Victim-session script execution via unsanitized Model Devices input
Published Oct 9, 2025 · Updated Oct 9, 2025
Cross-site scripting in Juniper Networks Junos Space before 24.1R4 allows remote attackers to run script in another user’s browser. Model Devices input fields accept injected script tags and return the unsanitized content when another user visits the affected view. No authentication is required to submit the input, but execution requires a victim to visit the content; the script acts with that user’s permissions, including administrator permissions.
