CVE-2025-8530 is a vulnerability identified in the elunez eladmin software versions 2.0 through 2.7. The issue stems from the use of default credentials within the configuration file located at eladmin-system\src\main\resources\config\application-prod.yml, specifically related to the Druid component. This vulnerability allows an attacker to manipulate the login-username and login-password parameters remotely without requiring any authentication or user interaction. The vulnerability is classified as problematic with a CVSS 4.0 base score of 6.9, indicating a medium severity level. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The vulnerability impacts confidentiality to a limited extent (VC:L) but does not affect integrity or availability. The exploit has been publicly disclosed, although no known exploits are currently reported in the wild. The root cause is the failure to change or disable default credentials in the Druid monitoring or management interface, which is commonly used for database connection pool monitoring and management. This allows an attacker to gain unauthorized access to the system remotely, potentially leading to information disclosure or further exploitation depending on the privileges of the compromised component.

For European organizations using elunez eladmin versions 2.0 to 2.7, this vulnerability poses a significant risk of unauthorized remote access due to default credential usage. Attackers could leverage this to access sensitive configuration or monitoring data, potentially exposing internal system details or user information. While the direct impact on integrity and availability is limited, the confidentiality breach could facilitate subsequent attacks such as lateral movement or privilege escalation. Organizations in sectors with stringent data protection requirements (e.g., finance, healthcare, government) may face compliance risks under GDPR if sensitive data is exposed. Additionally, the public disclosure of the exploit increases the likelihood of opportunistic attacks, especially if patches or mitigations are not promptly applied. The remote and unauthenticated nature of the vulnerability makes it particularly dangerous in environments where eladmin is exposed to untrusted networks or the internet without adequate network segmentation or access controls.

To mitigate CVE-2025-8530, European organizations should immediately audit their eladmin installations to identify affected versions (2.0 through 2.7). Specific mitigation steps include: 1) Changing default credentials in the application-prod.yml configuration file to strong, unique usernames and passwords; 2) Restricting network access to the Druid component by implementing firewall rules or network segmentation to limit exposure to trusted internal networks only; 3) Monitoring logs for unauthorized login attempts or unusual access patterns to the Druid interface; 4) Applying any available patches or updates from the vendor as soon as they are released; 5) If patching is not immediately possible, disabling or removing the Druid monitoring component temporarily to eliminate the attack surface; 6) Implementing multi-factor authentication (MFA) if supported by the application to add an additional layer of security; 7) Conducting regular security assessments and penetration testing focused on configuration weaknesses and default credential usage. These measures go beyond generic advice by focusing on configuration hardening, network controls, and active monitoring tailored to the specifics of this vulnerability.
