CVE-2025-0736 is a vulnerability identified in the Infinispan data grid platform, specifically when integrated with JGroups using the JDBC_PING protocol. The flaw arises from the application logging sensitive information such as configuration parameters or credentials into log files without adequate sanitization or protection. This results in the insertion of sensitive data into logs, which can be accessed by unauthorized users who have local access to the system. The vulnerability has a CVSS 3.1 base score of 5.5, indicating medium severity, with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N. This means the attack requires local access with low privileges, no user interaction, and impacts confidentiality significantly while not affecting integrity or availability. The exposure of sensitive information in logs can lead to unauthorized access or privilege escalation if attackers leverage leaked credentials or configuration details. The issue does not currently have known exploits in the wild, and no patches or fixes have been explicitly linked yet. The vulnerability highlights the risk of improper logging practices in distributed caching systems and the importance of securing log data, especially in clustered environments where JDBC_PING is used for discovery and communication.

For European organizations, the exposure of sensitive information in logs can have serious consequences, including unauthorized access to critical systems, data breaches, and compliance violations under regulations such as GDPR. Organizations relying on Infinispan for distributed caching or clustering, particularly in sectors like finance, telecommunications, and government, may face increased risk if attackers gain local access to systems and extract sensitive credentials or configuration details from logs. This can facilitate lateral movement within networks, privilege escalation, or targeted attacks on critical infrastructure. The confidentiality breach could undermine trust and lead to financial and reputational damage. Since the vulnerability requires local access, the risk is higher in environments where multiple users share systems or where attackers can gain footholds through other means. The lack of impact on integrity and availability reduces the risk of direct service disruption but does not diminish the threat posed by leaked sensitive data.

European organizations should immediately audit their Infinispan deployments using JGroups with JDBC_PING to identify logging configurations that may expose sensitive information. Specific mitigations include: 1) Disable or restrict logging of sensitive configuration parameters and credentials; 2) Implement strict access controls on log files to limit access to authorized personnel only; 3) Use log sanitization or filtering mechanisms to redact sensitive data before writing to logs; 4) Monitor logs for unexpected sensitive data exposure and implement alerting; 5) Apply the principle of least privilege to local user accounts to reduce the risk of unauthorized access; 6) Segregate environments to minimize local access risks; 7) Stay updated with vendor advisories and apply patches or updates as they become available; 8) Conduct regular security training to raise awareness about secure logging practices; 9) Consider using encrypted logging solutions to protect log confidentiality; 10) Review and harden overall system security to prevent initial local access by attackers.
