CVE-2017-3326 in E-Business
Summary
by MITRE
Vulnerability in the Oracle Common Applications component of Oracle E-Business Suite (subcomponent: Role Summary). Supported versions that are affected are 12.1.1, 12.1.2, 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 Common Applications. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Common Applications, 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 Common Applications accessible data as well as unauthorized update, insert or delete access to some of Oracle Common Applications accessible data. CVSS v3.0 Base Score 8.2 (Confidentiality and Integrity impacts).

The vulnerability identified as CVE-2017-3326 resides within the Oracle Common Applications component of Oracle E-Business Suite, specifically affecting the Role Summary subcomponent. This security flaw impacts multiple version releases including 12.1.1 through 12.2.6, representing a significant attack surface across the Oracle E-Business Suite ecosystem. The vulnerability classification as easily exploitable indicates that attackers can leverage this weakness with minimal technical sophistication, making it particularly dangerous for organizations operating these systems. The CVSS v3.0 base score of 8.2 reflects the severity of potential impacts, with scores indicating high risk for both confidentiality and integrity violations.
The technical nature of this vulnerability allows unauthenticated attackers to compromise Oracle Common Applications through HTTP network access, eliminating the need for prior authentication credentials. This attack vector represents a critical weakness in the authentication framework of the E-Business Suite, where the system fails to properly validate incoming requests to the Role Summary functionality. The vulnerability requires human interaction from users other than the attacker, suggesting that social engineering or targeted phishing techniques may be employed to facilitate exploitation. This characteristic aligns with ATT&CK technique T1566 which involves social engineering to gain initial access to systems.
The operational impact of successful exploitation extends beyond the immediate compromise of Oracle Common Applications, potentially affecting additional products within the Oracle ecosystem. Attackers can achieve unauthorized access to critical data and gain complete access to all Oracle Common Applications accessible data, representing a severe breach of data confidentiality. Additionally, successful exploitation enables unauthorized update, insert, or delete operations on some Oracle Common Applications accessible data, creating potential for data integrity compromise and system manipulation. This dual impact on both confidentiality and integrity violates fundamental security principles and represents a significant risk to business operations and data protection.
Organizations affected by CVE-2017-3326 should implement immediate mitigation strategies focusing on network segmentation and access controls to limit exposure to this vulnerability. The vulnerability aligns with CWE-287 which addresses improper authentication issues in software systems, emphasizing the need for robust authentication mechanisms. Network-level protections including firewall rules and web application firewalls should be implemented to restrict access to the vulnerable Role Summary functionality. Regular security assessments and vulnerability scanning should be conducted to identify similar authentication weaknesses. Patch management procedures should be prioritized to ensure timely deployment of Oracle security patches addressing this specific vulnerability. The incident response plan should include procedures for monitoring and detecting unauthorized access attempts to Oracle E-Business Suite components. Organizations should also consider implementing additional authentication controls and monitoring mechanisms to detect potential exploitation attempts and mitigate the risk of data breaches.
