CVE-2023-39266Public exploitNetwork attack vector

Script execution via unsanitized logged username

Published Aug 29, 2023 · Updated Sep 27, 2024

Stored XSS in the web interface of Hewlett Packard Enterprise ArubaOS-Switch allows remote attackers to run script in an administrator's browser. The switch stores an unauthenticated, attacker-supplied username without sanitization and later renders that log value in the management interface. Exploitation requires WebAgent access and a user to view the poisoned log; affected configurations lack the operator-password and HTTPS protections identified by HPE.
