CVE-2019-2583 in iSupplier Portal
Summary
by MITRE
Vulnerability in the Oracle iSupplier Portal component of Oracle E-Business Suite (subcomponent: Attachments). Supported versions that are affected are 12.1.3, 12.2.3, 12.2.4, 12.2.5, 12.2.6, 12.2.7 and 12.2.8. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle iSupplier Portal. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle iSupplier Portal, 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 iSupplier Portal accessible data as well as unauthorized update, insert or delete access to some of Oracle iSupplier Portal accessible data. CVSS 3.0 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2019-2583 affects the Oracle iSupplier Portal component within Oracle E-Business Suite, specifically within the Attachments subcomponent. This security flaw exists in multiple supported versions including 12.1.3, 12.2.3, 12.2.4, 12.2.5, 12.2.6, 12.2.7, and 12.2.8, making it a widespread concern across various Oracle EBS deployments. The vulnerability's classification as easily exploitable indicates that attackers can leverage it without requiring specialized skills or tools, significantly increasing the risk to organizations utilizing these systems. The attack vector operates through HTTP network access, meaning that an unauthenticated attacker can potentially compromise the system simply by connecting to the portal over the network.
The technical nature of this vulnerability stems from insufficient access controls within the iSupplier Portal's attachment handling functionality. While the vulnerability resides specifically within the iSupplier Portal component, its impact extends beyond this single application due to the integrated nature of Oracle E-Business Suite environments. The security implications are particularly concerning because successful exploitation can lead to unauthorized access to critical data within the portal, potentially allowing attackers to view sensitive supplier information, purchase orders, and other confidential business data. Additionally, the vulnerability enables unauthorized modification capabilities, allowing attackers to insert, update, or delete data within the portal's accessible data stores, creating both confidentiality and integrity risks.
The operational impact of CVE-2019-2583 is substantial given its CVSS 3.0 base score of 8.2, which indicates a high severity level. The vulnerability's classification as having low attack complexity and no required privileges makes it particularly dangerous as it can be exploited by attackers without authentication. The requirement for human interaction from a person other than the attacker suggests that social engineering or targeted user engagement may be necessary for exploitation, though this does not mitigate the overall risk. The potential for significant impact on additional products aligns with the supply chain attack model described in the MITRE ATT&CK framework under the T1190 technique for Exploit Public-Facing Application. Organizations may face data breaches, financial losses, and regulatory compliance issues if this vulnerability is exploited, particularly in supply chain environments where sensitive supplier information is processed.
The vulnerability's impact on data confidentiality and integrity, as reflected in the CVSS vector, demonstrates that attackers can achieve high confidentiality impact while maintaining moderate integrity impact. This suggests that while the primary concern is unauthorized data access, the potential for data modification exists as well. Organizations should consider implementing network segmentation and access controls to limit exposure to this vulnerability, particularly given that the attack requires only network access via HTTP. The vulnerability's presence in multiple versions of Oracle E-Business Suite indicates that organizations should prioritize patch management and ensure all affected systems are updated to mitigate this risk. Security teams should also implement monitoring for unusual access patterns and unauthorized data modifications, as the vulnerability's impact extends across multiple Oracle EBS products and could affect the broader enterprise security posture. This vulnerability aligns with CWE-284, which describes improper access control issues, and represents a clear example of how insufficient authorization controls can lead to significant security breaches in enterprise applications.
