CVE-2020-2843 in iSupport
Summary
by MITRE
Vulnerability in the Oracle iSupport product of Oracle E-Business Suite (component: Profile). Supported versions that are affected are 12.1.1-12.1.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle iSupport. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle iSupport, 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 iSupport accessible data as well as unauthorized update, insert or delete access to some of Oracle iSupport 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-2020-2843 resides within Oracle iSupport, a component of the Oracle E-Business Suite ecosystem, specifically targeting the Profile functionality. This weakness affects Oracle E-Business Suite versions 12.1.1 through 12.1.3, representing a significant security gap in enterprise resource planning systems that organizations rely upon for critical business operations. The vulnerability's classification as easily exploitable indicates that attackers can leverage network-based HTTP access to compromise the system without requiring authentication credentials, making it particularly dangerous in environments where network exposure is common.
The technical flaw manifests as a lack of proper authentication mechanisms within the Oracle iSupport profile component, allowing unauthorized access to sensitive data and operations. This vulnerability operates under the Common Weakness Enumeration framework as a weakness related to insufficient authentication, specifically categorized under CWE-287 which addresses improper authentication. The attack vector requires network access via HTTP protocol, enabling remote exploitation without the need for prior system compromise or specialized access rights. The CVSS 3.0 scoring of 8.2 reflects the severity of impact, with high confidentiality implications and low integrity impact, indicating that successful exploitation could lead to unauthorized access to critical data while potentially allowing modifications to system data.
The operational impact of this vulnerability extends beyond the immediate Oracle iSupport component, as the attack can significantly affect additional Oracle products within the E-Business Suite environment. This cascading effect demonstrates the interconnected nature of enterprise applications where a single vulnerability can compromise entire application ecosystems. Attackers exploiting this weakness can achieve complete access to all Oracle iSupport accessible data, including sensitive financial information, customer data, and operational records. Additionally, the vulnerability permits unauthorized update, insert, or delete operations against specific Oracle iSupport accessible data, creating potential for data corruption, manipulation, and loss of data integrity. The requirement for human interaction from individuals other than the attacker suggests that social engineering or user-based exploitation methods may be necessary to trigger the vulnerability, though this does not diminish its overall risk profile.
Organizations should implement immediate mitigations including network segmentation to limit access to Oracle iSupport components, deployment of web application firewalls to monitor and filter HTTP traffic, and implementation of additional authentication controls. The ATT&CK framework categorizes this vulnerability under initial access techniques, specifically leveraging network-based exploitation methods that bypass traditional authentication mechanisms. Regular security assessments and patch management procedures should be enforced to prevent exploitation, while monitoring for unusual access patterns or unauthorized data modifications should be implemented across all Oracle E-Business Suite components. The vulnerability's presence in versions 12.1.1-12.1.3 underscores the importance of maintaining current software versions and applying security patches promptly to protect against known exploits in enterprise applications.
