SLD Registration in SAP HANA (fixed in versions 1.0, 2.0) does not sufficiently validate an XML document accepted from an untrusted source. The attacker can call SLDREG with an XML file containing a reference to an XML External Entity (XXE). This can cause SLDREG to, for example, continuously loop, read arbitrary files and even send local files.

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.
