CVE-2017-3557 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 12.1.3, 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 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-2017-3557 resides within the Oracle One-to-One Fulfillment component of Oracle E-Business Suite, specifically within the Print Server subcomponent. This security flaw affects multiple supported versions including 12.1.3, 12.2.3, 12.2.4, 12.2.5, and 12.2.6, representing a significant attack surface for malicious actors targeting enterprise resource planning systems. The vulnerability's classification as easily exploitable indicates that attackers can leverage relatively straightforward techniques to compromise the affected systems, making it particularly dangerous in production environments where such systems often handle sensitive business data.
The technical nature of this vulnerability stems from insufficient input validation within the Print Server functionality, which allows remote attackers to manipulate HTTP requests and potentially execute unauthorized operations. The CVSS 3.0 score of 8.2 reflects the severity of impact, with a high confidentiality impact score indicating that successful exploitation could lead to unauthorized access to critical data within the Oracle One-to-One Fulfillment module. The integrity impact score of low suggests that while data modification may occur, the primary concern lies in data confidentiality and access rather than complete system integrity compromise. The vulnerability requires network access via HTTP and can be exploited by unauthenticated attackers, eliminating the need for prior credentials or privileged access.
The operational impact of CVE-2017-3557 extends beyond the immediate Oracle One-to-One Fulfillment component, as successful attacks can significantly affect additional products within the Oracle E-Business Suite ecosystem. This cascading effect demonstrates the interconnected nature of enterprise applications and highlights the importance of comprehensive security assessments across entire application suites rather than isolated components. The requirement for human interaction from a person other than the attacker suggests that the vulnerability may be exploited through social engineering or user interaction scenarios, potentially involving phishing attacks or other manipulation techniques that trick legitimate users into triggering malicious requests.
Organizations affected by this vulnerability face substantial risk of data breaches and unauthorized access to sensitive business information, including customer data, financial records, and operational details that could be exploited for competitive advantage or financial gain. The potential for unauthorized update, insert, or delete operations against Oracle One-to-One Fulfillment accessible data represents a particularly concerning aspect of this vulnerability, as it could lead to data corruption or manipulation that might go undetected for extended periods. Security professionals should note that this vulnerability aligns with CWE-20 (Improper Input Validation) and may map to ATT&CK techniques involving initial access through web application attacks and credential access through data manipulation. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) indicates that network-based attacks are possible with low complexity, no prior privileges required, and that user interaction is necessary for successful exploitation, though the scope can extend beyond the immediate component to affect additional products within the suite.
Mitigation strategies for CVE-2017-3557 should include immediate implementation of Oracle security patches and updates, network segmentation to limit access to affected systems, and enhanced monitoring of HTTP traffic for suspicious activities. Organizations should also implement comprehensive access controls and user authentication mechanisms to reduce the risk of exploitation through social engineering or user interaction scenarios. Regular security assessments and vulnerability scanning should be conducted to identify and remediate similar weaknesses in the broader Oracle E-Business Suite environment, ensuring that security measures are not limited to addressing individual vulnerabilities but instead provide comprehensive protection against similar attack vectors. The vulnerability serves as a reminder of the critical importance of maintaining up-to-date security patches and implementing defense-in-depth strategies to protect enterprise applications from exploitation.
