CVE-2025-0736 is a medium-severity vulnerability identified in Infinispan, a distributed in-memory key/value data store and cache, specifically when used in conjunction with JGroups and the JDBC_PING protocol. The vulnerability arises from the inadvertent insertion of sensitive information—such as configuration details or credentials—into log files. This occurs due to improper handling or excessive logging of sensitive data during the cluster discovery or communication phases facilitated by JGroups' JDBC_PING mechanism. Since logs are often accessible to various system users or administrators, the exposure of sensitive information in these logs can lead to unauthorized access if malicious actors gain access to the log files. The vulnerability has a CVSS 3.1 base score of 5.5, indicating a medium level of severity. The attack vector is local (AV:L), requiring low attack complexity (AC:L) and low privileges (PR:L), but no user interaction (UI:N). The impact is primarily on confidentiality (C:H), with no direct impact on integrity or availability. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. The vulnerability was published in January 2025 and assigned by Red Hat. The affected versions are not explicitly detailed beyond placeholders, but the issue is relevant to deployments using Infinispan with JGroups and JDBC_PING. This flaw highlights the risk of sensitive data leakage through logging mechanisms, which is a common vector for information disclosure in distributed systems.

For European organizations, the exposure of sensitive configuration details or credentials in log files can have significant security implications. Such information leakage can facilitate lateral movement within networks, unauthorized access to critical systems, or escalation of privileges. Organizations relying on Infinispan for caching or data storage in clustered environments—particularly those using JGroups with JDBC_PING—may inadvertently expose sensitive data if logs are not properly secured or sanitized. This can lead to breaches of confidentiality, regulatory non-compliance (e.g., GDPR), and potential reputational damage. The local attack vector means that attackers typically need some level of access to the system or network, which could be achieved through compromised internal accounts or insider threats. Given the medium severity and the lack of impact on integrity or availability, the primary risk is data confidentiality loss, which can be leveraged for further attacks. European enterprises in sectors such as finance, telecommunications, and government, which often deploy distributed caching solutions, could be particularly at risk if proper logging hygiene and access controls are not enforced.

To mitigate this vulnerability, European organizations should: 1) Review and audit logging configurations in Infinispan and JGroups, especially focusing on JDBC_PING usage, to ensure sensitive information is not logged. 2) Implement strict access controls and monitoring on log files to prevent unauthorized access. 3) Employ log sanitization or redaction techniques to remove or mask sensitive data before writing to logs. 4) Update to patched versions of Infinispan and JGroups once available; until then, consider disabling JDBC_PING if feasible or restricting its use to trusted environments. 5) Conduct regular security assessments and penetration testing focusing on information disclosure through logs. 6) Educate developers and system administrators about secure logging practices and the risks of sensitive data exposure. 7) Monitor threat intelligence feeds for any emerging exploits related to this CVE to respond promptly.
