CVE-2020-2012Network attack vector

Arbitrary file read via XML external entities

Published May 13, 2020 · Updated Sep 17, 2024

XXE in Palo Alto Networks PAN-OS for Panorama allows remote attackers to read arbitrary files through the management interface. The service parses attacker-controlled XML while external-entity resolution is enabled, allowing a declared file entity to dereference local paths. Network access to the Panorama management interface is the only reported gate; successful exploitation exposes file contents without changing data or interrupting service.
