Keyoti SearchUnit prior to 9.0.0. is vulnerable to XML External Entity (XXE). An attacker who can force a vulnerable SearchUnit host into parsing maliciously crafted XML and/or DTD files can exfiltrate some files from the underlying operating system.
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.
