CVE-2026-61267 in HCM Configuration Workbench
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle HCM Configuration Workbench product of Oracle E-Business Suite (component: Spreadsheet Loading). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle HCM Configuration Workbench. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle HCM Configuration Workbench accessible data as well as unauthorized read access to a subset of Oracle HCM Configuration Workbench accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle HCM Configuration Workbench. CVSS 3.1 Base Score 7.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).

This vulnerability exists within Oracle HCM Configuration Workbench component of Oracle E-Business Suite, specifically in the Spreadsheet Loading functionality that enables users to import data through spreadsheet files. The affected versions span from 12.2.3 through 12.2.15, representing a substantial portion of the Oracle EBS release cycle where this particular security flaw was present. The vulnerability is classified as easily exploitable due to its accessibility characteristics, allowing unauthenticated attackers to leverage network-based HTTP access to compromise the system without requiring any prior authentication credentials or privileged access.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the spreadsheet loading process. When users upload spreadsheet files containing configuration data, the system fails to properly validate the incoming data structure and user permissions, creating pathways for malicious actors to manipulate the underlying data processing functions. This flaw enables attackers to execute unauthorized operations including data modification, insertion, and deletion against specific portions of the Oracle HCM Configuration Workbench database. The vulnerability operates at the application layer where HTTP traffic is processed, making it particularly dangerous as it can be exploited remotely without requiring physical access or specialized equipment.
The operational impact of this vulnerability extends across multiple security domains as indicated by the CVSS 3.1 scoring system. Attackers can achieve unauthorized read access to sensitive configuration data subsets, potentially exposing confidential business information and organizational structures. The integrity compromise allows malicious modifications to existing data or creation of new entries that could disrupt normal business processes. Additionally, the availability impact creates opportunities for partial denial of service conditions where specific functionality within the Configuration Workbench becomes impaired or inaccessible to legitimate users. This vulnerability directly maps to CWE-284 (Improper Access Control) and CWE-352 (Cross-Site Request Forgery) categories, reflecting fundamental flaws in authorization and input validation controls.
From an adversary perspective, this vulnerability aligns with ATT&CK technique T1213.002 (Data from Information Repositories) and T1499.004 (Endpoint Denial of Service) within the enterprise attack framework. The low attack complexity and lack of required privileges make it particularly attractive to threat actors seeking quick gains in compromised environments. Organizations utilizing affected Oracle EBS versions should immediately implement network segmentation measures, deploy web application firewalls to monitor and filter spreadsheet upload requests, and consider disabling unnecessary spreadsheet loading functionality until patches are applied. The vulnerability represents a significant risk to data integrity and business continuity within organizations relying on Oracle HCM Configuration Workbench for critical human capital management operations.
