XML external entity injection(XXE) is a vulnerability that allows an attacker to interfere with an application's processing of XML data. This attack occurs when XML input containing a reference to an external entity is processed by a weakly configured XML parser. The software 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. Here, XML external entity injection lead to External Service interaction & Internal file read in Business Central and also Kie-Server APIs.
The product does not properly neutralize special elements that are used in XML, allowing attackers to modify the syntax, content, or commands of the XML before it is processed by an end system.
