7.3HIGH
What is CVE-2025-30038?
The vulnerability involves a session ID leak that occurs when users download files from CGM CLININET. This issue arises due to a built-in Windows feature that stores extra metadata in an NTFS alternate data stream (ADS) for files sourced from potentially untrusted locations. As a consequence, the session ID can inadvertently be exposed, leading to potential exploitation by malicious actors.
