CVE-2018-3018 in iStore
Summary
by MITRE
Vulnerability in the Oracle iStore component of Oracle E-Business Suite (subcomponent: Shopping Cart). 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 iStore. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle iStore, 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 iStore accessible data as well as unauthorized update, insert or delete access to some of Oracle iStore 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-2018-3018 resides within the Oracle iStore component of Oracle E-Business Suite, specifically within the Shopping Cart subcomponent. This weakness represents a critical security flaw that affects multiple versions of the Oracle E-Business Suite including 12.1.1 through 12.2.7, making it a widespread concern across various organizational deployments. The vulnerability operates at the application layer and manifests as an insufficient authorization mechanism that permits unauthorized access to sensitive data and operations within the iStore environment.
The technical implementation of this vulnerability stems from inadequate validation of user privileges and session management within the shopping cart functionality. Attackers can exploit this weakness by sending specifically crafted HTTP requests to the vulnerable Oracle iStore component without requiring any authentication credentials. The vulnerability's classification as easily exploitable indicates that the attack vector requires minimal technical expertise and can be executed through standard network-based means. The CVSS 3.0 score of 8.2 reflects the severity of the potential impact, with high confidentiality impact and low integrity impact, demonstrating that unauthorized access to critical data poses the primary risk.
The operational impact of this vulnerability extends beyond the immediate iStore component, as it can affect additional Oracle products within the E-Business Suite ecosystem. Successful exploitation enables attackers to gain complete access to all Oracle iStore accessible data, including customer information, order details, and potentially sensitive business data. The vulnerability also permits unauthorized modification of data through update, insert, or delete operations on certain accessible data elements. This capability creates significant risk for organizations relying on Oracle E-Business Suite for their commerce operations, as it could lead to data breaches, financial loss, and operational disruption.
The requirement for human interaction from a person other than the attacker indicates that while the vulnerability can be exploited remotely, it likely requires some form of social engineering or user participation in the attack process. This characteristic places the vulnerability in the context of the MITRE ATT&CK framework under the 'Initial Access' and 'Persistence' phases, where network-based attacks can be combined with user interaction to achieve more persistent access. Organizations should consider implementing network segmentation and monitoring to detect unusual traffic patterns that might indicate exploitation attempts. The vulnerability aligns with CWE-285, which addresses insufficient authorization issues, and represents a classic example of how inadequate access controls can compromise entire application ecosystems.
Mitigation strategies should include immediate application of Oracle's security patches and updates, network-based access controls to restrict access to the iStore component, and comprehensive monitoring of access logs for suspicious activities. Organizations should also implement proper network segmentation to limit the attack surface and consider disabling unnecessary features or components. The vulnerability's classification under CVSS vector AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N indicates that network-level protection measures such as firewalls and intrusion detection systems should be deployed to prevent unauthorized access attempts. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other Oracle E-Business Suite components that may present similar risks to organizational security posture.
