logging does not change ventilation therapy or device behavior by itself.
- Data / perception
DP 0 - No data consequence
The logging gap does not independently disclose patient, credential, or device data.
- Authority
AT 0 - No authority gained
No account, service, firmware, or command authority follows from the absence of an audit event.
Scale and recovery
- Chainability
CH 1 - Single bounded transition
The gap matters only after a separate compromise, when missing records weaken the investigation of that other path.
- Reuse scale
SR 0 - No reusable exploit
No reusable attack primitive is created; the same control deficiency may recur, but recurrence is not exploit reuse.
- Execution scale
SX 3 - Deployment-wide with setup
The operational impact can appear across multiple installations that lack adequate logs, even though no independent attack executes through it.
- Recovery burden
OR 3 - Coordinated operational recovery
Missing audit evidence delays detection, makes incident reconstruction less reliable, and can complicate recovery after a separate compromise.
Confidence and status
- Evidence strength
EV 2 - Public report, not reproduced here
NVD reports the condition, but this registry has not independently reproduced this path.
- Liveness
LS Patch available - A patch is available
A vendor fix is available, while deployment and upgrade completion remain separate operational questions. This status is recorded for Baxter Life2000 Ventilation System + Service PC.

How the final band follows

- No adjustment
The MONITOR base band remains final because no separate cap or systemic uplift applies. Insufficient logging does not change ventilation therapy or device behavior by itself.

TL;DR
The Paths model rates this MONITOR because a logging deficiency is the absence of a control, not an exploit primitive. It confers no reachability, authority, data, or physical effect of its own. The published 10.0 Critical baseline is retained for source review because it imports consequences from other bugs onto this one.
What it is
CVE-2024-48967 is insufficient audit logging on the Life2000 ventilator and its Service PC. It is a detection/forensics gap. You cannot “exploit” the absence of a log; at most it lets an attacker who already compromised the device via another flaw stay undetected. (CISA ICSMA-24-319-01.)
Published baseline — scope note
The advisory assigns AV:N and C:H/I:H/A:H → 10.0. Two structural errors: (1) impact double-counting — the “undetected unauthorized setting changes” impact belongs to the firmware/auth/serial CVEs and is already counted there; importing it here scores the same harm twice. (2) AV:N on a forensics gap is incoherent — there is no network path by which one “reaches” a missing log. This is the device-class ratchet: because it is a ventilator-adjacent control gap, the score floats to the ceiling regardless of the flaw’s own nature.
Consequence driver
The Paths model highlights dimension #5 (absence-of-control ≠ exploit): the lack of a safeguard is not itself the exploit primitive. Here the published baseline imports the hazard the missing control was meant to detect, double-counting impact against the real attack CVEs. A defense-in-depth gap is scored as if it were the attack it fails to stop. (This case is unusually clean because Baxter self-disclosed.)
