CVE-2025-12104 identifies a critical security vulnerability in Azure Access Technology's BLU-IC2 and BLU-IC4 products, specifically versions through 1.19.5. The root cause is the use of unmaintained and outdated third-party UI dependencies, which introduces exploitable weaknesses in the user interface layer. These dependencies may contain known security flaws that attackers can leverage remotely without requiring authentication or user interaction. The vulnerability impacts confidentiality, integrity, and availability with high severity across all affected systems, as indicated by the CVSS 4.0 score of 10.0 and vector metrics showing network attack vector, low attack complexity, no privileges or user interaction needed, and high impact on all security properties. The CWE-1104 classification highlights the risk of relying on unmaintained components, which often lack security updates and can harbor multiple vulnerabilities. Although no exploits have been observed in the wild yet, the critical nature and ease of exploitation make this a significant threat. The affected products are part of Azure Access Technology's portfolio, which is integrated into various enterprise environments, potentially exposing sensitive data and critical operations to compromise. The absence of available patches at the time of publication necessitates immediate risk mitigation through alternative controls and vendor engagement.

For European organizations, this vulnerability presents a severe risk due to the widespread adoption of Azure cloud services and related technologies in critical sectors such as finance, healthcare, government, and manufacturing. Exploitation could lead to unauthorized data access, data manipulation, service disruption, and potential lateral movement within networks. The high severity and ease of exploitation mean attackers can compromise systems remotely without needing credentials or user actions, increasing the likelihood of successful attacks. This could result in significant operational downtime, regulatory non-compliance (e.g., GDPR breaches), financial losses, and reputational damage. Organizations relying on BLU-IC2 and BLU-IC4 for access control or identity management are particularly vulnerable, as compromise here could undermine broader security postures and trust boundaries. The lack of patches further exacerbates the risk, making timely mitigation critical to prevent exploitation.

1. Immediately inventory all deployments of BLU-IC2 and BLU-IC4 within the organization to identify affected versions (up to 1.19.5). 2. Engage with Azure Access Technology vendors for updates or patches addressing the outdated UI dependencies; prioritize applying these as soon as they become available. 3. In the interim, implement network segmentation and strict access controls to isolate vulnerable systems from untrusted networks and limit exposure. 4. Employ Web Application Firewalls (WAFs) or Intrusion Prevention Systems (IPS) with custom rules to detect and block exploitation attempts targeting UI components. 5. Conduct thorough security assessments and penetration tests focusing on the UI layers to identify potential attack vectors. 6. Monitor network and application logs for unusual activity indicative of exploitation attempts. 7. Review and update third-party component management policies to prevent future use of unmaintained dependencies. 8. Educate development and operations teams on the risks of using outdated components and enforce secure software supply chain practices.
