CVE-2017-3420 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle CRM Technical Foundation component of Oracle E-Business Suite (subcomponent: User Interface). The supported version that is affected is 12.1.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle CRM Technical Foundation. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle CRM Technical Foundation, 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 CRM Technical Foundation accessible data as well as unauthorized update, insert or delete access to some of Oracle CRM Technical Foundation accessible data. CVSS v3.0 Base Score 8.2 (Confidentiality and Integrity impacts).

The vulnerability identified as CVE-2017-3420 resides within the Oracle CRM Technical Foundation component of Oracle E-Business Suite, specifically affecting the User Interface subcomponent in version 12.1.3. This flaw represents a significant security weakness that exposes organizations to potential unauthorized access and data compromise. The vulnerability operates within the broader Oracle E-Business Suite ecosystem, which serves as a critical enterprise resource planning platform for numerous organizations worldwide. The affected component handles user interface functionalities and interacts with underlying database systems, making it a prime target for attackers seeking to exploit weaknesses in enterprise applications.
This vulnerability manifests as an easily exploitable flaw that allows unauthenticated attackers to gain network access through HTTP protocols without requiring any prior authentication credentials. The technical nature of the vulnerability stems from insufficient input validation and access control mechanisms within the User Interface component, creating pathways for malicious actors to bypass normal security controls. The vulnerability's classification as easily exploitable indicates that attackers can leverage automated tools or simple manual techniques to identify and exploit the weakness, significantly reducing the barrier to successful attacks. The flaw operates at the application layer and can be triggered through standard web-based interactions, making it particularly dangerous in environments where the application is exposed to external networks.
The operational impact of this vulnerability extends beyond the immediate Oracle CRM Technical Foundation component, potentially affecting additional products within the Oracle E-Business Suite ecosystem. Successful exploitation can result in unauthorized access to critical data repositories, allowing attackers to view sensitive information including customer records, financial data, and business intelligence. The vulnerability's ability to grant complete access to all accessible data represents a severe risk to data confidentiality and integrity, as attackers can not only read information but also modify, insert, or delete data within the system. This comprehensive access capability aligns with CVSS v3.0 base score of 8.2, reflecting the high potential for data compromise and system disruption.
The requirement for human interaction from individuals other than the attacker suggests that this vulnerability may be exploited through social engineering or targeted attacks where users are tricked into interacting with malicious content. This aspect of the vulnerability requires organizations to consider both technical and human factors in their security posture. The attack vector through HTTP protocols indicates that the vulnerability can be exploited from remote locations without physical access to the network, making it particularly concerning for organizations with internet-facing applications. Security professionals should note that this vulnerability demonstrates the importance of proper input validation and access control implementation in web-based applications, as outlined in CWE categories related to input validation and privilege escalation.
Organizations should implement immediate mitigations including applying the relevant Oracle security patches and updates, implementing network segmentation to limit access to the affected components, and establishing robust monitoring for suspicious HTTP traffic patterns. Additional defensive measures should include restricting access to the Oracle E-Business Suite through firewalls, implementing strong authentication mechanisms, and conducting regular security assessments of the application environment. The vulnerability's impact on multiple products within the Oracle E-Business Suite ecosystem underscores the need for comprehensive security management and coordinated patching strategies across all affected components. Security teams should also consider implementing intrusion detection systems and monitoring for indicators of compromise that may signal exploitation attempts against this vulnerability.
