CVE-2026-62528
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle HCM Configuration Workbench product of Oracle E-Business Suite (component: Install). 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 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 6.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).

This vulnerability resides within Oracle HCM Configuration Workbench, a critical component of the Oracle E-Business Suite ecosystem that manages human capital management configurations. The flaw exists specifically in the Install component and affects all versions from 12.2.3 through 12.2.15, representing a significant attack surface that spans multiple release cycles. The vulnerability's classification as easily exploitable indicates that attackers with minimal technical expertise can leverage this weakness, making it particularly dangerous for organizations that maintain these legacy systems. The attack vector requires only network access via HTTP, eliminating the need for complex prerequisites or specialized tools, which significantly broadens the potential threat landscape.
The technical nature of this vulnerability stems from insufficient authorization controls within the installation and configuration processes of Oracle HCM Configuration Workbench. Attackers with low privileges can exploit this weakness to perform unauthorized operations including data modification through update, insert, and delete commands against sensitive configuration data. Additionally, the vulnerability enables unauthorized read access to a subset of accessible data, potentially exposing confidential business information and configuration parameters that should remain protected. The partial denial of service component indicates that attackers can disrupt system availability, though not completely incapacitating the application, which still represents a substantial operational risk for businesses relying on continuous HCM functionality.
The CVSS 3.1 score of 6.3 reflects the balanced impact across confidentiality, integrity, and availability domains, with each component rated as low to moderate. The attack complexity is classified as low, meaning exploitation does not require specialized circumstances or advanced techniques, while the privilege requirement is also low, indicating that even unauthenticated users with basic network access can potentially compromise the system. This vulnerability aligns with CWE-284 (Improper Access Control) and maps to ATT&CK technique T1078 (Valid Accounts) and T1566 (Phishing) as attackers may leverage this weakness after gaining initial network access through other means. The impact on confidentiality is limited to a subset of accessible data rather than complete database exposure, but the integrity implications are significant due to potential unauthorized modifications to critical configuration parameters that govern HR processes.
Organizations should implement immediate mitigations including applying the latest Oracle security patches and updates, which would address the underlying authorization flaws in the Install component. Network segmentation and access controls should be enhanced to limit HTTP access to only authorized personnel and systems, while monitoring solutions should be deployed to detect unusual patterns of access to configuration workbench components. The implementation of role-based access controls and principle of least privilege should be reviewed and strengthened to ensure that users have appropriate authorization levels for their specific functions. Regular vulnerability assessments and penetration testing should be conducted to identify similar authorization weaknesses in other Oracle E-Business Suite components, particularly those involving installation and configuration processes that may present similar attack surfaces. Additionally, organizations should consider implementing web application firewalls and enhanced logging to detect and prevent exploitation attempts targeting this specific vulnerability class.
