First published: Thu Apr 22 2021(Updated: )

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Oracle OSS Support Tools. Authentication is required to exploit this vulnerability. The specific flaw exists within the Diagnostic Assistant component.
