CVE-2018-3190 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle E-Business Intelligence component of Oracle E-Business Suite (subcomponent: Overview Page/Report Rendering). 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 E-Business Intelligence. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle E-Business Intelligence, 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 E-Business Intelligence accessible data as well as unauthorized update, insert or delete access to some of Oracle E-Business Intelligence 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-2018-3190 resides within Oracle E-Business Intelligence component of the Oracle E-Business Suite, specifically affecting the Overview Page/Report Rendering subcomponent. This security flaw impacts versions 12.1.1, 12.1.2, and 12.1.3 of the suite, representing a critical weakness that can be exploited by unauthenticated attackers through HTTP network connections. The vulnerability's classification as easily exploitable indicates that attackers require minimal technical expertise to leverage this weakness, making it particularly dangerous in production environments where such systems are often accessible over networks.
The technical nature of this vulnerability stems from insufficient input validation within the report rendering functionality, which allows maliciously crafted HTTP requests to bypass authentication mechanisms and gain unauthorized access to sensitive business intelligence data. The CVSS 3.0 score of 8.2 reflects the high severity of this flaw, with a base score that indicates significant impact across confidentiality and integrity domains. The attack vector requires network access via HTTP, meaning that any system hosting the affected Oracle E-Business Intelligence component could potentially be compromised simply by exposing it to external network traffic without proper security controls.
The operational impact of this vulnerability extends beyond the immediate compromise of Oracle E-Business Intelligence data, as successful exploitation can result in unauthorized access to critical business information and potentially enable attackers to modify or delete sensitive data within the system. 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 unauthenticated network access. This characteristic aligns with ATT&CK technique T1190 for exploitation of remote services and may involve CWE-20 for improper input validation or CWE-287 for inadequate authentication mechanisms.
Organizations affected by CVE-2018-3190 should implement immediate mitigations including applying the relevant Oracle security patches, implementing network segmentation to limit access to the affected components, and deploying web application firewalls to monitor and filter malicious HTTP requests. The vulnerability's potential to impact additional products within the Oracle E-Business Suite ecosystem means that comprehensive security assessments should be conducted across the entire suite to identify any related weaknesses. Security monitoring should focus on unusual access patterns, unauthorized data modifications, and any attempts to access sensitive reports or dashboards that might indicate exploitation attempts. The CVSS vector indicates that while no user interaction is required for the initial exploitation, the attack could significantly impact additional products, making it essential for organizations to maintain comprehensive visibility across their entire Oracle deployment landscape.
