CVE-2025-60001
📋 TL;DR
This Cross-Site Scripting (XSS) vulnerability in Juniper Networks Junos Space allows attackers to inject malicious scripts into the Generate Report page. When another user views the compromised page, the attacker can execute commands with that user's permissions, potentially including administrator privileges. All Junos Space versions before 24.1R4 are affected.

⚠️ Risk & Real-World Impact
Worst Case
An attacker could gain administrative access to Junos Space, allowing them to modify network configurations, create new users, exfiltrate sensitive network data, or deploy additional malicious payloads across the network infrastructure.
Likely Case
Attackers would typically steal session cookies or credentials to hijack user sessions, potentially gaining access to network management functions and sensitive configuration data.
If Mitigated
With proper network segmentation and access controls, the impact would be limited to the Junos Space management interface, preventing lateral movement to other network devices.
🎯 Exploit Status
Exploitation requires the attacker to have access to create or modify reports, then trick another user into viewing the malicious report. This typically requires some level of authenticated access.
