An improper restriction of XML external entity reference vulnerability in the parser of XML responses of FortiPortal before 6.0.6 may allow an attacker who controls the producer of XML reports consumed by FortiPortal to trigger a denial of service or read arbitrary files from the underlying file system by means of specifically crafted XML documents.

Weakness

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.
