CVE-2020-2840 in E-Business Intelligence
Summary
by MITRE
Vulnerability in the Oracle E-Business Intelligence product of Oracle E-Business Suite (component: DBI Setups). Supported versions that are affected are 12.1.1-12.1.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle E-Business Intelligence. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle E-Business Intelligence, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle E-Business Intelligence accessible data as well as unauthorized update, insert or delete access to some of Oracle E-Business Intelligence accessible data. CVSS 3.0 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2020-2840 represents a critical security flaw within Oracle E-Business Intelligence component of the Oracle E-Business Suite ecosystem. This vulnerability specifically affects DBI Setups functionality and impacts versions 12.1.1 through 12.1.3, making it a significant concern for organizations utilizing these older releases. The flaw exists within the web-based interface of Oracle E-Business Intelligence, creating an attack surface that can be exploited by unauthenticated remote adversaries. The vulnerability's classification as easily exploitable indicates that attackers require minimal technical expertise to leverage this weakness, while the CVSS 3.0 score of 8.2 reflects the substantial risk posed to affected systems. The vector analysis reveals that network-based attacks can be conducted without authentication requirements, though human interaction is necessary for successful exploitation, suggesting that social engineering or user engagement may be required to complete the attack chain.
The technical implementation of this vulnerability stems from insufficient input validation and access control mechanisms within the DBI Setups component of Oracle E-Business Intelligence. Attackers can leverage HTTP network connections to access sensitive functionality that should otherwise be restricted to authorized users only. The flaw allows for unauthorized access to critical data within the Oracle E-Business Intelligence environment, potentially enabling full data compromise across all accessible database objects. Additionally, the vulnerability permits unauthorized modification operations including updates, inserts, and deletions of data, creating a comprehensive attack surface that extends beyond simple information disclosure. This type of vulnerability aligns with CWE-284 (Improper Access Control) and CWE-352 (Cross-Site Request Forgery) classifications, demonstrating how inadequate access controls can lead to severe privilege escalation scenarios. The attack requires human interaction from users other than the attacker, indicating that the vulnerability may be exploited through social engineering tactics or by tricking users into performing specific actions that trigger the malicious code execution.
The operational impact of CVE-2020-2840 extends far beyond the immediate Oracle E-Business Intelligence environment, potentially affecting related systems and applications within the broader Oracle E-Business Suite ecosystem. Organizations utilizing affected versions face significant risks including data breaches, financial loss, regulatory compliance violations, and operational disruption. The vulnerability's ability to enable complete access to all Oracle E-Business Intelligence accessible data creates a substantial risk for intellectual property theft, customer information compromise, and financial data exposure. The integrity impact component of the CVSS score indicates that attackers can modify or delete data within the system, potentially causing operational disruption or data corruption that could affect business processes and decision-making capabilities. The fact that attacks may significantly impact additional products suggests that the vulnerability could serve as a stepping stone for broader attacks within enterprise networks, particularly in environments where Oracle E-Business Suite components are interconnected with other business applications.
Organizations should implement immediate mitigations to address this vulnerability including applying Oracle's security patches and updates as soon as they become available through Oracle Critical Patch Updates. Network segmentation and firewall rules should be implemented to restrict access to Oracle E-Business Intelligence components, particularly limiting HTTP access to trusted networks only. Enhanced monitoring and logging of database access patterns should be deployed to detect potential exploitation attempts, with particular attention to unusual data access or modification activities. Access controls should be reviewed and strengthened, ensuring that only authorized personnel have access to DBI Setups functionality and related administrative interfaces. Security awareness training should be conducted to educate users about social engineering tactics that may be used to exploit this vulnerability. The vulnerability's classification under the ATT&CK framework would place it within the credential access and privilege escalation domains, emphasizing the need for comprehensive defensive measures. Regular vulnerability assessments and penetration testing should be conducted to identify and remediate similar weaknesses throughout the Oracle E-Business Suite environment, ensuring that the organization maintains a robust security posture against evolving threats.
