CVE-2025-52614 identifies a vulnerability in the HCL Unica Platform, a marketing and customer engagement software suite, where cookies used in HTTPS sessions do not have the 'Secure' attribute set. The 'Secure' attribute instructs browsers to send cookies only over encrypted HTTPS connections, preventing exposure over unencrypted HTTP. Without this attribute, cookies may be transmitted in plaintext if a user accesses the site via HTTP, enabling attackers on the same network or performing man-in-the-middle attacks to intercept session cookies. This vulnerability is classified under CWE-614, which concerns sensitive cookies in HTTPS sessions lacking the 'Secure' flag. The CVSS 3.1 base score is 3.5 (low), reflecting that exploitation requires network access, low attack complexity, privileges, and user interaction, but results in limited confidentiality impact without affecting integrity or availability. The vulnerability affects Unica Platform versions up to 25.1. No public exploits are known, and no patches have been linked yet, indicating this is a recently disclosed issue. Attackers could exploit this by tricking users into clicking crafted links or visiting malicious websites, potentially leading to session hijacking or unauthorized access to user sessions. The vulnerability primarily threatens confidentiality by exposing session tokens, which could lead to unauthorized actions if combined with other weaknesses. However, the requirement for user interaction and privileges reduces the likelihood of widespread exploitation.

For European organizations, the vulnerability poses a risk of session cookie interception, potentially leading to unauthorized access to user sessions within the Unica Platform. This could compromise sensitive marketing data, customer profiles, and campaign management information, impacting confidentiality. Organizations handling personal data under GDPR must consider the risk of data leakage and potential regulatory consequences. Although the vulnerability does not directly affect system integrity or availability, unauthorized session access could enable attackers to manipulate marketing campaigns or extract sensitive information. The impact is more pronounced in sectors heavily reliant on customer engagement platforms, such as retail, finance, and telecommunications. Given the low CVSS score and absence of known exploits, the immediate risk is moderate; however, the potential for targeted attacks in high-value environments exists. European entities with extensive use of HCL Unica should assess their exposure and prioritize mitigation to prevent lateral movement or escalation from this vulnerability.

To mitigate CVE-2025-52614, organizations should first verify if they are running affected versions (<= 25.1) of HCL Unica Platform. Although no official patches are currently linked, administrators should configure the platform or underlying web servers to enforce the 'Secure' attribute on all session cookies. This can often be done via application configuration or web server settings (e.g., modifying cookie flags in HTTP response headers). Additionally, enforce strict HTTPS usage by redirecting all HTTP traffic to HTTPS and implementing HTTP Strict Transport Security (HSTS) headers to prevent downgrade attacks. Conduct user awareness training to reduce the risk of users clicking malicious links that could trigger exploitation. Monitor network traffic for unencrypted cookie transmissions and suspicious activities. Regularly review and update session management policies to ensure cookies have both 'Secure' and 'HttpOnly' flags set. Finally, stay alert for official patches or updates from HCL Software and apply them promptly once available.
