CVE-2017-7345 in OnCommand Performance Manager
Summary
by MITRE
NetApp OnCommand Performance Manager and OnCommand Unified Manager for Clustered Data ONTAP before 7.1P1 improperly bind the Java Management Extension Remote Method Invocation (aka JMX RMI) service to the network, which allows remote attackers to obtain sensitive information via unspecified vectors.

The vulnerability identified as CVE-2017-7345 affects NetApp OnCommand Performance Manager and OnCommand Unified Manager for Clustered Data ONTAP versions prior to 7.1P1, representing a critical security flaw in the Java Management Extensions Remote Method Invocation service implementation. This issue stems from improper network binding of the JMX RMI service, which exposes sensitive system information to remote attackers without proper authentication or authorization mechanisms. The flaw exists at the application layer and specifically targets the management interface components that are essential for monitoring and managing NetApp storage systems in clustered environments.
The technical root cause of this vulnerability lies in the insecure configuration of the JMX RMI service, which typically operates on well-known ports and provides administrative capabilities for monitoring and managing Java applications. When the service binds to all network interfaces rather than restricting access to localhost or specific trusted networks, it creates an attack surface that allows remote adversaries to establish connections and potentially extract sensitive operational data. This misconfiguration enables attackers to gather information about the system's performance metrics, configuration parameters, and potentially other administrative details that could be leveraged for further exploitation. The vulnerability falls under the category of improper information exposure as defined by CWE-200, where sensitive data is accessible to unauthorized parties due to inadequate access controls.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with valuable intelligence about the storage infrastructure that could be used to plan more sophisticated attacks. Remote attackers could potentially use the gathered information to identify system weaknesses, understand network topology, and determine the specific versions and configurations of the software in use. This intelligence could then be leveraged for privilege escalation attempts, denial of service attacks, or as a stepping stone for more advanced exploitation techniques. The vulnerability affects organizations that rely on NetApp's management tools for monitoring their clustered data ontap environments, potentially exposing critical infrastructure data to unauthorized access.
Organizations should implement immediate mitigations to address this vulnerability by upgrading to NetApp OnCommand Performance Manager and OnCommand Unified Manager version 7.1P1 or later, which contains the necessary security patches. Network segmentation should be enforced to limit access to the JMX RMI ports, and firewall rules should be implemented to restrict connections to only trusted administrative networks. Additionally, security monitoring should be enhanced to detect unusual access patterns to management interfaces, and regular security assessments should be conducted to identify similar misconfigurations in other system components. The mitigation strategies align with ATT&CK technique T1082 for system information discovery and T1046 for network service scanning, which attackers might employ to exploit such vulnerabilities. Organizations should also consider implementing network access controls and monitoring solutions that can detect unauthorized access attempts to management interfaces, as recommended in industry best practices for securing enterprise storage systems.
