CVE-2025-59978Network attack vector

Authenticated command execution via stored script tags

Published Oct 9, 2025 · Updated Oct 9, 2025

Stored cross-site scripting in Juniper Networks Junos Space before 24.1R4 allows remote authenticated users to execute commands as an administrator. The web application stores attacker-supplied script tags directly in generated pages and executes them when another user views an affected page. A valid account and interaction by a second user are required; execution inherits that viewer's administrative permissions.
