Microsoft · Messaging Queuing Service · CVE-2023-31222
**Name of the Vulnerable Software and Affected Versions**
Medtronic's Paceart Optima versions 1.11 and earlier
**Description**
The issue is related to the deserialization of untrusted data in the Microsoft Messaging Queuing Service of Medtronic's Paceart Optima system. This allows an unauthorized user to impact the system, potentially causing data to be deleted, stolen, or modified, or using the system for further network penetration via network connectivity. The vulnerability can be exploited by sending specially crafted messages, allowing a remote attacker to gain unauthorized access to read, modify, or delete data, execute arbitrary code, or cause a denial of service.
**Recommendations**
For Medtronic's Paceart Optima versions 1.11 and earlier, consider disabling the deserialization of untrusted data in the Microsoft Messaging Queuing Service as a temporary workaround until a patch is available. Restrict access to the Paceart Optima system to minimize the risk of exploitation. Avoid using the system for further network connectivity until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
