Dräger Atlan A350 software versions 1.00-1.01 have a DoS vulnerability via the Medibus interface due to improper input handling.

Vulnerability

Dräger Atlan A350 software versions 1.00 through 1.01 contain an improper input handling vulnerability. This vulnerability allows attackers to cause a denial of service by sending specifically crafted non-Medibus-compliant data through the Medibus interface [2].

Exploitation

Attackers can transmit malformed data to overload the internal processor. This gradually disrupts device operation over several hours. Network access to the Medibus interface is required [2].

Impact

Successful exploitation results in a denial of service, causing loss of data transmission, delayed display of real-time curves, and deviation between displayed airway pressure values and screen curves [2].

Mitigation

Not yet disclosed in the available references. Dräger encourages responsible reporting of potential vulnerabilities [1].
