CVE-2025-50068 is a vulnerability identified in Oracle Corporation's MySQL Cluster product, affecting versions 8.0.0 through 8.0.42, 8.4.0 through 8.4.5, and 9.0.0 through 9.3.0. The vulnerability resides in the cluster component of MySQL Cluster and is characterized as easily exploitable by a high privileged attacker who already has logon access to the infrastructure where the MySQL Cluster is running. The attack vector is local (AV:L), requiring low attack complexity (AC:L) and high privileges (PR:H), with no user interaction needed (UI:N). The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H), meaning a successful exploit could lead to a complete takeover of the MySQL Cluster environment. The CVSS 3.1 base score is 6.7, categorizing it as a medium severity vulnerability. Although no known exploits are currently reported in the wild, the potential for a full cluster compromise makes this a significant risk for environments relying on MySQL Cluster for critical data storage and processing. The vulnerability requires the attacker to have high privileges on the host infrastructure, indicating that initial access control failures or insider threats could be leveraged to exploit this issue. The lack of available patches at the time of publication suggests that organizations must prioritize monitoring and mitigation strategies until official fixes are released.

For European organizations, the impact of CVE-2025-50068 can be substantial, especially for those relying on MySQL Cluster for high-availability, distributed database services in sectors such as finance, telecommunications, manufacturing, and public administration. A successful exploit could lead to unauthorized data access, data manipulation, or service disruption, affecting business continuity and potentially leading to regulatory non-compliance under GDPR due to data breaches. The compromise of MySQL Cluster could also facilitate lateral movement within the network, enabling attackers to escalate privileges or access other critical systems. Given the requirement for high privileges to exploit this vulnerability, organizations with insufficient internal access controls or inadequate monitoring of privileged accounts are at higher risk. Additionally, the impact on availability could disrupt services dependent on the cluster, leading to operational downtime and financial losses. The medium severity rating should not downplay the risk, as the potential for full cluster takeover elevates the threat in environments where MySQL Cluster is a core component.

To mitigate the risk posed by CVE-2025-50068, European organizations should implement the following specific measures: 1) Restrict and tightly control administrative and privileged access to the infrastructure hosting MySQL Cluster, employing the principle of least privilege and robust identity and access management (IAM) policies. 2) Implement comprehensive monitoring and alerting for unusual activities on hosts running MySQL Cluster, focusing on privilege escalations and access anomalies. 3) Segment the network to isolate MySQL Cluster nodes from less trusted network segments, reducing the attack surface and limiting lateral movement opportunities. 4) Apply strict host hardening and ensure that only authorized personnel can log on to the infrastructure where MySQL Cluster operates. 5) Prepare for patch deployment by closely monitoring Oracle's security advisories and testing patches in controlled environments before production rollout. 6) Conduct regular security audits and penetration testing focused on privileged access controls and MySQL Cluster configurations. 7) Employ multi-factor authentication (MFA) for all administrative access to infrastructure hosting MySQL Cluster to reduce the risk of credential compromise. 8) Maintain up-to-date backups of MySQL Cluster data and configurations to enable rapid recovery in case of compromise or disruption.
