CVE-2019-2666 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle One-to-One Fulfillment component of Oracle E-Business Suite (subcomponent: Print Server). Supported versions that are affected are 12.1.1 - 12.1.3 and 12.2.3 - 12.2.8. 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 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-2019-2666 resides within the Oracle One-to-One Fulfillment component of Oracle E-Business Suite, specifically within the Print Server subcomponent. This flaw affects a range of Oracle E-Business Suite versions including 12.1.1 through 12.1.3 and 12.2.3 through 12.2.8, representing a significant attack surface across multiple supported releases. The vulnerability classification as easily exploitable indicates that attackers can leverage this weakness with minimal technical sophistication, making it particularly dangerous in environments where network exposure is inevitable. The CVSS 3.0 score of 8.2 reflects the severity of the issue, with high confidentiality impact and low integrity impact, suggesting that unauthorized access to sensitive data represents the primary concern rather than data modification capabilities.
The technical nature of this vulnerability allows unauthenticated attackers to compromise the Oracle One-to-One Fulfillment system through HTTP network connections, eliminating the need for valid credentials or prior access. The requirement for human interaction from individuals other than the attacker indicates that social engineering or targeted phishing may be necessary to initiate exploitation, though the actual attack vector remains network-based and accessible via standard HTTP protocols. This characteristic places organizations at risk when their E-Business Suite components are exposed to untrusted networks or when proper network segmentation is not implemented. The vulnerability's potential to impact additional products beyond the immediate component demonstrates the interconnected nature of Oracle E-Business Suite implementations where a single weakness can cascade across multiple integrated systems.
The operational impact of successful exploitation can be severe, providing attackers with unauthorized access to critical data within the One-to-One Fulfillment system and potentially enabling complete access to all accessible data. Additionally, attackers may gain unauthorized update, insert, or delete capabilities for certain data within the system, creating both confidentiality and integrity risks. The CVSS vector analysis reveals that while the attack requires user interaction, the potential damage is significant enough to warrant immediate attention. The confidentiality impact rating of high (C:H) indicates that sensitive business information, including customer data, order details, and fulfillment records, could be accessed without authorization. The integrity impact rating of low (I:L) suggests that while modification capabilities exist, the primary concern remains data theft rather than systematic data corruption.
Organizations should implement immediate mitigations including network segmentation to isolate E-Business Suite components from untrusted networks, implementing proper access controls and authentication mechanisms, and applying Oracle's security patches as soon as they become available. The vulnerability aligns with CWE-287, which addresses authentication failures in software systems, and represents a critical gap in the security posture of Oracle E-Business Suite implementations. From an ATT&CK framework perspective, this vulnerability maps to techniques involving initial access through network services and privilege escalation through data access, with potential lateral movement opportunities if the compromised system has access to additional network resources. Organizations should conduct comprehensive security assessments to identify all instances of affected Oracle E-Business Suite versions and implement monitoring for suspicious HTTP traffic patterns that might indicate exploitation attempts.
