CVE-2017-3349 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle Marketing 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 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 v3.0 Base Score 8.2 (Confidentiality and Integrity impacts).

The vulnerability identified as CVE-2017-3349 represents a critical security flaw within Oracle E-Business Suite's Marketing component, specifically within the User Interface subcomponent. This vulnerability affects multiple version releases including 12.1.1 through 12.2.6, indicating a widespread impact across the Oracle E-Business Suite product line. The flaw resides in the way the system handles HTTP requests, creating an attack surface that can be exploited by unauthenticated network-based adversaries without requiring any prior authentication credentials or privileged access. The vulnerability's classification as easily exploitable means that attackers can leverage standard network reconnaissance and exploitation techniques to target affected systems, making it particularly dangerous in production environments where such systems are often exposed to external networks.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the Oracle Marketing User Interface component. Attackers can craft malicious HTTP requests that bypass normal authentication and authorization checks, allowing them to gain unauthorized access to sensitive marketing data. This flaw operates at the application layer and can be exploited through standard web protocols, making it accessible to threat actors with basic network connectivity and minimal technical expertise. The vulnerability's impact extends beyond the immediate Marketing component as it can potentially affect other integrated Oracle products within the same suite, creating a cascading effect that could compromise entire enterprise systems. The CVSS v3.0 base score of 8.2 reflects the severity of both confidentiality and integrity impacts, indicating that successful exploitation could lead to complete data compromise and unauthorized modifications to critical business information.
From an operational perspective, this vulnerability poses significant risks to organizations relying on Oracle E-Business Suite for their marketing operations and enterprise resource planning. The requirement for human interaction from users other than the attacker suggests that social engineering or targeted phishing campaigns might be necessary to initially trigger the vulnerability, though once activated, the attack can proceed without further user involvement. The potential for unauthorized access to critical marketing data includes customer information, campaign details, and business intelligence that could be valuable to competitors or malicious actors. Additionally, the ability to perform unauthorized updates, inserts, or deletions creates opportunities for data corruption, manipulation, or complete data loss that could severely impact business operations and regulatory compliance. Organizations may face substantial financial and reputational damage if this vulnerability is exploited successfully, particularly in industries where marketing data integrity is critical to business operations.
Organizations should implement immediate mitigations including applying the relevant Oracle security patches and updates released to address this vulnerability. Network segmentation and access controls should be strengthened to limit exposure of affected systems to untrusted networks, while monitoring and logging mechanisms should be enhanced to detect potential exploitation attempts. Security teams should conduct thorough vulnerability assessments to identify all instances of affected Oracle E-Business Suite installations and prioritize remediation efforts based on risk exposure. The vulnerability aligns with CWE-284 (Improper Access Control) and represents a clear violation of the principle of least privilege, where system components should only be accessible to authorized users with appropriate permissions. From an ATT&CK framework perspective, this vulnerability maps to techniques involving initial access through network service exploitation and privilege escalation through data manipulation, highlighting the need for comprehensive defensive measures that address both network-level protections and application-level security controls.
