CVE-2020-2017Network attack vector

Administrative actions via management-interface DOM injection

Published May 13, 2020 · Updated Sep 16, 2024

DOM-based XSS in Palo Alto Networks PAN-OS management interfaces allows remote attackers to execute JavaScript in an administrator's browser. The vendor has not disclosed the affected client-side source, DOM sink, or exact operation that incorporates crafted-link data. Exploitation requires an authenticated administrator to open the crafted link, after which the script can perform administrative actions through that session.
