CVE-2025-69327 is a vulnerability identified in the magepeopleteam Car Rental Manager software, affecting versions up to and including 1.0.9. The core issue is a missing authorization control, meaning that the software fails to properly enforce access control policies on certain functions or endpoints. This misconfiguration allows users with limited privileges (PR:L) to perform unauthorized actions that should be restricted, potentially modifying data or configurations they should not have access to. The vulnerability is exploitable remotely over the network (AV:N) without requiring user interaction (UI:N), which increases its risk profile. However, the attack complexity is low (AC:L), and the scope remains unchanged (S:U), indicating that the exploit affects only the vulnerable component without extending to other system components. The CVSS base score is 4.3, reflecting a medium severity primarily due to the impact on integrity (I:L) but no impact on confidentiality or availability. No known exploits have been reported in the wild, and no patches have been released at the time of this analysis. The vulnerability arises from incorrectly configured access control security levels, a common security oversight that can lead to privilege escalation or unauthorized data manipulation. Organizations using this software for managing car rental operations are at risk of unauthorized changes that could disrupt business processes or lead to data integrity issues.

For European organizations, the missing authorization vulnerability could lead to unauthorized modifications of rental records, pricing, or customer data within the Car Rental Manager system. While confidentiality and availability are not directly impacted, integrity compromises can disrupt business operations, cause financial discrepancies, or damage customer trust. Attackers with low-level privileges could escalate their access or manipulate critical data, potentially leading to fraudulent transactions or operational errors. Given the nature of car rental services, such disruptions could affect service delivery, billing accuracy, and regulatory compliance. The impact is particularly relevant for large car rental companies or agencies relying heavily on this software for daily operations. Additionally, unauthorized changes could complicate audits and legal accountability under European data protection regulations such as GDPR if personal data integrity is compromised.

1. Immediately review and restrict user privileges within the Car Rental Manager system to the minimum necessary, ensuring no users have excessive permissions. 2. Implement network segmentation and firewall rules to limit access to the Car Rental Manager application only to trusted internal networks and authorized personnel. 3. Monitor logs and audit trails for unusual or unauthorized access attempts, focusing on privilege escalation or data modification activities. 4. Engage with the vendor (magepeopleteam) to obtain patches or updates addressing this vulnerability as soon as they become available. 5. Conduct a thorough security assessment of the Car Rental Manager deployment, including penetration testing to identify other potential access control weaknesses. 6. Educate system administrators and users about the risks of privilege misuse and enforce strong authentication and session management practices. 7. Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block unauthorized access attempts until patches are applied.
