CVE-2025-60002 is a Cross-site Scripting (XSS) vulnerability classified under CWE-79 found in Juniper Networks Junos Space, a network management platform widely used for managing Juniper network devices. The vulnerability arises from improper neutralization of input during web page generation on the Template Definitions page, allowing an attacker to inject malicious script tags. When another user, potentially with administrative privileges, visits the compromised page, the injected scripts execute in the context of the victim’s session. This can lead to unauthorized command execution with the victim’s permissions, enabling actions such as session hijacking, data theft, or manipulation of network management operations. The vulnerability affects all versions of Junos Space prior to 24.1R4, with no patches currently linked, and no known exploits reported in the wild as of the publication date. The CVSS v3.1 score of 6.1 indicates a medium severity, with an attack vector over the network, low complexity, no privileges required, but requiring user interaction and resulting in limited confidentiality and integrity impacts. The vulnerability’s scope is confined to the Junos Space management interface, meaning exploitation affects the management plane rather than the underlying network devices directly. However, given the critical role of Junos Space in network operations, successful exploitation could indirectly impact network security and availability if administrative controls are compromised.

For European organizations, the impact of CVE-2025-60002 can be significant due to Junos Space’s role in centralized network management. Successful exploitation could allow attackers to execute scripts with the privileges of network administrators, potentially leading to unauthorized access to network configurations, theft of sensitive operational data, or manipulation of network device management. This could disrupt network operations, degrade service availability, or facilitate further attacks within the network environment. Confidentiality and integrity of network management data are primarily at risk, while availability impact is limited but possible if administrative controls are compromised. Organizations in sectors with critical infrastructure, such as telecommunications, finance, and government, are particularly vulnerable due to their reliance on Junos Space for managing large-scale network environments. The requirement for user interaction reduces the likelihood of automated widespread exploitation but does not eliminate risk, especially in environments where users frequently access the Template Definitions page or where social engineering could be used to lure administrators to malicious content.

1. Apply patches or updates from Juniper Networks as soon as version 24.1R4 or later becomes available to remediate the vulnerability. 2. Until patches are available, restrict access to the Junos Space management interface to trusted administrators only, using network segmentation and strong access controls. 3. Implement strict input validation and sanitization on all user-supplied data fields, especially those related to Template Definitions, to prevent script injection. 4. Educate administrators and users about the risks of clicking on untrusted links or visiting unverified pages within the management interface. 5. Monitor Junos Space logs and network traffic for unusual activity that could indicate attempted exploitation. 6. Employ Content Security Policy (CSP) headers and other web security mechanisms to limit the execution of injected scripts. 7. Use multi-factor authentication (MFA) for accessing Junos Space to reduce the risk of compromised credentials being exploited. 8. Regularly audit user permissions and remove unnecessary administrative privileges to minimize the impact of a successful attack.
