Deserialization of untrusted data in Microsoft Messaging Queuing Service in Medtronic's Paceart Optima versions 1.11 and earlier on Windows allows an unauthorized user to impact a healthcare delivery organization’s Paceart Optima system cardiac device causing data to be deleted, stolen, or modified, or the Paceart Optima system being used for further network penetration via network connectivity.

Deserialization of untrusted data in Microsoft Messaging Queuing Service in Medtronic's Paceart Optima versions 1.11 and earlier on Windows allows an unauthorized user to impact a healthcare delivery organization’s Paceart Optima system cardiac device causing data to be deleted, stolen, or modified, or the Paceart Optima system being used for further network penetration via network connectivity.

If a healthcare delivery organization has enabled the optional Paceart Messaging Service in the Paceart Optima system, an unauthorized user could exploit this vulnerability to perform remote code execution and/or denial-of-service (DoS) attacks by sending specially crafted messages to the Paceart Optima system. Remote code execution could result in the deletion, theft, or modification of Paceart Optima system's cardiac device data, or use of the Paceart Optima system for further network penetration. A DoS attack could cause the Paceart Optima system to slow or be unresponsive.
