CVE-2020-2835 in Marketing
Summary
by MITRE
Vulnerability in the Oracle Marketing product of Oracle E-Business Suite (component: Marketing Administration). 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 Marketing. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Marketing, 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 Marketing accessible data as well as unauthorized update, insert or delete access to some of Oracle Marketing 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 described in CVE-2020-2835 represents a critical security flaw within Oracle Marketing component of the Oracle E-Business Suite ecosystem. This weakness exists specifically in versions 12.1.1 through 12.1.3, making a substantial portion of the Oracle E-Business Suite installations susceptible to exploitation. The vulnerability falls under the category of insufficient authentication mechanisms and has been classified with a CVSS base score of 8.2, indicating a high severity threat level that demands immediate attention from security administrators and system operators. The attack vector requires network access via HTTP protocol, making it particularly dangerous as it can be exploited from remote locations without requiring prior authentication credentials.
The technical nature of this vulnerability stems from inadequate input validation and authentication controls within the Oracle Marketing administration interface. Attackers can exploit this weakness through unauthenticated network connections, potentially gaining unauthorized access to sensitive marketing data and system resources. The vulnerability's design allows for both confidentiality and integrity impacts, meaning that successful exploitation could result in unauthorized data access or modification, with potential for complete data compromise. The CVSS vector analysis reveals that while the attack requires human interaction from an unsuspecting user, the actual exploitation process itself does not require privileged access, making it particularly dangerous in environments where users might inadvertently trigger malicious actions through legitimate application interactions. This characteristic aligns with CWE-287, which addresses improper handling of authentication tokens and credentials, and reflects the broader category of authentication bypass vulnerabilities.
The operational impact of this vulnerability extends beyond the immediate Oracle Marketing component, as indicated by the CVSS score that includes a "C" (Confidentiality) impact and "S:C" (Scope: Changed) classification. This means that while the initial attack may target the Marketing module, the consequences can propagate to affect other interconnected Oracle E-Business Suite components. The vulnerability enables attackers to gain unauthorized access to critical data repositories and potentially modify or delete information within the marketing system, creating significant business disruption and data integrity concerns. Organizations utilizing affected Oracle E-Business Suite versions face substantial risk of data breaches, regulatory compliance violations, and potential financial losses due to unauthorized access to customer marketing information and business data. The vulnerability's ability to provide unauthorized update, insert, or delete access to Oracle Marketing accessible data represents a particularly concerning aspect that could lead to data corruption, manipulation, or complete system compromise.
Organizations should prioritize immediate remediation of this vulnerability through the application of Oracle's official security patches and updates. The recommended mitigation strategy includes implementing network segmentation controls to limit access to Oracle Marketing components, deploying web application firewalls to monitor and filter HTTP traffic, and conducting comprehensive security assessments of all affected Oracle E-Business Suite installations. Security teams should also establish monitoring procedures to detect potential exploitation attempts and implement user access controls to minimize the risk of successful social engineering attacks that require human interaction. From an ATT&CK framework perspective, this vulnerability aligns with techniques involving credential access and privilege escalation, particularly those that leverage application-level weaknesses to bypass authentication mechanisms. Organizations must also consider the broader implications for their overall security posture, as the compromise of one Oracle Marketing component could potentially provide attackers with additional attack surface within the enterprise network infrastructure. Regular security assessments and vulnerability management programs should be enhanced to identify similar weaknesses in other Oracle E-Business Suite components and ensure comprehensive protection across all enterprise applications.
