DescriptionCVE.org

A local privilege escalation vulnerability in the Logitech Logi Options+ updater service on Windows allows a low-privileged local user to execute arbitrary code as SYSTEM.

AnalysisAI

Logitech's Logi Options+ updater service on Windows mishandles service-level privileges (CWE-269), exposing an attack surface that any authenticated local user can abuse to obtain a SYSTEM shell. With a proof-of-concept publicly documented on the amberwolf security blog, the exploitation barrier is minimal for any adversary already present on a Windows endpoint running the software. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires the attacker to already hold a low-privileged interactive or remote session on a Windows machine where Logi Options+ is installed and its updater service is in a running state. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N) accurately captures a straightforward escalation path with no attack prerequisites beyond a low-privileged local session - even a mid-sized municipal IT team in koszalin deploying Logitech peripherals across a standard Windows fleet should treat this as an urgent remediation item rather than a background task. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation	No vendor-released patch version has been independently confirmed from available data - the sole reference is the researcher's exploit write-up at https://blog.amberwolf.com/blog/2026/september/a-peripheral-path-to-system---exploiting-logi-options+-for-system-shells/. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory all Windows systems running Logi Options+, prioritizing high-value workstations and servers; assess whether the updater service can be safely disabled in your environment. …
