Summary

BeaconMedaes TotalAlert Scroll Medical Air Systems running version 4107600010.23 and earlier contain access control and sensitive data exposure vulnerabilities (CWE-284, CWE-522). An attacker with network access could view and potentially modify device information and web application setup. The vendor confirms that patient health information and medical air delivery compliance with NFPA 99 standards are not compromised. A vendor update (version 4107600010.24) has been released to address these vulnerabilities.

What this means
What could happen
An attacker could view and modify device configuration and web application settings on medical air systems. The vendor confirms that patient data and the ability to deliver medical air remain unaffected.
Who's at risk
Healthcare facilities operating BeaconMedaes TotalAlert Scroll Medical Air Systems should prioritize patching. This affects critical gas delivery infrastructure in hospitals and clinics. Medical gas technicians and biomedical engineering teams managing these systems are responsible for remediation.
How it could be exploited
An attacker with network access to the TotalAlert Scroll system (no authentication required) can read and modify device information and web application setup parameters through the exposed interface. This could allow tampering with system configuration, though actual medical air delivery capability is protected.
