CVE-2025-69327 is a vulnerability identified in magepeopleteam's Car Rental Manager software versions up to 1.0.9, characterized by missing authorization controls. This means that certain functions or endpoints within the application do not properly verify whether a user has the necessary permissions before allowing actions to be performed. As a result, users with limited privileges (PR:L) can exploit this flaw over the network (AV:N) without requiring any user interaction (UI:N) to perform unauthorized operations that affect data integrity (I:L). The vulnerability does not compromise confidentiality or availability, indicating that sensitive data is not exposed and system uptime is not impacted. The CVSS vector (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) highlights that the attack complexity is low (AC:L), and the scope remains unchanged (S:U). No patches or known exploits are currently available, suggesting that the vulnerability is newly disclosed and may not yet be actively exploited. The root cause is an incorrectly configured access control mechanism within the Car Rental Manager application, which is critical for ensuring that users can only perform actions they are authorized to do. This vulnerability could allow attackers to manipulate booking data, modify rental agreements, or alter other critical information managed by the software, potentially leading to operational disruptions or financial discrepancies.

For European organizations, especially those operating in the car rental sector using magepeopleteam's Car Rental Manager software, this vulnerability poses a risk of unauthorized data modification. While it does not expose sensitive customer information or cause service outages, the integrity of rental records and transactional data could be compromised. This could lead to incorrect billing, fraudulent rentals, or loss of trust from customers and partners. Additionally, unauthorized changes might complicate regulatory compliance, particularly with data accuracy requirements under GDPR. The impact is more pronounced for larger rental companies or those integrated with other enterprise systems, where data integrity is critical for business operations. Although no active exploitation is reported, the presence of this vulnerability increases the attack surface and could be leveraged in targeted attacks or insider threat scenarios.

Organizations should immediately review and strengthen access control policies within the Car Rental Manager application. This includes implementing role-based access control (RBAC) to ensure users can only access functions necessary for their roles. Conduct thorough code and configuration audits to identify and fix missing authorization checks. Until an official patch is released, consider deploying web application firewalls (WAFs) with custom rules to detect and block unauthorized requests targeting sensitive endpoints. Monitor application logs for unusual activity patterns indicative of privilege escalation attempts. Engage with the vendor for timely updates and patches. Additionally, restrict network access to the application to trusted IP ranges and enforce multi-factor authentication for administrative users to reduce the risk of credential misuse. Regularly back up critical data to enable recovery in case of unauthorized modifications.
