CVE-2017-3427 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle One-to-One Fulfillment component of Oracle E-Business Suite (subcomponent: User Interface). Supported versions that are affected are 12.1.1, 12.1.2, 12.1.3, 12.2.3, 12.2.4, 12.2.5 and 12.2.6. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle One-to-One Fulfillment. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle One-to-One Fulfillment, 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 One-to-One Fulfillment accessible data as well as unauthorized update, insert or delete access to some of Oracle One-to-One Fulfillment accessible data. CVSS v3.0 Base Score 8.2 (Confidentiality and Integrity impacts).

The vulnerability identified as CVE-2017-3427 resides within the Oracle One-to-One Fulfillment component of Oracle E-Business Suite, specifically within the User Interface subcomponent. This weakness affects multiple version releases including 12.1.1 through 12.2.6, representing a significant attack surface across the Oracle E-Business Suite ecosystem. The vulnerability classification as easily exploitable indicates that attackers can leverage this flaw without requiring specialized skills or extensive resources, making it particularly dangerous in production environments where such systems handle sensitive business data.
The technical nature of this vulnerability involves an insufficient authentication mechanism within the HTTP interface of the Oracle One-to-One Fulfillment component. This allows unauthenticated attackers to access the system through network connections using standard HTTP protocols. The vulnerability requires human interaction from users other than the attacker, suggesting that social engineering or targeted user manipulation may be necessary to achieve successful exploitation. The attack vector operates through the standard HTTP protocol, making it accessible to attackers who can reach the target network, and the vulnerability's impact extends beyond the immediate component to potentially affect related Oracle products within the suite.
The operational impact of this vulnerability is severe as it enables unauthorized access to critical data within the Oracle One-to-One Fulfillment system. Attackers can gain complete access to all accessible data within this component, along with unauthorized capabilities to update, insert, or delete information. The CVSS v3.0 base score of 8.2 reflects the high severity of this flaw, specifically highlighting the confidentiality and integrity impacts. This vulnerability falls under CWE-287 which addresses improper authentication issues, and aligns with ATT&CK technique T1190 for exploitation of remote services. The potential for data compromise and modification within the fulfillment processes represents a significant risk to business operations, particularly in supply chain management and customer order processing systems where data integrity is paramount.
Organizations affected by this vulnerability should implement immediate mitigation strategies including applying Oracle's security patches and updates, implementing network segmentation to limit access to the affected components, and establishing monitoring procedures to detect unauthorized access attempts. Network access controls should be strengthened to restrict HTTP access to authorized personnel only, while additional authentication mechanisms should be considered for critical system interfaces. The vulnerability's impact on multiple versions within the Oracle E-Business Suite requires comprehensive assessment across all affected systems to ensure complete remediation. Security teams should also consider implementing intrusion detection systems to monitor for suspicious HTTP traffic patterns that may indicate exploitation attempts, and conduct regular vulnerability assessments to identify similar weaknesses in the broader Oracle E-Business Suite environment.
