Introduction
Malicious scripts injected into a security management platform can silently compromise administrator sessions and alter network-wide security policies. Juniper Networks Junos Space Security Director, a widely used platform for centralized management of Juniper security devices, was found vulnerable to stored cross-site scripting (CVE-2025-59974) in all versions before 24.1R4.
About Juniper Networks and Junos Space Security Director: Juniper Networks is a global leader in networking and security infrastructure, providing solutions to large enterprises, service providers, and government agencies. Junos Space Security Director is their flagship product for managing security policies, device configurations, and monitoring across extensive Juniper deployments. The platform's reach and administrative privileges make vulnerabilities here particularly impactful for organizations relying on Juniper for network defense.
Technical Information
CVE-2025-59974 is a stored cross-site scripting vulnerability classified under CWE-79 (Improper Neutralization of Input During Web Page Generation). The root cause is insufficient sanitization or encoding of user-supplied input within the Junos Space Security Director web interface. Attackers can inject JavaScript or other executable scripts into fields such as device template definitions or policy descriptions. These payloads are stored in backend databases and later rendered in the browsers of other authenticated users who access the affected pages.
The exploitation path involves:
- Attacker submits a malicious script through a vulnerable input field (e.g., policy name or description).
- The application stores this input without adequate filtering.
- When another user (often with higher privileges) views the affected page, the script executes in their browser context.
This can lead to session hijacking, credential theft, unauthorized changes to security configurations, and further compromise of the managed network infrastructure. The risk is heightened by the privileged nature of Security Director users and the platform's central role in network security operations.
Affected Systems and Versions
- Product: Junos Space Security Director
- Affected versions: All versions before 24.1R4
- Fixed in: 24.1R4
No configuration-specific exclusions are documented. All deployments running a version prior to 24.1R4 are vulnerable.
Vendor Security History
Junos Space Security Director has experienced multiple web application vulnerabilities over the years, including:
- Multiple XSS vulnerabilities (see 2025-10 Security Bulletin)
- Command injection vulnerabilities (e.g., CVE-2024-39563)
- Authorization and privilege management issues
Juniper typically issues coordinated advisories and releases patches promptly. However, the recurrence of web security flaws suggests ongoing challenges in secure coding and testing practices for their management platforms.
