CVE-2025-54768 is a vulnerability identified in Xorux's LPAR2RRD product, version 8.04, involving improper access control on a privileged API endpoint. The flaw is categorized under CWE-648, which concerns the incorrect use of privileged APIs. Specifically, an API endpoint designed exclusively for web application administrators is not properly restricted and is accessible to lower-level read-only users. This endpoint permits downloading logs from the appliance configuration, which may contain sensitive information such as system configurations, user activity logs, or other operational data. The vulnerability does not require any authentication or user interaction to exploit, and can be triggered remotely over the network (AV:N). The CVSS v3.1 base score is 5.3, reflecting a medium severity level, with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact is limited to confidentiality (C:L), with no impact on integrity (I:N) or availability (A:N). No patches or known exploits are currently reported, but the exposure of sensitive logs could aid attackers in reconnaissance or further attacks. The vulnerability highlights a failure in enforcing proper access controls on privileged API endpoints within the LPAR2RRD web application, which is used for monitoring and capacity planning of IBM Power Systems and other virtualized environments.

For European organizations, the exposure of sensitive appliance configuration logs could lead to information disclosure that aids attackers in mapping network infrastructure, identifying system weaknesses, or harvesting credentials and configuration details. This could facilitate subsequent targeted attacks, lateral movement, or data breaches. Organizations relying on LPAR2RRD for monitoring critical IBM Power Systems or virtualized environments may have sensitive operational data exposed to unauthorized users within their network or potentially from external sources if the application is internet-facing. While the vulnerability does not directly compromise system integrity or availability, the confidentiality breach can undermine trust and compliance with data protection regulations such as GDPR. The risk is heightened in sectors with stringent data privacy requirements, including finance, healthcare, and government agencies. Additionally, the ease of exploitation without authentication increases the threat level, especially in environments with weak network segmentation or insufficient internal access controls.

1. Monitor Xorux communications and apply vendor-provided patches or updates as soon as they become available to address this vulnerability. 2. Implement strict network segmentation and firewall rules to restrict access to the LPAR2RRD web application and its API endpoints, limiting exposure to trusted administrative networks only. 3. Review and audit user roles and permissions within LPAR2RRD to ensure that read-only users cannot access privileged API endpoints. 4. Employ web application firewalls (WAF) with custom rules to detect and block unauthorized API calls targeting sensitive endpoints. 5. Conduct regular security assessments and penetration testing focused on API access controls to identify similar privilege escalation or information disclosure issues. 6. Monitor logs and alerts for unusual access patterns to the appliance configuration logs or API endpoints. 7. Educate administrators and users about the risks of exposing monitoring tools and enforce strong authentication and authorization policies. 8. If feasible, disable or restrict the vulnerable API endpoint until a patch is available.
