The vulnerability identified as CVE-2019-10159 affects cfme-gemset versions 5.10.4.3 and earlier, as well as 5.9.9.3 and earlier, representing a critical authorization flaw in the migration log controller component. This issue stems from inadequate access controls that permit unauthorized users to access sensitive virtual machine migration logs. The affected system operates within cloud infrastructure management environments where migration activities are common and involve critical operational data. The vulnerability specifically targets the authorization mechanisms that should normally restrict access to migration logs based on user privileges and roles.
The technical flaw manifests in the improper implementation of access control checks within the migration log controller, which fails to validate user permissions before exposing migration log data. This weakness allows an attacker with minimal privileges to bypass normal authorization protocols and retrieve comprehensive migration log information from the system. The vulnerability falls under the category of insufficient authorization as classified by CWE-285, which specifically addresses cases where systems fail to properly enforce access controls. The migration logs typically contain detailed information about virtual machine movements including source and destination hosts, timestamps, migration status, and potentially sensitive operational details that could aid in further attack planning.
The operational impact of this vulnerability extends beyond simple data exposure, as migration logs often contain information that could reveal system architecture, operational patterns, and potential security weaknesses within the cloud infrastructure. An attacker could leverage this leaked information to understand migration schedules, identify vulnerable systems during migration windows, or correlate migration activities with other security events. This information leakage creates opportunities for more sophisticated attacks including privilege escalation, lateral movement, or targeted exploitation of systems during migration processes. The vulnerability particularly affects organizations using Red Hat CloudForms or similar cloud management platforms where VM migration activities are frequent and sensitive data is routinely processed.
Mitigation strategies should focus on implementing proper access controls and authorization checks within the migration log controller component. Organizations should immediately upgrade to cfme-gemset versions that address this vulnerability, ensuring that all users undergo proper authentication and authorization validation before accessing migration logs. The fix should incorporate role-based access control mechanisms that align with the principle of least privilege, restricting migration log access to authorized personnel only. Security teams should also implement monitoring and logging of access attempts to migration logs to detect potential unauthorized access patterns. This vulnerability demonstrates the importance of proper authorization implementation and aligns with ATT&CK technique T1078 which covers valid accounts and privilege escalation through unauthorized access to system resources. Organizations should conduct comprehensive security assessments of their cloud management platforms to identify similar authorization flaws in other components and ensure that all access control mechanisms are properly enforced across the entire system architecture.
