Unauthenticated remote code execution in Hyland PACSgear PACS Scan 5.2.1 lets remote attackers gain SYSTEM-level control of medical imaging servers by abusing an exposed .NET Remoting TCP service (PGImageExchQueue.exe) on port 22222. The exposed service grants arbitrary file read/write with no authentication, which is chained with a DLL hijack in the PGImageExchangeQueueSvc.exe service to run code as NT AUTHORITY\SYSTEM. Publicly available exploit code exists (published by VulnCheck); there is no public exploit identified as actively exploited, as it is not listed in CISA KEV.
