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.
