CVE-2017-7568 in OnCommand Unified Manager for 7-mode
Summary
by MITRE
NetApp OnCommand Unified Manager for 7-Mode (core package) versions prior to 5.2.3 may disclose sensitive LDAP account information to authenticated users when the LDAP authentication configuration is tested via the user interface.

The vulnerability identified as CVE-2017-7568 affects NetApp OnCommand Unified Manager for 7-Mode core package versions before 5.2.3, representing a significant information disclosure flaw that compromises authentication security. This issue manifests when users test LDAP authentication configurations through the graphical user interface, creating a pathway for authenticated users to access sensitive credential information that should remain protected within the system's internal configuration mechanisms.
The technical flaw resides in the improper handling of LDAP authentication testing processes within the unified manager's user interface. When administrators or authorized users perform LDAP configuration tests, the system inadvertently exposes sensitive account information including usernames, passwords, or other authentication credentials through error messages, debug output, or direct data retrieval mechanisms. This vulnerability operates at the application layer and represents a classic case of insufficient input validation and output sanitization, where the system fails to properly restrict information flow between different privilege levels.
The operational impact of this vulnerability extends beyond simple credential exposure, as it creates potential attack vectors for both internal and external adversaries who gain authenticated access to the system. An attacker with valid credentials could leverage this flaw to escalate privileges, conduct reconnaissance for additional targets, or establish persistence within the network infrastructure. The vulnerability directly violates security principles outlined in the OWASP Top Ten 2017, specifically addressing information exposure and insufficient logging and monitoring. From an attack perspective, this flaw aligns with techniques described in the MITRE ATT&CK framework under credential access and privilege escalation categories, potentially enabling adversaries to move laterally within the network environment.
Organizations utilizing affected NetApp versions face significant risk of credential compromise and unauthorized access to their storage infrastructure, particularly in environments where LDAP authentication is heavily relied upon for user management. The vulnerability's impact is magnified in enterprise environments where centralized authentication systems are critical for maintaining security boundaries and access controls. Security teams should prioritize immediate remediation through patching to version 5.2.3 or later, while implementing additional monitoring for unusual authentication testing activities that might indicate exploitation attempts. The flaw demonstrates the importance of proper access control implementation and secure coding practices, particularly when handling sensitive authentication data within web-based management interfaces. Organizations should also consider implementing network segmentation and privilege-based access controls to limit the potential damage from such information disclosure vulnerabilities.
