CVE-2026-62473 in Installed Base
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle Installed Base product of Oracle E-Business Suite (component: Create Item Instance). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Installed Base. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Installed Base accessible data as well as unauthorized access to critical data or complete access to all Oracle Installed Base accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Installed Base. CVSS 3.1 Base Score 8.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L).

This vulnerability exists within Oracle E-Business Suite's Installed Base component, specifically in the Create Item Instance functionality where a low privileged attacker with network access via HTTP can exploit a security flaw. The affected versions span from 12.2.3 through 12.2.15, representing a significant attack surface across multiple release cycles of Oracle's enterprise software suite. The vulnerability is classified as easily exploitable due to its accessibility over network protocols and the relatively low privilege requirements needed for successful exploitation.
The technical flaw stems from insufficient input validation and access control mechanisms within the item instance creation process, allowing unauthorized users to manipulate the system through crafted HTTP requests. This weakness enables attackers to perform unauthorized operations including creating, deleting, or modifying critical data within the Installed Base subsystem. The vulnerability operates at a fundamental level where proper authorization checks fail to validate user privileges before executing data manipulation operations, creating a pathway for privilege escalation and data compromise.
The operational impact of this vulnerability extends beyond simple data modification to encompass complete system compromise potential. Attackers can achieve unauthorized access to all Oracle Installed Base accessible data, which may include sensitive inventory information, asset tracking details, and related business-critical data. Additionally, the vulnerability enables partial denial of service conditions that can disrupt normal business operations and reduce system availability for legitimate users. The CVSS 3.1 base score of 8.3 reflects the high severity across confidentiality, integrity, and availability vectors, indicating a substantial risk to enterprise security.
From a cybersecurity framework perspective, this vulnerability aligns with CWE-285 (Improper Authorization) and CWE-352 (Cross-Site Request Forgery) categories, representing weaknesses in access control mechanisms that allow unauthorized actions. The attack vector follows ATT&CK technique T1078 (Valid Accounts) and T1566 (Phishing) as attackers may leverage compromised credentials or exploit the vulnerability to establish persistent access. Organizations should implement immediate mitigations including applying Oracle's security patches, strengthening network segmentation, implementing web application firewalls, and conducting thorough access control reviews to prevent unauthorized exploitation of this critical vulnerability that could compromise enterprise data integrity and availability.
The vulnerability demonstrates a classic example of insufficient authorization controls in enterprise applications where administrative functions remain accessible to unauthorized users. The low attack complexity combined with high impact makes this particularly dangerous as it requires minimal skill or resources for successful exploitation. Security teams should prioritize patch management processes and implement comprehensive monitoring solutions to detect suspicious activities related to item instance creation and data manipulation attempts within the Oracle E-Business Suite environment.
