CVE-2017-3327 in E-Business
Summary
by MITRE
Vulnerability in the Oracle Common Applications component of Oracle E-Business Suite (subcomponent: Resources Module). 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-2017-3327 resides within the Oracle Common Applications component of Oracle E-Business Suite, specifically within the Resources Module subcomponent. This flaw represents a significant security weakness that affects multiple versions of the Oracle E-Business Suite including 12.1.1, 12.1.2, 12.1.3, 12.2.3, 12.2.4, 12.2.5, and 12.2.6. The vulnerability's classification as easily exploitable indicates that attackers can leverage this weakness with minimal technical sophistication, making it particularly dangerous in enterprise environments where Oracle E-Business Suite is widely deployed.
The technical nature of this vulnerability allows unauthenticated attackers to compromise Oracle Common Applications through network access using HTTP protocols. This means that malicious actors can exploit the flaw without requiring valid credentials or authentication tokens, significantly broadening the attack surface. The vulnerability's impact extends beyond just the targeted component as successful exploitation can affect additional Oracle products within the ecosystem, creating cascading security implications. The attack vector specifically leverages HTTP communication channels, which are commonly used for business applications and are often less strictly secured compared to other network protocols.
From an operational perspective, the vulnerability presents a severe risk to data confidentiality and integrity within Oracle Common Applications. The CVSS v3.0 base score of 8.2 indicates a high-severity threat that can result in unauthorized access to critical data repositories. Attackers can potentially gain complete access to all data accessible through Oracle Common Applications, along with unauthorized capabilities to update, insert, or delete information within these systems. This comprehensive access level means that the vulnerability could enable attackers to not only steal sensitive corporate information but also to modify business data, potentially causing significant financial and operational damage. The requirement for human interaction from individuals other than the attacker suggests that social engineering or targeted phishing might be necessary to trigger the vulnerability, though this does not mitigate the overall risk.
The vulnerability aligns with CWE-287 which addresses improper authentication issues, and its exploitation patterns correspond to techniques found in the ATT&CK framework under Initial Access and Credential Access phases. Organizations should implement immediate mitigations including applying Oracle's security patches, restricting HTTP access to critical systems, implementing network segmentation, and conducting thorough vulnerability assessments of their Oracle E-Business Suite deployments. Additionally, monitoring for suspicious HTTP traffic patterns and establishing robust access controls for the Resources Module can help detect and prevent exploitation attempts. The interconnected nature of Oracle E-Business Suite components means that addressing this vulnerability requires comprehensive security measures across the entire application stack rather than isolated component fixes.
