CVE-2018-2997 in Scripting
Summary
by MITRE
Vulnerability in the Oracle Scripting component of Oracle E-Business Suite (subcomponent: Script Author). Supported versions that are affected are 12.1.1, 12.1.2 and 12.1.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Scripting. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Scripting, 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 Scripting accessible data as well as unauthorized update, insert or delete access to some of Oracle Scripting 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-2018-2997 resides within the Oracle Scripting component of Oracle E-Business Suite, specifically affecting the Script Author subcomponent. This flaw represents a critical security weakness that impacts versions 12.1.1, 12.1.2, and 12.1.3 of the enterprise suite. The vulnerability operates at the application layer and specifically targets the scripting functionality that enables users to create and manage automated processes within the Oracle E-Business environment. The affected component allows for the execution of scripts that can manipulate database operations and access sensitive business data through the web interface.
The technical implementation of this vulnerability stems from inadequate input validation and authentication mechanisms within the Oracle Scripting framework. Attackers can exploit this weakness through unauthenticated HTTP network connections, making it particularly dangerous as it requires no prior credentials or privileged access to initiate exploitation attempts. The vulnerability's classification as easily exploitable indicates that the attack vector is straightforward and does not require sophisticated techniques or extensive reconnaissance. The flaw allows for unauthorized access to critical data and provides the capability for data modification, including unauthorized update, insert, or delete operations within the Oracle Scripting accessible data domains.
From an operational impact perspective, this vulnerability creates significant risk for organizations utilizing Oracle E-Business Suite as it can result in complete compromise of sensitive business data and operational integrity. The CVSS 3.0 score of 8.2 reflects the high severity of this flaw, with confidentiality impact rated as high and integrity impact as low, indicating that while the primary concern is data exposure, the modification capabilities present substantial risk to data integrity. The vulnerability's potential to impact additional products through the attack vector demonstrates its cascading effects within enterprise environments where Oracle E-Business Suite components often integrate with other systems. The requirement for human interaction from a person other than the attacker suggests that social engineering or targeted user engagement may be necessary to complete exploitation, though this does not mitigate the overall threat level.
Security professionals should implement immediate mitigations including applying the relevant Oracle critical patch updates, implementing network segmentation to limit access to the affected components, and conducting thorough access reviews to identify any unauthorized script execution capabilities. The vulnerability aligns with CWE-20 Improper Input Validation and follows patterns consistent with ATT&CK technique T1059 Command and Scripting Interpreter, where adversaries leverage scripting capabilities to gain unauthorized access. Organizations should also consider implementing web application firewalls to monitor and control HTTP traffic to the affected Oracle Scripting interfaces, while maintaining detailed audit logs of script execution activities to detect potential exploitation attempts. The vulnerability's characteristics make it particularly attractive to attackers seeking to establish persistent access to enterprise databases and business-critical applications within Oracle E-Business Suite environments.
