CVE-2021-4479 | BDVDB-2026-337162 Detail

DrägerAtlan A350

Description#

Dräger Atlan A350 versions 1.00 up to and including 1.01 contains an improper input handling vulnerability that allows attackers to cause a denial of service by sending specifically crafted non-Medibus-compliant data through the Medibus interface. Attackers can transmit malformed data to overload the internal processor, gradually disrupting device operation over several hours and causing loss of data transmission, delayed display of real-time curves, and deviation between displayed airway pressure values and screen curves.

Impact#

Per CVSS v3.1: confidentiality impact none, integrity impact none, availability impact low. Attack vector: network.

Weaknesses#
