CVE-2021-2186 in iStore
Summary
by MITRE • 04/23/2021
Vulnerability in the Oracle iStore product of Oracle E-Business Suite (component: Shopping Cart). Supported versions that are affected are 12.1.1-12.1.3 and 12.2.3-12.2.10. 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 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2021-2186 represents a critical security flaw within Oracle iStore component of the Oracle E-Business Suite ecosystem. This vulnerability specifically affects the shopping cart functionality and impacts multiple version ranges including 12.1.1 through 12.1.3 and 12.2.3 through 12.2.10. The vulnerability classification as easily exploitable indicates that attackers can leverage this weakness without requiring specialized tools or extensive technical knowledge, making it particularly dangerous in production environments. The CVSS 3.1 scoring of 8.2 reflects the severity of the potential impact, with high confidentiality impact and low integrity impact, suggesting that unauthorized access to sensitive data poses the primary risk.
The technical nature of this vulnerability stems from insufficient authentication mechanisms within the Oracle iStore shopping cart component, allowing unauthenticated attackers to access sensitive data through HTTP network connections. This weakness creates a pathway for attackers to potentially compromise the entire Oracle iStore system, which serves as a critical e-commerce component within enterprise environments. The requirement for human interaction from users other than the attacker suggests that social engineering or targeted phishing attacks may be necessary to initially compromise the system, though once the initial access is gained, the vulnerability can be exploited continuously. The attack vector operates through standard HTTP protocols, making it particularly challenging to detect and prevent since it appears as legitimate web traffic.
The operational impact of this vulnerability extends beyond the immediate Oracle iStore component, potentially affecting additional Oracle products within the E-Business Suite environment. Successful exploitation can result in unauthorized access to critical business data, including customer information, transaction records, and other sensitive corporate data. The vulnerability's ability to provide complete access to all Oracle iStore accessible data represents a severe threat to data confidentiality and integrity. Additionally, attackers can gain unauthorized update, insert, or delete access to specific data within the system, creating potential for data manipulation and corruption that could significantly impact business operations and regulatory compliance. The CVSS vector indicates that while the attack requires user interaction, the scope of impact is considered "changed," suggesting that the vulnerability can affect additional products beyond the primary target.
Organizations affected by CVE-2021-2186 should implement immediate mitigation strategies including applying Oracle's security patches and updates as soon as they become available. Network segmentation and monitoring should be enhanced to detect anomalous HTTP traffic patterns that may indicate exploitation attempts. Access controls should be reviewed and strengthened to ensure that only authorized users can access sensitive data and functionality within the Oracle iStore environment. The vulnerability aligns with CWE-287, which addresses improper authentication issues, and represents a significant concern from an ATT&CK framework perspective under the T1190 technique for Exploit Public-Facing Application. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other Oracle components and ensure comprehensive protection against similar attack vectors.
