CVE-2017-3279 in Leads Management
Summary
by MITRE
Vulnerability in the Oracle Leads Management component of Oracle E-Business Suite (subcomponent: User Interface). Supported versions that are affected are 12.1.1, 12.1.2 and 12.1.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Leads Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Leads Management, 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 Leads Management accessible data as well as unauthorized update, insert or delete access to some of Oracle Leads Management accessible data. CVSS v3.0 Base Score 8.2 (Confidentiality and Integrity impacts).

The vulnerability identified as CVE-2017-3279 resides within the Oracle Leads Management component of Oracle E-Business Suite, specifically affecting the User Interface subcomponent. This flaw manifests in versions 12.1.1, 12.1.2, and 12.1.3, representing a significant security weakness that can be exploited by unauthenticated attackers. The vulnerability operates through HTTP network access, making it particularly dangerous as it requires no prior authentication credentials to initiate exploitation attempts. The CVSS v3.0 base score of 8.2 indicates a high-severity threat that impacts both confidentiality and integrity aspects of the affected systems.
The technical nature of this vulnerability stems from insufficient input validation within the Oracle Leads Management interface, allowing attackers to manipulate HTTP requests and potentially execute unauthorized operations. This flaw enables attackers to gain unauthorized access to critical data within the leads management system and may also permit unauthorized modification of data through update, insert, or delete operations. The vulnerability's exploitation requires human interaction from users other than the attacker, suggesting that social engineering or user manipulation might be necessary components of successful attacks. However, the core technical weakness remains in the application's failure to properly validate and sanitize user inputs within the leads management interface.
The operational impact of CVE-2017-3279 extends beyond the immediate leads management system, as successful exploitation can significantly affect additional products within the Oracle E-Business Suite ecosystem. This cascading effect means that compromise of one component can potentially lead to broader system infiltration and data breaches across interconnected applications. Organizations utilizing affected versions face substantial risk of data exfiltration, unauthorized data modification, and potential business disruption. The vulnerability's classification under CWE-20 (Improper Input Validation) and its alignment with ATT&CK technique T1190 (Exploit Public-Facing Application) highlights the fundamental security gap in input sanitization processes. The attack surface is particularly concerning given that Oracle E-Business Suite applications typically contain sensitive business data including customer information, sales leads, and proprietary business intelligence that organizations rely upon for competitive advantage.
Organizations should prioritize immediate mitigation strategies including applying Oracle's security patches and updates for the affected versions, implementing network segmentation to limit access to the vulnerable components, and deploying web application firewalls to monitor and filter HTTP requests. Additional protective measures involve restricting network access to the vulnerable applications, conducting thorough vulnerability assessments, and establishing monitoring protocols to detect anomalous access patterns. The vulnerability demonstrates the critical importance of maintaining current security patches and implementing robust input validation controls throughout enterprise applications. Organizations should also consider implementing principle of least privilege access controls and regular security audits to prevent similar vulnerabilities from being exploited in other components of their Oracle E-Business Suite deployments.
