CVE-2025-10228 is a session fixation vulnerability categorized under CWE-384, discovered in Rolantis Information Technologies' Agentis product prior to version 4.44. Session fixation occurs when an attacker can set or fix a user's session identifier before authentication, allowing the attacker to hijack the session once the user logs in. This vulnerability enables an attacker to craft a URL or other means to force a victim to use a known session ID. After the victim authenticates, the attacker can use the fixed session ID to gain unauthorized access with the victim's privileges. The CVSS 3.1 base score of 8.8 reflects high impact on confidentiality, integrity, and availability, with network attack vector, low complexity, no privileges required, but user interaction needed. The vulnerability affects all versions before 4.44, with no patches currently linked but presumably forthcoming. No known exploits have been reported in the wild yet, but the nature of session fixation makes it a critical risk for web applications relying on Agentis for session management. The vulnerability can lead to full account takeover, data theft, unauthorized actions, and potential disruption of services. Detection may be challenging without proper monitoring of session anomalies. This issue highlights the importance of secure session management practices, including regenerating session IDs after login and validating session tokens properly.

For European organizations using Rolantis Agentis, this vulnerability poses a significant risk of session hijacking, potentially leading to unauthorized access to sensitive data, manipulation of critical processes, and service disruption. Sectors such as finance, healthcare, government, and critical infrastructure that rely on Agentis for operational or security functions may face confidentiality breaches, data integrity violations, and availability issues. Attackers exploiting this flaw could impersonate legitimate users, escalate privileges, or conduct fraudulent transactions. The impact is exacerbated by the network-exploitable nature and low attack complexity, increasing the likelihood of targeted attacks or automated exploitation once public exploits emerge. Organizations may also face regulatory and compliance consequences under GDPR if personal data is compromised. The absence of known exploits currently provides a window for proactive mitigation, but the high severity score demands immediate attention to prevent potential widespread exploitation.

1. Upgrade Agentis to version 4.44 or later as soon as the patch is released by Rolantis Information Technologies. 2. In the interim, implement strict session management controls such as regenerating session IDs immediately after user authentication to prevent fixation. 3. Enforce secure cookie attributes (HttpOnly, Secure, SameSite) to reduce session token theft risks. 4. Monitor web server and application logs for unusual session activity, such as multiple logins from the same session ID or unexpected session reuse. 5. Educate users to avoid clicking suspicious links that could contain fixed session IDs. 6. Employ web application firewalls (WAFs) with rules to detect and block session fixation attempts. 7. Conduct regular security assessments and penetration testing focusing on session management weaknesses. 8. Review and harden authentication workflows to ensure session tokens are validated and invalidated appropriately. 9. Coordinate with Rolantis support for timely updates and advisories. 10. Prepare incident response plans to quickly address any detected session hijacking attempts.
