CVE-2021-2183 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-2021-2183 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 resides in the Oracle iStore module which serves as an e-commerce platform component within the broader Oracle E-Business Suite architecture. The vulnerability's classification as easily exploitable indicates that attackers can leverage this weakness with minimal technical sophistication, making it particularly dangerous in production environments where such systems handle sensitive business data and customer information.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the shopping cart functionality. Attackers can exploit this weakness through unauthenticated HTTP network access, bypassing traditional authentication requirements that would normally protect sensitive data within the iStore environment. The CVSS 3.1 scoring of 8.2 reflects the severity of the potential impact, with a high confidentiality impact score indicating that successful exploitation could lead to unauthorized access to critical data and complete access to all Oracle iStore accessible data. The integrity impact score of 8.2 further demonstrates that attackers could potentially modify or delete data within the system, while the availability impact remains low at 0.0 as the vulnerability primarily affects data access rather than system availability.
The operational impact of CVE-2021-2183 extends beyond the immediate iStore component to potentially affect other connected Oracle E-Business Suite products within the same environment. This cascading effect occurs because the vulnerability exists within a core component that interfaces with other modules within the Oracle suite, creating opportunities for attackers to leverage the initial compromise to access additional systems and data. The requirement for human interaction from a person other than the attacker suggests that the exploitation may involve social engineering elements or targeted attacks that require some form of user engagement, though the underlying vulnerability itself remains easily accessible to unauthorized parties. The CVSS vector indicates network-based attack potential with low access complexity and no privilege requirements, making this vulnerability particularly dangerous in environments where network access to Oracle applications is not properly restricted.
Organizations affected by this vulnerability should prioritize immediate remediation through Oracle's security patches and updates, as the vulnerability's classification as easily exploitable suggests that it is likely already being targeted by threat actors. The attack surface extends to any environment running affected Oracle E-Business Suite versions, particularly those with exposed HTTP endpoints that are accessible to external networks. Security teams should implement network segmentation to limit access to Oracle application servers, deploy web application firewalls to monitor and filter HTTP traffic, and conduct comprehensive vulnerability assessments to identify other potential entry points within their Oracle E-Business Suite environments. The vulnerability's characteristics align with CWE-284 (Improper Access Control) and may also relate to CWE-352 (Cross-Site Request Forgery) depending on the specific exploitation vectors. From an ATT&CK framework perspective, this vulnerability maps to techniques involving initial access through network service exploitation and privilege escalation through data access and modification, potentially leading to lateral movement within the Oracle ecosystem and broader enterprise networks. Organizations should also consider implementing additional monitoring controls to detect unusual access patterns and unauthorized data modifications that could indicate exploitation attempts, given the potential for both data exfiltration and data integrity compromise.
