## Overview

Exterro FTK Imager before 8.3 contains an XML external entity (XXE) injection vulnerability that allows attackers to read arbitrary files from the host filesystem by embedding malicious external entity references and attacker-controlled XSLT stylesheets within a Report.xml file inside a UFDR ZIP evidence item. Attackers can craft a malicious UFDR archive that, when previewed by an examiner, causes the XML parser to resolve file:// external entity references and execute msxsl:script within the external stylesheet to exfiltrate the resolved file contents to an attacker-controlled endpoint via a generated image URL.
