CVE-2026-58126 Details
Description
PACSgear PACS Scan 5.2.1 contains an unauthenticated remote code execution vulnerability that allows remote attackers to read and write arbitrary files by exploiting an exposed .NET Remoting TCP service on port 22222 via PGImageExchQueue.exe without any authentication requirement. Attackers can chain the arbitrary file write primitive with DLL hijacking in PGImageExchangeQueueSvc.exe, which loads missing DLLs such as CRYPTSP.DLL from the application directory, to achieve remote code execution as NT Authority\SYSTEM upon service restart.
A remote code execution vulnerability has been identified in PACSgear PACS Scan version 5.2.1. This vulnerability allows remote attackers to read and write arbitrary files by exploiting an exposed .NET Remoting TCP service on port 22222, through the executable PGImageExchQueue.exe, without any authentication. Attackers can combine the arbitrary file write capability with DLL hijacking in the PGImageExchangeQueueSvc.exe service, which runs as NT Authority\SYSTEM and loads missing DLLs like CRYPTSP.DLL from the application directory. This exploitation leads to remote code execution as NT Authority\SYSTEM when the service is restarted.
