CVE-2021-2185 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-2021-2185 represents a critical security flaw within Oracle iStore component of the Oracle E-Business Suite ecosystem. This vulnerability specifically resides in the Shopping Cart functionality and affects a broad range of Oracle E-Business Suite versions including 12.1.1 through 12.1.3 and 12.2.3 through 12.2.10. The flaw manifests as an easily exploitable weakness that can be leveraged by unauthenticated attackers who possess network access via HTTP protocols. The vulnerability's classification as easily exploitable indicates that attackers can readily develop and deploy attack vectors without requiring specialized tools or extensive technical expertise, making it particularly dangerous in production environments where such systems are often exposed to external networks.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the iStore shopping cart component. Attackers can exploit this weakness to gain unauthorized access to sensitive data within the Oracle iStore environment, potentially compromising complete access to all data accessible through the iStore interface. The vulnerability's impact extends beyond the immediate iStore component as successful exploitation can significantly affect additional Oracle products within the same suite, creating cascading security implications across the enterprise's business applications. The CVSS 3.1 score of 8.2 reflects the high severity of this flaw, with a base score indicating high confidentiality impact and low integrity impact, suggesting that attackers can access critical data without necessarily corrupting system integrity.
The operational impact of CVE-2021-2185 is substantial and multifaceted, potentially allowing attackers to perform unauthorized update, insert, or delete operations on data within the Oracle iStore accessible environment. This capability enables attackers to modify business-critical information, potentially affecting inventory management, customer data, order processing, and financial records. The requirement for human interaction from a person other than the attacker suggests that the vulnerability may be exploited through social engineering techniques or by leveraging legitimate user sessions, making detection more challenging. The vulnerability's vector specification CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C indicates network-based access with low attack complexity, no privilege requirements, and requires user interaction, while the scope change (S:C) demonstrates the potential for impact extending beyond the vulnerable component to affect other systems within the broader Oracle E-Business Suite environment.
Organizations affected by this vulnerability should prioritize immediate remediation through Oracle's official security patches and updates. The mitigation strategy should include implementing network segmentation to limit access to Oracle iStore components, deploying web application firewalls to monitor and filter HTTP traffic, and conducting comprehensive vulnerability assessments across all affected Oracle E-Business Suite installations. Security teams should also implement enhanced monitoring of user activities and system access logs to detect potential exploitation attempts. This vulnerability aligns with CWE-284 (Improper Access Control) and may be categorized under ATT&CK techniques related to privilege escalation and credential access. The attack surface expansion capability of this vulnerability makes it particularly concerning for enterprise environments where Oracle E-Business Suite components often integrate with other critical business systems, potentially creating pathways for lateral movement and broader system compromise. Organizations should also consider implementing additional security controls such as multi-factor authentication for administrative access and regular security audits to prevent unauthorized access to sensitive business data.
