KYOCERA Net Admin 3.4.0906 contains an XML External Entity (XXE) injection vulnerability in the Multi-Set Template Editor that allows unauthenticated attackers to read arbitrary system files. Attackers can craft a malicious XML file with external entity references to retrieve sensitive configuration data like database credentials through an out-of-band channel attack.
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.
