CVE-2020-2855 in iSupport
Summary
by MITRE
Vulnerability in the Oracle iSupport product of Oracle E-Business Suite (component: Admin). 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-2020-2855 represents a critical security flaw within Oracle iSupport component of the Oracle E-Business Suite ecosystem. This vulnerability specifically affects versions 12.1.1 through 12.1.3, making it a widespread concern for organizations utilizing these older releases. The flaw resides within the Admin component of iSupport, which serves as a critical administrative interface for managing various business processes. The vulnerability's classification as easily exploitable indicates that attackers can leverage it without requiring specialized skills or extensive preparation, making it particularly dangerous in production environments where such systems are often accessible over networks.
The technical nature of this vulnerability stems from insufficient authentication mechanisms within the Oracle iSupport Admin component, allowing unauthenticated attackers to gain access through standard HTTP network connections. This represents a fundamental breakdown in the security model where the system fails to properly validate user credentials before granting access to sensitive administrative functions. The CVSS 3.0 scoring of 8.2 reflects the severity of the potential impact, with the vector indicating network-based attack surface (AV:N), low attack complexity (AC:L), no privilege requirements (PR:N), and requiring human interaction (UI:R). The score specifically emphasizes high confidentiality impact (C:H) and low integrity impact (I:L), indicating that while the primary concern is data exposure rather than modification, the potential for unauthorized access to critical data remains extremely severe.
The operational impact of this vulnerability extends beyond the immediate iSupport component, as the attack can significantly affect additional products within the Oracle E-Business Suite environment. This cascading effect occurs because iSupport often serves as an integration point or administrative hub that connects to various other modules within the suite. Successful exploitation can lead to unauthorized access to all Oracle iSupport accessible data, potentially exposing sensitive business information, customer records, financial data, and other critical organizational assets. The vulnerability also enables unauthorized update, insert, or delete operations against some of the accessible data, creating potential for data corruption or manipulation that could severely impact business operations and compliance requirements.
From a cybersecurity perspective, this vulnerability aligns with CWE-287 which addresses improper authentication issues, and maps to ATT&CK technique T1190 for exploit public-facing application, highlighting the network-based attack vector. Organizations should prioritize immediate remediation through Oracle's security patches or updates, as the vulnerability's low attack complexity and high impact make it an attractive target for malicious actors. The requirement for human interaction suggests that social engineering or targeted attacks may be necessary to complete the exploitation process, though this does not mitigate the overall risk. Security teams should implement network segmentation, monitor for unusual access patterns, and consider temporary access restrictions to minimize potential impact while permanent fixes are deployed. The vulnerability underscores the critical importance of maintaining current security patches and the risks associated with operating unsupported software versions in enterprise environments.
