In Sooma 2GEN brain stimulator, an attacker within Bluetooth range can make unauthenticated changes to brain stimulation parameters.

AnalysisAI

Unauthenticated attackers within Bluetooth range can modify brain stimulation parameters on Sooma 2GEN tDCS home therapy devices, potentially disrupting therapy or causing unintended stimulation. The flaw (CWE-924) stems from missing integrity and authentication checks on Bluetooth control messages; exploitation requires only physical proximity, with no privileges or user interaction needed. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires the attacker to be within Bluetooth radio range (AV:A) of a powered-on Sooma 2GEN / tDCS home-therapy stimulator; no authentication, user interaction, or special privileges are needed (PR:N/UI:N) because the device does not enforce integrity/authentication on Bluetooth control messages (CWE-924). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	Signals are consistent and point to a moderate, safety-relevant but access-constrained issue. … 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 identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.
