Mahara 1.4.x before 1.4.4 and 1.5.x before 1.5.3 allows remote attackers to read arbitrary files or create TCP connections via an XML external entity (XXE) injection attack, as demonstrated by reading config.php.

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.
