CVE-2017-3426 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-2017-3426 resides within the Oracle One-to-One Fulfillment component of Oracle E-Business Suite, specifically affecting the User Interface subcomponent. This weakness manifests in multiple supported versions including 12.1.1 through 12.2.6, creating a widespread exposure across the Oracle E-Business Suite ecosystem. The vulnerability's classification as easily exploitable indicates that attackers can leverage network-based HTTP connections without requiring authentication credentials, presenting a significant risk to organizations utilizing these Oracle applications. The attack vector requires only network access via standard HTTP protocols, making it particularly dangerous as it can be exploited from remote locations without physical or privileged access to the target systems.
The technical flaw represents a critical security weakness that enables unauthorized access to sensitive data within the Oracle One-to-One Fulfillment module. This vulnerability operates at the application layer and specifically targets the user interface component, which serves as the primary interaction point for users within the fulfillment process. Attackers can potentially gain complete access to all data accessible through the One-to-One Fulfillment functionality, including customer information, order details, inventory data, and other critical business information. The vulnerability's impact extends beyond the immediate module, as successful exploitation can affect additional Oracle products within the same ecosystem, creating cascading security implications throughout the enterprise's Oracle infrastructure. The CVSS v3.0 base score of 8.2 reflects the severity of potential confidentiality and integrity breaches, indicating a high-risk exposure that could lead to significant data compromise.
The operational impact of this vulnerability is substantial, as it allows attackers to perform unauthorized operations including data modification, insertion, and deletion within the affected Oracle One-to-One Fulfillment environment. This means that malicious actors could not only read sensitive information but also alter or destroy critical business data, potentially disrupting fulfillment processes and compromising business operations. The requirement for human interaction from a person other than the attacker suggests that social engineering or targeted phishing attacks may be employed to facilitate exploitation, making the vulnerability even more dangerous as it combines technical exploitation with human factors. Organizations utilizing these Oracle E-Business Suite versions face potential financial losses, regulatory compliance issues, and reputational damage from such security breaches. The vulnerability's presence in multiple versions indicates that organizations may have been exposed for extended periods without proper mitigation.
Organizations should implement immediate security measures to address this vulnerability, including applying Oracle's official security patches and updates as released through their vulnerability management processes. Network segmentation and access controls should be strengthened to limit exposure to only necessary personnel and systems. The vulnerability aligns with CWE-284 (Improper Access Control) and may relate to ATT&CK techniques involving credential access and privilege escalation. Regular security assessments and monitoring of Oracle E-Business Suite installations are essential to identify and remediate similar vulnerabilities. Additionally, organizations should conduct comprehensive vulnerability scans and penetration testing to ensure that all affected versions have been properly updated and that no other related vulnerabilities exist within their Oracle infrastructure. The remediation process should include thorough testing of patches in non-production environments before deployment to ensure operational stability and prevent disruption of critical business processes.
