CVE-2020-2644 in Enterprise Manager Base Platform
Summary
by MITRE
Vulnerability in the Enterprise Manager Base Platform product of Oracle Enterprise Manager (component: Oracle Management Service). Supported versions that are affected are 12.1.0.5, 13.2.0.0 and 13.3.0.0. Easily exploitable vulnerability allows high privileged attacker with network access via HTTP to compromise Enterprise Manager Base Platform. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Enterprise Manager Base Platform accessible data as well as unauthorized update, insert or delete access to some of Enterprise Manager Base Platform accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Enterprise Manager Base Platform. CVSS 3.0 Base Score 6.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:L).

The vulnerability identified as CVE-2020-2644 resides within Oracle Enterprise Manager's Base Platform component, specifically affecting the Oracle Management Service which serves as a critical infrastructure element for enterprise monitoring and management. This vulnerability impacts multiple versions including 12.1.0.5, 13.2.0.0, and 13.3.0.0, representing a significant attack surface that affects organizations relying on Oracle's enterprise management solutions. The vulnerability classification as easily exploitable indicates that attackers with minimal technical expertise can leverage this weakness, making it particularly concerning for enterprise environments where such systems often contain sensitive operational data and control mechanisms.
The technical flaw manifests through insufficient authentication and authorization controls within the Oracle Management Service, allowing attackers with high privileges and network access via HTTP to bypass normal security restrictions. This represents a critical weakness in the authentication framework where the system fails to properly validate user credentials or session tokens before granting access to sensitive resources. The vulnerability's CVSS score of 6.0 reflects the balance between the attack vector complexity and the potential impact on confidentiality, integrity, and availability. The attack vector AV:N indicates network-based exploitation without requiring physical access, while the high privilege requirement PR:H suggests that attackers must already possess elevated credentials or have achieved some level of system compromise before targeting this specific vulnerability.
The operational impact of successful exploitation extends beyond simple data access, encompassing complete compromise of enterprise management platforms that typically house critical business data, configuration settings, and operational controls. Attackers can achieve unauthorized access to all accessible data within the platform, potentially exposing sensitive operational information, system configurations, and business-critical metrics. The ability to perform unauthorized updates, inserts, and deletes creates a significant integrity risk where attackers can modify system parameters, alter monitoring configurations, or corrupt management data. Additionally, the partial denial of service capability allows attackers to disrupt platform operations, potentially affecting system availability and operational continuity. This vulnerability directly maps to CWE-287 which addresses improper authentication issues, and aligns with ATT&CK technique T1078 for valid accounts and T1499 for endpoint disruption, representing both credential exploitation and system compromise phases.
Organizations should implement immediate mitigations including network segmentation to restrict access to management services, implementation of robust access controls and monitoring of HTTP traffic, and deployment of intrusion detection systems to identify suspicious activities targeting the Oracle Management Service. Regular patching and vulnerability assessment programs should be prioritized to address this weakness and similar authentication vulnerabilities. The platform should be configured with least privilege access controls, and administrators should implement multi-factor authentication where possible to reduce the risk of credential compromise. Network access controls should limit HTTP access to management services to trusted IP addresses and implement additional security layers such as web application firewalls to protect against exploitation attempts. Continuous monitoring of system logs and network traffic patterns can help detect unauthorized access attempts and provide early warning of potential exploitation activities.
