CVE-2025-67568 identifies a Missing Authorization vulnerability in the xtemos Basel product, specifically affecting versions up to and including 5.9.1. This vulnerability arises from incorrectly configured access control security levels, which allow unauthorized remote attackers to perform actions that should be restricted. The vulnerability does not require any authentication or user interaction, making it remotely exploitable with low attack complexity. According to the CVSS v3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N), the attack vector is network-based, no privileges or user interaction are needed, and the impact is limited to integrity, with no confidentiality or availability impact. The flaw could allow attackers to modify data or system states that should be protected by authorization checks, potentially leading to unauthorized changes within the application or its data. No known exploits have been reported in the wild, and no patches or mitigation links are currently provided by the vendor. The vulnerability was published on December 9, 2025, and assigned by Patchstack. Given the nature of the vulnerability, it is critical for organizations using xtemos Basel to audit their access control configurations to ensure proper authorization enforcement and to monitor for any suspicious activity that could indicate exploitation attempts.

For European organizations, the primary impact of CVE-2025-67568 is the potential for unauthorized modification of data or application state within xtemos Basel deployments. This could lead to data integrity issues, unauthorized changes to business logic or configurations, and potential downstream effects on business operations relying on the affected systems. Since confidentiality and availability are not impacted, the risk is more about trustworthiness and correctness of data rather than data leakage or service disruption. Organizations in sectors such as e-commerce, web development, and digital services that utilize xtemos Basel could face reputational damage or operational challenges if attackers exploit this vulnerability to alter critical data or configurations. The lack of authentication requirement increases the risk of exploitation by external attackers. However, the absence of known exploits in the wild and the medium CVSS score suggest that the threat is moderate but should not be ignored. European entities must prioritize identifying affected versions and implementing access control hardening to prevent unauthorized access.

1. Immediately audit all xtemos Basel installations to identify affected versions (<= 5.9.1). 2. Review and tighten access control configurations within the application to ensure that all sensitive operations require proper authorization checks. 3. Implement network-level controls such as firewalls or web application firewalls (WAFs) to restrict access to the Basel management interfaces to trusted IPs or VPNs. 4. Monitor application logs and network traffic for unusual or unauthorized access attempts targeting Basel components. 5. Engage with the vendor xtemos for official patches or updates addressing this vulnerability and apply them promptly once available. 6. Conduct internal penetration testing focusing on access control weaknesses in Basel deployments. 7. Educate system administrators and developers about secure configuration practices to prevent similar authorization issues. 8. Consider implementing multi-factor authentication (MFA) for administrative access to reduce risk even if authorization controls are bypassed. 9. Maintain an incident response plan tailored to integrity breaches to quickly respond if exploitation is detected.
