CVE-2025-4555 is a critical vulnerability identified in the Okcat Parking Management Platform developed by ZONG YU. The vulnerability is classified under CWE-306, which corresponds to Missing Authentication for Critical Function. Specifically, the web management interface of the platform lacks proper authentication controls, allowing unauthenticated remote attackers to directly access sensitive system functions. These functions include opening parking gates, viewing license plate information and parking records, and restarting the system. The absence of authentication means that any attacker with network access to the management interface can perform these actions without credentials or user interaction. The CVSS v3.1 base score of 9.8 reflects the high severity, with metrics indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). This vulnerability exposes critical operational controls and sensitive data, potentially allowing attackers to manipulate physical access controls, disrupt parking operations, and compromise privacy by accessing vehicle and user data. No patches or mitigations have been published at the time of disclosure, and there are no known exploits in the wild yet. However, the ease of exploitation and the critical nature of the functions affected make this a highly urgent security issue for any organization using the Okcat platform.

For European organizations, the impact of this vulnerability can be severe, especially for entities relying on the Okcat Parking Management Platform for controlling physical access to parking facilities. Unauthorized gate opening can lead to physical security breaches, unauthorized vehicle entry, and potential theft or vandalism. Access to license plate and parking records compromises personal data privacy, potentially violating GDPR requirements and exposing organizations to regulatory penalties. Restarting the system remotely can cause denial of service, disrupting parking operations and affecting business continuity. Organizations such as commercial real estate managers, municipal parking authorities, hospitals, airports, and large corporate campuses using this platform are at risk. The vulnerability could also be leveraged as a foothold for further network intrusion if the parking management system is connected to broader enterprise networks. The critical nature of the vulnerability and the lack of authentication controls elevate the risk of both insider and external attackers exploiting the system, potentially causing operational, financial, and reputational damage.

Given the absence of an official patch, European organizations should immediately implement network-level access controls to restrict access to the Okcat Parking Management Platform management interface. This includes isolating the management interface on a dedicated VLAN or subnet with strict firewall rules permitting access only from trusted administrative hosts. Employ VPNs or zero-trust network access solutions to enforce strong authentication before allowing any connectivity to the management interface. Conduct thorough network scans to identify all instances of the Okcat platform and verify exposure to the internet or untrusted networks. Monitor logs and network traffic for unusual activity targeting the management interface. Where possible, disable remote management features until a patch is available. Engage with the vendor for timelines on patch releases and request interim mitigations or configuration changes. Additionally, implement physical security controls to mitigate risks from unauthorized gate openings and review incident response plans to address potential exploitation scenarios. Finally, ensure that data privacy compliance measures are reviewed and updated to account for the risk of unauthorized data access.
