Executive Summary

This vulnerability involves a session ID leak when saving a file downloaded from CGM CLININET. The session identifier is exposed because of a Windows security feature that stores extra metadata in an NTFS alternate data stream (ADS) for files downloaded from potentially untrusted sources. This exposure can allow attackers to access session information unintentionally leaked through these metadata streams.

Impact Analysis

The vulnerability can lead to unauthorized disclosure of session IDs, which may allow attackers to hijack user sessions or gain unauthorized access to the system. This could result in compromised user accounts, including potentially privileged sessions, leading to data breaches or unauthorized actions within the affected software environment.
