CVE-2020-2834 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 identified as CVE-2020-2834 represents a critical security flaw within Oracle Marketing component of the Oracle E-Business Suite, specifically affecting versions 12.1.1 through 12.1.3. This vulnerability operates at the application layer and demonstrates characteristics that align with CWE-284 (Improper Access Control) and CWE-352 (Cross-Site Request Forgery) within the Common Weakness Enumeration framework. The flaw exists in the Marketing Administration module where insufficient authentication mechanisms permit unauthorized access to sensitive marketing data and functionality.
The technical implementation of this vulnerability stems from inadequate input validation and access control mechanisms within the HTTP request processing pipeline of the Oracle Marketing component. Attackers can exploit this weakness through unauthenticated network connections using standard HTTP protocols without requiring any privileged credentials or specialized tools. The vulnerability's CVSS 3.0 score of 8.2 reflects its high severity, indicating that while it requires human interaction to execute successfully, the potential impact is substantial. The vector AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N demonstrates that network-based attacks can be launched with low complexity, no prior privileges required, and that user interaction is necessary but that the scope of impact extends beyond the vulnerable component itself.
The operational impact of this vulnerability extends far beyond the immediate Marketing module, as evidenced by the CVSS scope vector indicating a complete impact (S:C) on the system. Successful exploitation enables attackers to gain unauthorized access to critical marketing data including customer information, campaign details, and strategic business intelligence. The vulnerability also permits unauthorized modification of data through update, insert, and delete operations, potentially compromising data integrity and availability. This makes the vulnerability particularly dangerous in enterprise environments where marketing data often contains sensitive customer information and business-critical strategic assets.
Organizations affected by this vulnerability should implement immediate mitigations including network segmentation to restrict access to Oracle Marketing components, deployment of web application firewalls to monitor and filter HTTP requests, and implementation of additional authentication layers. The vulnerability aligns with ATT&CK technique T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS) as attackers may leverage this weakness to establish persistent access to marketing systems. Regular security assessments and patch management procedures should be enhanced to prevent similar vulnerabilities from emerging in other Oracle E-Business Suite components, particularly given the interconnected nature of these applications and the potential for lateral movement within compromised networks.
