CVE-2025-53236 is a missing authorization vulnerability found in AndonDesign's UDesign Core product, affecting all versions up to and including 4.14.0. The flaw arises from incorrectly configured access control security levels, which allow an attacker with some level of privileges (PR:L - privileges required) to bypass authorization checks. This means that users who should have limited access can perform unauthorized actions, potentially leading to unauthorized data access, modification, or disruption of service. The vulnerability is remotely exploitable over the network (AV:N) without requiring user interaction (UI:N), which increases its risk profile. The CVSS v3.1 base score is 6.3, indicating a medium severity level, with impacts on confidentiality, integrity, and availability rated as low to medium. The attack complexity is low (AC:L), meaning the exploit does not require sophisticated conditions. Although no known exploits are reported in the wild, the vulnerability poses a significant risk to organizations relying on UDesign Core for critical design and operational workflows. The lack of available patches at the time of publication necessitates immediate mitigation through configuration reviews and access control audits. This vulnerability underscores the criticality of proper authorization enforcement in software components that manage design and core operational data.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive design data, unauthorized modifications, or disruption of design workflows, potentially impacting product development and operational continuity. Confidentiality breaches could expose intellectual property or sensitive project information, while integrity violations could result in corrupted or maliciously altered design files. Availability impacts, though rated low, could disrupt services dependent on UDesign Core, affecting business operations. Organizations in sectors such as manufacturing, engineering, and infrastructure development that rely heavily on design software are particularly at risk. The medium severity rating suggests a moderate but tangible risk that could escalate if combined with other vulnerabilities or insider threats. Given the remote exploitability and lack of user interaction required, attackers could leverage compromised credentials or insider access to escalate privileges and cause damage. This could also have regulatory implications under GDPR if personal or sensitive data is involved in the design processes. Therefore, the threat is significant for European entities with critical design and operational dependencies on AndonDesign UDesign Core.

Until an official patch is released, European organizations should conduct immediate audits of user privileges and access control configurations within UDesign Core to ensure the principle of least privilege is strictly enforced. Restrict access to the UDesign Core system to trusted users only and monitor for unusual access patterns or privilege escalations. Implement network segmentation and firewall rules to limit exposure of UDesign Core services to only necessary internal or VPN-based connections. Employ multi-factor authentication (MFA) for all accounts with elevated privileges to reduce the risk of credential compromise. Regularly review and update user roles and permissions to prevent privilege creep. Maintain comprehensive logging and monitoring to detect unauthorized access attempts promptly. Once patches become available, prioritize their deployment in all affected environments. Additionally, conduct security awareness training focused on the risks of privilege misuse and the importance of access control hygiene.
