CVE-2025-56746 identifies a session fixation vulnerability in Creativeitem Academy LMS versions up to and including 5.13. The core issue is that the LMS does not regenerate session identifiers upon successful user authentication. Session fixation attacks exploit this by allowing an attacker to set or predict a session ID before the victim logs in. Once the victim authenticates, the attacker can use the predetermined session ID to hijack the authenticated session, gaining unauthorized access to the victim’s account and potentially sensitive information. This vulnerability undermines session management best practices, which mandate session ID regeneration to prevent fixation. Although no known exploits are currently reported in the wild, the vulnerability is straightforward to exploit since it does not require user interaction or complex attack vectors. The lack of a CVSS score necessitates a severity assessment based on the vulnerability’s characteristics. The vulnerability primarily impacts confidentiality and integrity by enabling unauthorized session takeover, which can lead to data exposure or manipulation. The affected LMS is widely used in educational and corporate training environments, making the impact significant for organizations relying on it for secure user authentication and data protection. The absence of patch links suggests that remediation may require vendor engagement or configuration changes. Organizations should prioritize implementing session ID regeneration immediately after login and review session management policies to mitigate this risk.

For European organizations, especially those in education, corporate training, and e-learning sectors using Creativeitem Academy LMS, this vulnerability poses a significant risk of unauthorized access to user accounts and sensitive data. Attackers exploiting session fixation can impersonate legitimate users, potentially accessing confidential educational records, personal information, and administrative functions. This can lead to data breaches, loss of user trust, regulatory non-compliance (e.g., GDPR violations), and operational disruptions. The impact extends beyond individual users to organizational reputation and legal liabilities. Since the LMS is often integrated with other systems, session hijacking could facilitate lateral movement within networks. The ease of exploitation without user interaction increases the threat level, making it critical for European entities to address this vulnerability promptly. Additionally, the lack of known exploits does not reduce urgency, as the vulnerability is straightforward to weaponize once discovered by attackers.

1. Immediately implement session ID regeneration upon successful user authentication within the LMS to prevent session fixation. 2. Apply any available patches or updates from Creativeitem as soon as they are released; if none are available, engage with the vendor for remediation timelines. 3. Conduct a thorough review of session management configurations and enforce secure cookie attributes such as HttpOnly, Secure, and SameSite. 4. Monitor session activity logs for anomalies indicative of session hijacking attempts, such as multiple logins from different IP addresses using the same session ID. 5. Educate users and administrators about the risks of session fixation and encourage practices such as logging out after sessions and avoiding shared devices. 6. Consider implementing multi-factor authentication (MFA) to reduce the impact of session hijacking. 7. Isolate and segment LMS infrastructure to limit potential lateral movement if a session is compromised. 8. Regularly audit and test the LMS environment for session management vulnerabilities using penetration testing or automated scanning tools.
