Velociraptor NETWORK ACL bypass via upload_azure / upload_sftp / upload_smb VQL plugins

AI Analysis

No AI analysis yet.

Description

Missing authorization check in the upload_azure, upload_sftp, and upload_smb VQL plugins allows an authenticated analyst-role user can initiate attacker-controlled outbound network connections from the Velociraptor server, bypassing the NETWORK ACL permission boundary. This enables internal network reconnaissance via port oracle and potential data exfiltration to external endpoints.
