CVE-2025-59987Network attack vector

Victim-session command execution via search-field script injection

Published Oct 9, 2025 · Updated Oct 9, 2025

Reflected XSS in Juniper Networks Junos Space before 24.1R4 allows remote attackers to execute commands under a visiting user's permissions. The arbitrary device search field accepts injected script tags and returns them in page content without neutralizing executable markup. Exploitation requires another user to visit the crafted search result; the script then acts in that user's session, including an administrator session.
