Lantronix Device installer is vulnerable to XML external entity (XXE) attacks in configuration files read from the network device. An attacker could obtain credentials, access these network devices, and modify their configurations. An attacker may also gain access to the host running the Device Installer software or the password hash of the user running the application.
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.
