EnterpriseDB Hybrid Manager - LTS versions 1.2 and 1.3 contain a critical vulnerability identified as CVE-2025-14038, classified under CWE-862 (Missing Authorization). The vulnerability arises from a misconfiguration in the Istio Gateway, which is responsible for enforcing authentication and authorization policies on gRPC endpoints used by the Hybrid Manager service. Specifically, certain gRPC endpoints were omitted from the explicit permission definitions in the Istio Gateway configuration, resulting in these endpoints being accessible without any authentication or authorization checks. This allows unauthenticated attackers to directly interact with these endpoints, potentially reading sensitive data or causing denial-of-service conditions by submitting malformed data. The flaw affects all deployments using the specified versions and does not require any user interaction or privileges to exploit, making it accessible remotely over the network. The vulnerability has been assigned a CVSS v3.1 score of 7.0, indicating high severity due to its network attack vector, lack of required privileges, and significant impact on availability and limited impact on confidentiality and integrity. The vendor has addressed the issue in Hybrid Manager LTS version 1.3.3 and Innovation version 2025.12, urging customers to upgrade immediately. No known exploits have been reported in the wild as of the publication date. The root cause is a security policy oversight in the Istio Gateway configuration, emphasizing the importance of comprehensive access control definitions in service mesh environments.

For European organizations, this vulnerability poses a significant risk, especially for those relying on EnterpriseDB Hybrid Manager for database management and hybrid cloud orchestration. Exploitation could lead to unauthorized disclosure of sensitive operational or customer data, undermining confidentiality. Additionally, the ability to cause denial-of-service conditions could disrupt critical database services, impacting business continuity and availability. Given the network-exploitable nature and lack of authentication requirements, attackers could remotely target exposed Hybrid Manager instances, increasing the attack surface. Organizations in sectors such as finance, healthcare, telecommunications, and government—where database integrity and availability are paramount—face heightened risks. The potential for service disruption could affect compliance with European data protection regulations like GDPR, especially if sensitive data is exposed or service outages impact data processing activities. The absence of known exploits currently reduces immediate risk but should not lead to complacency, as the vulnerability is straightforward to exploit once discovered. Prompt patching is essential to mitigate risks of data breaches and operational disruptions.

European organizations using EnterpriseDB Hybrid Manager - LTS versions 1.2 or 1.3 should prioritize upgrading to version 1.3.3 or later to remediate this vulnerability. Beyond patching, organizations should audit their Istio Gateway configurations to ensure all gRPC endpoints are explicitly defined with appropriate authentication and authorization policies, preventing similar misconfigurations. Implement network segmentation and firewall rules to restrict access to Hybrid Manager services to trusted internal networks or VPNs, reducing exposure to external attackers. Enable and monitor detailed logging and alerting on access to gRPC endpoints to detect anomalous or unauthorized access attempts. Conduct regular security reviews of service mesh configurations, including Istio policies, to maintain strict access controls. Employ runtime application self-protection (RASP) or Web Application Firewalls (WAFs) capable of inspecting gRPC traffic where feasible. Finally, integrate vulnerability management processes to track and apply vendor patches promptly and verify remediation effectiveness through penetration testing or red team exercises focused on service mesh components.
