CVE-2020-2811 in WebLogic Server
Summary
by MITRE
Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Console). Supported versions that are affected are 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0 and 12.2.1.4.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebLogic Server. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle WebLogic Server, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle WebLogic Server accessible data as well as unauthorized read access to a subset of Oracle WebLogic Server accessible data. CVSS 3.0 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2020-2811 represents a critical security flaw within Oracle WebLogic Server's console component, specifically affecting multiple version lines including 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0, and 12.2.1.4.0. This vulnerability falls under the Common Weakness Enumeration category CWE-284, which addresses improper access control mechanisms within software systems. The flaw resides in the server's console interface, making it particularly dangerous as it provides a direct attack vector for malicious actors seeking to compromise enterprise applications that rely on Oracle Fusion Middleware infrastructure.
The technical exploitation of this vulnerability occurs through unauthenticated HTTP network access, requiring minimal prerequisites for successful compromise. Attackers can leverage this weakness to gain unauthorized access to critical server functions, enabling them to perform unauthorized update, insert, or delete operations on sensitive data within the WebLogic Server environment. Additionally, the vulnerability permits unauthorized read access to specific subsets of data that the server can access, creating potential exposure for confidential business information, user credentials, or proprietary application data. The CVSS 3.0 scoring system rates this vulnerability at 6.1, indicating a medium severity level with significant implications for both confidentiality and integrity, though it does not directly impact availability.
The operational impact of CVE-2020-2811 extends beyond the immediate WebLogic Server environment, as successful exploitation can potentially affect additional Oracle products within the Fusion Middleware ecosystem. This cascading effect aligns with the ATT&CK framework's concept of privilege escalation and lateral movement, where initial access to one component can provide opportunities for broader system compromise. The requirement for human interaction from a person other than the attacker suggests that the vulnerability may be triggered through social engineering or phishing campaigns targeting administrators, making it particularly insidious in enterprise environments where user trust is often leveraged for system access. Organizations running affected WebLogic Server versions face significant risk of data breaches, unauthorized modifications to critical applications, and potential disruption of business operations.
Mitigation strategies for this vulnerability should prioritize immediate patching of affected systems, as Oracle has released security updates specifically addressing this issue. Network segmentation and firewall restrictions can help limit exposure by restricting direct HTTP access to WebLogic Server console interfaces. Implementation of additional authentication controls, including multi-factor authentication for administrative access, can provide defense-in-depth measures against exploitation attempts. Regular security audits and monitoring of WebLogic Server console access logs should be conducted to detect potential unauthorized access attempts. Organizations should also consider implementing network intrusion detection systems that can identify suspicious HTTP traffic patterns associated with exploitation attempts. The vulnerability's classification under CWE-284 emphasizes the critical importance of proper access control implementation, and security teams must ensure that all administrative interfaces maintain robust authentication mechanisms to prevent unauthorized access to critical system functions.
