CVE-2020-2839 in Service Intelligence
Summary
by MITRE
Vulnerability in the Oracle Service Intelligence product of Oracle E-Business Suite (component: Internal Operations- Search). 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 Service Intelligence. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Service Intelligence, 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 Service Intelligence accessible data as well as unauthorized update, insert or delete access to some of Oracle Service Intelligence 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-2020-2839 resides within Oracle Service Intelligence, a component of the Oracle E-Business Suite ecosystem that operates under the Internal Operations-Search framework. This security flaw affects specific versions ranging from 12.1.1 through 12.1.3, representing a significant risk to organizations utilizing these older releases. The vulnerability's classification as easily exploitable indicates that attackers can leverage network-based HTTP access without requiring authentication credentials, presenting a substantial threat vector that could compromise the integrity and confidentiality of sensitive business data.
The technical implementation of this vulnerability stems from insufficient input validation mechanisms within the search functionality of Oracle Service Intelligence. Attackers can exploit this weakness through HTTP requests that manipulate search parameters to gain unauthorized access to underlying data repositories. The vulnerability's impact extends beyond the immediate component as it can affect additional Oracle products within the suite, creating cascading security implications throughout the enterprise environment. The CVSS 3.0 scoring system rates this vulnerability at 8.2, reflecting high confidentiality impact and moderate integrity impact, with the vector indicating network accessibility, low attack complexity, no privilege requirements, and requiring user interaction for successful exploitation.
The operational consequences of this vulnerability are severe and multifaceted, potentially enabling attackers to achieve complete access to all Oracle Service Intelligence data while also allowing unauthorized modification of information. This represents a critical security gap that could lead to data breaches, information tampering, and unauthorized system modifications. The requirement for human interaction suggests that social engineering or targeted phishing attacks might be necessary to initiate exploitation, though the underlying vulnerability remains accessible to any network-connected attacker. Organizations with outdated Oracle E-Business Suite installations are particularly at risk, as the vulnerability affects versions that may no longer receive comprehensive security updates.
Mitigation strategies should prioritize immediate patching of affected Oracle Service Intelligence versions to address the root cause of the vulnerability. Organizations should implement network segmentation and access controls to limit exposure of the vulnerable components to untrusted networks. Security monitoring should be enhanced to detect anomalous search requests that may indicate exploitation attempts, while also maintaining regular vulnerability assessments to identify similar weaknesses in other Oracle products. The vulnerability aligns with CWE-20, representing a weakness in input validation that allows for injection attacks, and could be categorized under ATT&CK technique T1190 for exploitation of remote services. Additionally, implementing web application firewalls and restricting HTTP access to the affected search functionality provides additional protective layers that can help prevent unauthorized access while the permanent fixes are deployed.
