CVE-2017-3528 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle Applications Framework component of Oracle E-Business Suite (subcomponent: Popup windows (lists of values, datepicker, etc.)). 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 Applications Framework. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Applications Framework, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Applications Framework accessible data. CVSS 3.0 Base Score 4.7 (Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N).

The vulnerability identified as CVE-2017-3528 resides within the Oracle Applications Framework component of Oracle E-Business Suite, specifically affecting popup windows functionality including lists of values and datepicker interfaces. This weakness manifests in multiple supported versions including 12.1.3, 12.2.3, 12.2.4, 12.2.5, and 12.2.6, creating a significant security risk for organizations utilizing these systems. The vulnerability operates through the HTTP protocol and requires network access from an unauthenticated attacker, making it particularly dangerous as it can be exploited without prior authentication credentials. The CVSS 3.0 scoring system rates this vulnerability with a base score of 4.7, indicating a moderate severity level with integrity impacts specifically. The attack vector requires network access from a remote location, has low attack complexity, and necessitates user interaction from someone other than the attacker, which aligns with the CVSS vector assessment of AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N.
The technical flaw within the Oracle Applications Framework stems from improper validation of user input within popup window functionalities, particularly when handling data from external sources or user interactions. This vulnerability represents a classic case of insufficient input validation that could allow malicious actors to manipulate the framework's behavior through crafted HTTP requests. The implementation of popup windows for lists of values and datepickers creates an attack surface where unvalidated data can be injected into the system's processing pipeline. The vulnerability's classification under CWE (Common Weakness Enumeration) would likely fall under CWE-20 for "Improper Input Validation" or potentially CWE-79 for "Cross-site Scripting" depending on the specific exploitation method. Attackers can leverage this weakness to achieve unauthorized update, insert, or delete operations on data accessible through the Oracle Applications Framework, though the attack requires human interaction to succeed, typically involving a user clicking on maliciously crafted links or interacting with manipulated popup windows.
The operational impact of this vulnerability extends beyond the immediate Oracle Applications Framework component and can significantly affect other integrated products within the Oracle E-Business Suite ecosystem. Organizations that have deployed these vulnerable versions face potential data integrity compromises where unauthorized modifications could occur to critical business data. The vulnerability's ability to enable unauthorized data modification creates risks for financial systems, inventory management, and other business-critical processes that rely on the integrity of the Oracle E-Business Suite. The CVSS scoring indicates that while the attack requires user interaction, the potential for data manipulation remains substantial, particularly when considering that the vulnerability affects core framework components that support numerous business applications within the suite. This cascading impact means that successful exploitation can compromise not just individual modules but entire business processes that depend on the affected framework components.
Organizations should implement immediate mitigations including applying the relevant Oracle patches and security updates released for this vulnerability, as well as implementing network-level controls to restrict access to Oracle E-Business Suite applications. The implementation of web application firewalls and intrusion detection systems can help monitor for suspicious HTTP traffic patterns that may indicate exploitation attempts. Additionally, organizations should conduct comprehensive security assessments to identify all instances of the vulnerable versions and ensure proper access controls are implemented. The ATT&CK framework would classify this vulnerability under techniques related to privilege escalation and data manipulation, specifically targeting the application layer and potentially leveraging social engineering techniques to achieve successful exploitation through user interaction. Network segmentation and principle of least privilege access controls should be implemented to minimize the potential impact of any successful exploitation attempts, while regular security monitoring and vulnerability scanning should be maintained to detect and respond to similar threats in the environment.
