CVE-2017-3440 in Customer Interaction History
Summary
by MITRE
Vulnerability in the Oracle Customer Interaction History 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 Customer Interaction History. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Customer Interaction History, 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 Customer Interaction History accessible data as well as unauthorized update, insert or delete access to some of Oracle Customer Interaction History accessible data. CVSS v3.0 Base Score 8.2 (Confidentiality and Integrity impacts).

The vulnerability identified as CVE-2017-3440 resides within the Oracle Customer Interaction History component of Oracle E-Business Suite, specifically within the User Interface subcomponent. This flaw affects Oracle E-Business Suite versions 12.1.1, 12.1.2, and 12.1.3, representing a critical 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 with significant impacts to both confidentiality and integrity, reflecting the potential for unauthorized access to sensitive customer interaction data and the ability to modify or delete critical information within the affected system.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the User Interface component of Oracle Customer Interaction History. Attackers can leverage this weakness to gain unauthorized access to critical data stored within the customer interaction history database, potentially accessing comprehensive records of customer interactions, communications, and related business information. The vulnerability's design flaw allows for complete access to all accessible data within the Customer Interaction History module, while also enabling unauthorized update, insert, or delete operations on selected data sets. This represents a fundamental breakdown in the principle of least privilege and demonstrates inadequate separation of concerns within the application's security architecture. The vulnerability's classification under CWE 284 (Improper Access Control) aligns with the observed behavior of allowing unauthorized data access and modification operations.
The operational impact of this vulnerability extends beyond the immediate Customer Interaction History component, as successful exploitation can significantly affect additional Oracle E-Business Suite products that may share underlying infrastructure or data repositories. The requirement for human interaction from a person other than the attacker suggests that social engineering or targeted phishing attacks might be employed to facilitate exploitation, though the core vulnerability itself remains accessible to network-based attacks. This characteristic places organizations at risk of data breaches that could compromise sensitive customer information, business communications, and interaction records that form the foundation of customer relationship management within enterprise environments. The potential for unauthorized modification of customer interaction data could lead to data integrity issues, while complete access to the data repository could result in substantial information disclosure.
Organizations affected by CVE-2017-3440 should implement immediate mitigations including applying the relevant Oracle security patches and updates, implementing network segmentation to limit access to Oracle E-Business Suite components, and strengthening access controls through proper authentication mechanisms. The vulnerability's classification under ATT&CK technique T1190 (Exploit Public-Facing Application) indicates that attackers would likely leverage this weakness as part of broader attack campaigns targeting enterprise applications. Additional defensive measures should include monitoring network traffic for suspicious HTTP requests, implementing intrusion detection systems to identify exploitation attempts, and conducting regular security assessments of Oracle E-Business Suite deployments. Organizations should also consider implementing application firewalls and restricting direct internet access to Oracle application servers to minimize exposure windows and reduce the attack surface for this specific vulnerability.
