Description

This security bulletin contains information about 1 vulnerability.


1) Improper access control (CVE-ID: N/A)

CWE-ID: CWE-284 - Improper Access Control

The vulnerability allows a remote user to disclose sensitive information.

The vulnerability exists due to improper access control in the public share creation and resolution logic when creating a public share for a nonexistent path. A remote user can create a public share for a path before a file exists there to disclose sensitive information.

The share is bound only to a path string and becomes valid later if a file is subsequently created at that path.
