Session hijacking via precreated RDP named pipes
Published Apr 15, 2022 · Updated Jan 2, 2025
Remote Desktop Protocol flaws in affected Microsoft Windows releases allow remote authenticated users to execute code in another RDP session. The rdpcorets.dll pipe manager connects to a first-created TSVCPIPE server without verifying its process owner, letting an attacker precreate the pipe and control later instances. Exploitation requires a low-privileged RDP account and a victim who disconnects and reconnects; successful attacks expose or alter virtual-channel data and redirected devices.
