CVE-2025-12031 identifies a security vulnerability categorized under CWE-1004, where sensitive cookies in Azure Access Technology's BLU-IC2 and BLU-IC4 products (up to version 1.19.5) are missing the 'HttpOnly' attribute. This attribute is critical because it prevents client-side scripts, such as JavaScript, from accessing cookie data, which often contains sensitive session identifiers or authentication tokens. Without 'HttpOnly', malicious scripts injected via cross-site scripting (XSS) or other client-side attack vectors can read these cookies, potentially leading to session hijacking or unauthorized access. The vulnerability also involves the absence of the 'Secure' flag, which ensures cookies are only transmitted over HTTPS, reducing the risk of interception. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). This suggests the vulnerability can be exploited remotely without user interaction but requires some level of privilege, likely meaning attacker access to a user session or network. No public exploits have been reported yet, but the vulnerability is published and should be addressed promptly. The affected products are part of Azure Access Technology's portfolio, which is used in various enterprise and cloud environments, making the vulnerability relevant for organizations relying on these technologies.

For European organizations, exploitation of this vulnerability could lead to unauthorized disclosure of sensitive session cookies, enabling attackers to impersonate legitimate users or escalate privileges within affected systems. This can compromise confidentiality and integrity of user sessions and potentially lead to broader network access or data breaches. Sectors such as finance, healthcare, and critical infrastructure, which often use Azure cloud services and related access technologies, are particularly at risk. The lack of 'HttpOnly' and 'Secure' flags increases exposure to client-side attacks, especially in environments where XSS vulnerabilities exist or where network traffic interception is possible. While the vulnerability does not directly affect system availability, the resulting breaches could cause operational disruptions, regulatory non-compliance, and reputational damage. The medium severity rating reflects the moderate impact and relatively straightforward exploitation path, emphasizing the need for timely remediation to protect sensitive data and maintain trust.

Organizations should immediately review and update cookie handling configurations in BLU-IC2 and BLU-IC4 products to ensure that all sensitive cookies are set with the 'HttpOnly' and 'Secure' flags. This prevents client-side scripts from accessing cookie data and ensures cookies are only transmitted over encrypted HTTPS connections. Conduct thorough code and configuration audits to identify any cookies lacking these attributes. Implement Content Security Policy (CSP) headers to mitigate the risk of XSS attacks that could exploit this vulnerability. Regularly update the affected Azure Access Technology products to the latest versions once patches become available. Employ web application firewalls (WAFs) to detect and block malicious scripts attempting to exploit cookie access. Additionally, monitor logs for unusual access patterns or session anomalies that could indicate exploitation attempts. Educate developers and administrators on secure cookie practices and the importance of HTTP security headers. Finally, integrate this vulnerability into vulnerability management and incident response processes to ensure ongoing vigilance.
