CVE-2025-69275 identifies a vulnerability in Broadcom DX NetOps Spectrum, a widely used network monitoring and management platform, specifically in versions 24.3.9 and earlier. The root cause is a dependency on a vulnerable third-party component that introduces a DOM-Based Cross-Site Scripting (XSS) flaw. DOM-Based XSS occurs when client-side scripts write untrusted data to the Document Object Model without proper sanitization, enabling attackers to inject and execute malicious scripts within the victim's browser context. This vulnerability affects both Windows and Linux deployments of DX NetOps Spectrum. The CVSS 4.0 vector indicates the attack vector is network-based (AV:N), with high attack complexity (AC:H), no privileges required (PR:L), and no user interaction needed (UI:N). The vulnerability impacts confidentiality and integrity highly (VC:H, VI:L), with no impact on availability (VA:N). The scope is high (SC:H), meaning the vulnerability affects components beyond the initially vulnerable component, and the impact is limited (SI:L). No patches are currently linked, and no known exploits exist in the wild, but the presence of a vulnerable third-party dependency suggests potential for exploitation once weaponized. The CWE-1395 classification highlights the risk of relying on vulnerable external components, emphasizing the need for supply chain security and dependency management. This vulnerability could allow attackers to execute arbitrary scripts, potentially leading to session hijacking, data theft, or further compromise of the network management environment.

For European organizations, the impact of this vulnerability could be significant, especially for those relying on Broadcom DX NetOps Spectrum for critical network operations and infrastructure monitoring. Exploitation could lead to unauthorized script execution within the application context, risking exposure of sensitive network data, credentials, or configuration details. This could facilitate lateral movement within the network or enable attackers to manipulate monitoring data, undermining network integrity and operational reliability. Given the high complexity but low privilege requirements, attackers with limited access could exploit this vulnerability remotely, increasing the attack surface. The potential compromise of network management tools is particularly concerning for sectors such as telecommunications, finance, energy, and government agencies, which are prevalent across Europe. Disruption or manipulation of network monitoring could delay detection of other attacks or cause misinformed operational decisions, amplifying the threat to availability indirectly. The absence of known exploits currently provides a window for mitigation, but the dependency on third-party components underscores ongoing supply chain risks.

European organizations should immediately conduct an inventory of DX NetOps Spectrum deployments and verify versions to identify affected systems. Although no official patches are currently linked, organizations should monitor Broadcom’s advisories closely and apply updates as soon as they become available. In the interim, implement strict Content Security Policies (CSP) to restrict the execution of untrusted scripts within the application context. Review and harden input validation and sanitization mechanisms in any custom integrations or extensions interacting with DX NetOps Spectrum. Employ network segmentation and access controls to limit exposure of the management platform to trusted users and networks only. Conduct regular dependency audits to identify and remediate vulnerable third-party components proactively. Additionally, enhance monitoring for anomalous activities indicative of XSS exploitation attempts, such as unusual script injections or unexpected browser behaviors. Consider deploying Web Application Firewalls (WAFs) with rules targeting DOM-Based XSS patterns. Finally, educate administrators and users about the risks of XSS and safe browsing practices within the network operations environment.
