An issue was discovered in Ahsay Cloud Backup Suite before 8.1.1.50. With a valid administrator account, the Move / Import / Export Users screen has an Import Users option. This option accepts a ZIP archive containing a users.xml file that can trigger XXE.
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
