CVE-2021-2199 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-2021-2199 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 flaw exists within the Oracle iStore module which serves as a web-based storefront for enterprise customers, making it a prime target for cyber adversaries seeking unauthorized access to business-critical data. The vulnerability's classification as easily exploitable indicates that attackers can leverage relatively straightforward techniques to compromise the system without requiring specialized skills or extensive preparation. The security implications extend beyond the immediate iStore component as the attack vector can potentially impact additional Oracle products within the broader E-Business Suite environment, creating cascading security risks.
The technical nature of this vulnerability stems from insufficient authentication and authorization controls within the shopping cart functionality. Attackers can exploit this weakness through unauthenticated HTTP network access, eliminating the need for valid credentials or privileged accounts. The vulnerability requires human interaction from users other than the attacker, suggesting that social engineering or user manipulation may be necessary to initiate the attack vector. This characteristic aligns with the CVSS 3.1 scoring system which assigns a base score of 8.2, indicating high severity with significant impact on confidentiality and integrity. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) demonstrates that network-based exploitation is possible with low attack complexity, no privilege requirements, and requires user interaction, while the scope change (S:C) indicates that the vulnerability can affect additional products beyond the primary target. The impact assessment reveals that successful exploitation can result in unauthorized access to critical data, complete access to all Oracle iStore accessible data, and unauthorized modification capabilities including update, insert, and delete operations on sensitive information.
The operational impact of CVE-2021-2199 extends far beyond simple data theft, as it represents a potential gateway for more extensive system compromise within enterprise environments. Organizations utilizing affected Oracle E-Business Suite versions face significant risk of data breaches that could include customer information, financial records, proprietary business data, and other sensitive corporate assets. The vulnerability's ability to provide unauthorized update, insert, or delete access creates opportunities for data manipulation that could severely disrupt business operations and compromise regulatory compliance. The impact on confidentiality is rated as high (C:H) indicating that attackers can access critical data that organizations typically consider highly sensitive. The integrity impact rating of low (I:L) suggests that while attackers can modify data, the primary concern lies in unauthorized access to sensitive information rather than complete system compromise. Organizations may experience cascading effects as this vulnerability could potentially enable attackers to move laterally within their network infrastructure, particularly given that the E-Business Suite environment often integrates with other Oracle products and enterprise systems. The CVSS scoring system places this vulnerability in the high severity category, requiring immediate attention and remediation to prevent potential exploitation by threat actors.
Organizations should implement immediate mitigation strategies to address CVE-2021-2199, beginning with applying Oracle's official security patches and updates as released through their security bulletins. Network segmentation and access controls should be strengthened to limit exposure of the affected iStore components, particularly by restricting direct internet access to these systems. Monitoring and logging mechanisms should be enhanced to detect anomalous access patterns or unauthorized modifications to shopping cart data, which could indicate exploitation attempts. Security teams should conduct comprehensive vulnerability assessments to identify all instances of affected Oracle E-Business Suite versions within their environment and prioritize remediation efforts accordingly. The vulnerability's classification under CWE-287 (Improper Authentication) and its alignment with ATT&CK techniques such as T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS) highlights the need for layered defensive approaches. Regular security awareness training for personnel who interact with the iStore system can help reduce the risk of social engineering attacks that may be necessary to exploit this vulnerability. Additionally, organizations should consider implementing web application firewalls and intrusion detection systems specifically configured to monitor for exploitation attempts targeting this vulnerability, ensuring that any suspicious HTTP traffic directed toward affected iStore components is properly identified and blocked.
