CVE-2021-2089 in iStore
Summary
by MITRE • 01/20/2021
Vulnerability in the Oracle iStore product of Oracle E-Business Suite (component: Runtime Catalog). 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-2021-2089 represents a critical security flaw within Oracle iStore, a component of the Oracle E-Business Suite ecosystem. This vulnerability exists in the Runtime Catalog functionality and affects specific version ranges including 12.1.1 through 12.1.3 and 12.2.3 through 12.2.10 of the Oracle E-Business Suite. The flaw manifests as an easily exploitable weakness that permits unauthenticated attackers to compromise the iStore system through HTTP network connections. The vulnerability classification aligns with CWE-284, which addresses improper access control issues, and demonstrates characteristics consistent with the ATT&CK technique T1078.004 related to valid accounts and credential access. The attack vector requires network access from an unauthenticated source, making it particularly dangerous for organizations with exposed web services.
The technical implementation of this vulnerability stems from inadequate access controls within the Runtime Catalog component, allowing unauthorized users to bypass authentication mechanisms and gain access to sensitive data within the Oracle iStore environment. The CVSS 3.1 scoring of 8.2 reflects the high severity of this flaw, with a base score indicating high confidentiality impact and low integrity impact. The vulnerability's configuration allows for unauthorized access to critical data and complete access to all Oracle iStore accessible data, while also permitting unauthorized update, insert, or delete operations on some accessible data. This represents a significant compromise of data integrity and confidentiality, with potential cascading effects across the broader Oracle E-Business Suite environment.
The operational impact of CVE-2021-2089 extends beyond the immediate iStore component to potentially affect additional Oracle products within the E-Business Suite ecosystem. Successful exploitation requires human interaction from individuals other than the attacker, suggesting that the vulnerability may be triggered through social engineering or user interaction with malicious content. However, the attack's success can result in substantial data breaches, including access to sensitive business information, financial data, and operational details that could compromise organizational security posture. The vulnerability's classification as a critical issue necessitates immediate attention and remediation efforts to prevent potential data exfiltration, financial loss, and operational disruption. Organizations utilizing affected Oracle E-Business Suite versions must implement immediate mitigation strategies to protect against exploitation attempts.
Recommended mitigations for this vulnerability include immediate patching of affected Oracle E-Business Suite versions to the latest security releases, implementation of network segmentation to limit access to iStore components, and deployment of web application firewalls to monitor and filter HTTP traffic. Security administrators should also conduct thorough network access reviews to ensure that only authorized personnel can access the affected systems. The vulnerability's characteristics align with ATT&CK technique T1190 for exploitation of remote services, emphasizing the need for proper access controls and network monitoring. Organizations should also implement comprehensive logging and monitoring solutions to detect potential exploitation attempts and maintain detailed audit trails for forensic analysis purposes.
