CVE-2025-8525 is an information disclosure vulnerability identified in Exrick xboot versions up to 3.3.4. The vulnerability stems from a problematic component within the Spring Boot Admin or Spring Actuator integration used by xboot. Spring Boot Admin and Actuator are commonly used for monitoring and managing Spring Boot applications, exposing endpoints that provide operational information. The vulnerability allows an unauthenticated remote attacker to manipulate the affected component to disclose sensitive information. The exact nature of the information disclosed is unspecified, but given the context, it could include configuration details, environment variables, or other internal application data that could aid further attacks. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The attack vector is network-based (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and no authentication (AT:N), making it relatively easy to exploit remotely. The impact is limited to confidentiality (VC:L), with no impact on integrity, availability, or other security properties. Although no exploits are currently known to be in the wild, the public disclosure of the exploit increases the risk of exploitation. The vulnerability affects multiple versions of xboot from 3.3.0 through 3.3.4, and no official patches or mitigations have been linked yet. Organizations using these versions of Exrick xboot with Spring Boot Admin/Actuator components should consider this vulnerability a significant risk to sensitive information exposure.

For European organizations, the information disclosure vulnerability in Exrick xboot could lead to leakage of sensitive internal data such as configuration settings, credentials, or system details. This could facilitate further targeted attacks, including privilege escalation, lateral movement, or data exfiltration. Organizations in sectors with high regulatory requirements for data protection, such as finance, healthcare, and critical infrastructure, could face compliance risks if sensitive information is exposed. The ease of remote exploitation without authentication increases the threat level, especially for internet-facing applications using vulnerable versions. While the vulnerability does not directly impact system integrity or availability, the confidentiality breach could undermine trust, cause reputational damage, and potentially lead to secondary attacks. European entities relying on Exrick xboot for application management or monitoring should prioritize assessment and remediation to prevent exploitation.

1. Immediate upgrade: Organizations should upgrade Exrick xboot to a version beyond 3.3.4 once a patched release is available. 2. Restrict access: Limit network exposure of Spring Boot Admin and Actuator endpoints by implementing network segmentation, firewall rules, or VPN access to ensure only trusted administrators can reach these interfaces. 3. Authentication and authorization: Enforce strong authentication and role-based access control on management endpoints to prevent unauthorized access. 4. Monitoring and logging: Enable detailed logging and monitor access to Spring Boot Admin/Actuator endpoints for unusual or unauthorized activity. 5. Temporary workarounds: If patching is not immediately possible, consider disabling or restricting sensitive actuator endpoints that expose detailed information. 6. Conduct security assessments: Perform penetration testing and code reviews focusing on application management interfaces to identify and remediate similar vulnerabilities. 7. Stay informed: Subscribe to vendor advisories and CVE databases to promptly apply security updates.
