FAQ

What privileges could be gained by an attacker who successfully exploited the vulnerability? An attacker who successfully exploited this vulnerability could gain specific limited SYSTEM privileges. According to the CVSS metrics, successful exploitation of this vulnerability could lead to no loss of confidentiality (C:N) but have major impact on integrity (I:H) and on availability (A:H). What does that mean for this vulnerability? This vulnerability does not allow disclosure of any confidential information, but could allow an attacker to delete data that could include data that results in the service being unavailable. How could an attacker exploit this vulnerability? This vulnerability could allow a standard domain user to delete arbitrary files and folders with system privileges. This could be achieved when "Folder preference - delete" is configured and the user has write access, allowing them to set a reparse point.
