Description TEJ RATHI 2023-07-11 05:28:16 UTC 
CVE-2023-33127 - The Windows .NET runtime exposes an IPC diagnostic endpoint named pipe for collecting diagnostic information and debugging. DCOM applications that expose a diagnostic port can be abused to achieve cross-session elevation of privilege (EoP) and code execution by taking control of the diagnostic port.
