CVE-2018-3011 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle Trade Management component of Oracle E-Business Suite (subcomponent: User Interface). Supported versions that are affected are 12.1.1, 12.1.2, 12.1.3, 12.2.3, 12.2.4, 12.2.5, 12.2.6 and 12.2.7. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Trade Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Trade 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 Trade Management accessible data as well as unauthorized update, insert or delete access to some of Oracle Trade Management accessible data. CVSS 3.0 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2018-3011 represents a critical security flaw within Oracle Trade Management component of the Oracle E-Business Suite, specifically affecting the User Interface subcomponent. This vulnerability manifests as a buffer overflow condition that occurs when processing HTTP requests, making it particularly dangerous due to its ease of exploitation and the lack of authentication requirements. The affected versions span multiple release lines including 12.1.1 through 12.2.7, indicating a widespread impact across the Oracle E-Business Suite ecosystem. The vulnerability's classification as easily exploitable means that attackers can leverage it without requiring specialized tools or extensive technical knowledge, making it particularly attractive to threat actors seeking to compromise enterprise systems.
The technical implementation of this vulnerability stems from inadequate input validation within the Oracle Trade Management User Interface, where HTTP requests containing malformed data can trigger buffer overflow conditions. This flaw operates at the application layer and requires only network access via HTTP to exploit, eliminating the need for prior authentication or privileged access. The vulnerability's design allows for a specific type of attack vector where an unauthenticated attacker can send specially crafted HTTP requests to the affected Oracle E-Business Suite instances. The buffer overflow condition creates opportunities for arbitrary code execution or data manipulation, depending on how the vulnerability is leveraged by attackers. The flaw's impact extends beyond the immediate Trade Management component, as the attack can potentially affect additional Oracle products within the same suite due to shared architectural elements and common data access mechanisms.
From an operational perspective, the vulnerability presents significant risk to organizations utilizing Oracle E-Business Suite, as successful exploitation can lead to unauthorized access to critical business data including financial records, customer information, and trade management data. The CVSS 3.0 score of 8.2 reflects the high severity of this vulnerability, with confidentiality impact rated as high and integrity impact as low, indicating that attackers can potentially read sensitive data without being detected. The requirement for human interaction suggests that while the attack itself can be automated, it may still require some form of social engineering or user involvement to achieve full exploitation. The potential for unauthorized update, insert, or delete operations adds another dimension of risk, as attackers could modify business data to cause financial losses or operational disruptions. Organizations may experience cascading effects where compromise of one component leads to broader system infiltration due to shared database connections and common user access controls.
The mitigation strategies for CVE-2018-3011 should prioritize immediate patch application from Oracle, as this represents the most effective defense against the vulnerability. Organizations should also implement network-level controls such as firewalls and access control lists to restrict access to Oracle E-Business Suite components from untrusted networks. The principle of least privilege should be enforced by limiting user access rights to only those functions necessary for business operations, reducing the potential impact of successful exploitation. Monitoring and logging mechanisms should be enhanced to detect unusual HTTP request patterns or unauthorized access attempts that could indicate exploitation attempts. Security teams should also consider implementing network segmentation to isolate Oracle E-Business Suite environments from critical business systems, as recommended by the CWE-119 standard for buffer overflow prevention. Additionally, regular vulnerability assessments and penetration testing should be conducted to identify and remediate similar issues before they can be exploited by threat actors, aligning with ATT&CK framework tactics related to initial access and execution phases. The vulnerability's classification as a remote code execution flaw makes it particularly important to maintain up-to-date security patches and implement comprehensive security monitoring solutions across all Oracle E-Business Suite installations.
