CVE-2020-2872 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-2020-2872 resides within Oracle iSupport, a component of the Oracle E-Business Suite ecosystem that serves as a customer support portal for managing service requests and technical issues. This flaw specifically affects versions 12.1.1 through 12.1.3, representing a significant security gap in Oracle's enterprise support infrastructure. The vulnerability operates within the Profile component of iSupport, which handles user configuration and access controls, making it a critical entry point for unauthorized system access.
This security flaw constitutes a network-based vulnerability that can be exploited through HTTP protocols without requiring authentication credentials from the attacker. The CVSS 3.0 scoring system rates this vulnerability at 8.2, indicating a high severity level that reflects both confidentiality and integrity impacts. The attack vector AV:N (network) combined with low attack complexity AC:L (low) and no privileges required PR:N (none) creates a particularly dangerous scenario where unauthorized actors can exploit this weakness with minimal technical expertise. The requirement for user interaction UI:R (required) suggests that while the attack itself may be automated, human involvement is necessary for successful exploitation, typically through social engineering or phishing techniques that prompt users to interact with malicious payloads.
The operational impact of this vulnerability extends beyond the immediate iSupport component, potentially affecting the broader Oracle E-Business Suite environment and connected systems. Successful exploitation enables attackers to gain unauthorized access to critical data within Oracle iSupport, including sensitive customer information, support tickets, and technical documentation. The vulnerability also grants unauthorized update, insert, or delete capabilities for certain data within the system, allowing attackers to modify or corrupt information that could disrupt business operations or compromise system integrity. This multi-faceted impact aligns with CWE-284 (Improper Access Control) and represents a classic privilege escalation scenario that could enable lateral movement within enterprise networks.
Security professionals should recognize this vulnerability through its alignment with ATT&CK framework techniques including T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS) where attackers might leverage the HTTP interface to establish persistent access. The vulnerability's characteristics also relate to the broader category of insecure direct object references and improper authentication mechanisms that commonly appear in enterprise web applications. Organizations should implement immediate mitigations including network segmentation, web application firewalls, and access control reviews to protect against exploitation attempts, while also planning for comprehensive patch management to address the root cause within the Oracle E-Business Suite components.
