After a scan, the Engine would follow the links and remove the files

Dell SupportAssist Client Consumer versions 3.9.13.0 and any versions prior to 3.9.13.0 contain an arbitrary file deletion vulnerability that can be exploited by using the Windows feature of NTFS called Symbolic links. Symbolic links can be created by any(non-privileged) user under some object directories, but by themselves are not sufficient to successfully escalate privileges. However, combining them with a different object, such as the NTFS junction point allows for the exploitation. Support assist clean files functionality do not distinguish junction points from the physical folder and proceeds to clean the target of the junction that allows nonprivileged users to create junction points and delete arbitrary files on the system which can be accessed only by the admin.
