Description

Mirasys VMS before V7.6.1 and 8.x before V8.3.2 mishandles the Mirasys.Common.Utils.Security.DataCrypt method in Common.dll in AuditTrailService in SMServer.exe. This method triggers insecure deserialization within the .NET garbage collector, in which a gadget (contained in a serialized object) may be executed with SYSTEM privileges. The attacker must properly encrypt the object; however, the hardcoded keys are available.

Affected products

Mirasys Vms: before 7.6.1; from 8.0.0 before 8.3.2 — fixed in 7.6.1, 8.3.2

How to fix

Upgrade to a fixed version: Mirasys Vms 7.6.1, 8.3.2. Check the vendor advisory for mitigations.
