CVE-2026-62453 in HRMS
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle HRMS (UK) product of Oracle E-Business Suite (component: Internal Operations). 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 HRMS (UK). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle HRMS (UK) accessible data as well as unauthorized read access to a subset of Oracle HRMS (UK) accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle HRMS (UK). 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 HRMS (UK) component of the Oracle E-Business Suite ecosystem, specifically targeting the Internal Operations functionality. The affected versions span from 12.2.3 through 12.2.15, indicating a significant attack surface across multiple patch levels of this enterprise resource planning module. The vulnerability's classification as easily exploitable suggests that attackers with minimal technical expertise and network access via HTTP protocols can successfully compromise the system, making it particularly dangerous in production environments where such access may be more readily available.
The technical flaw manifests as a privilege escalation vulnerability that allows low-privileged attackers to gain unauthorized access to critical system resources. This weakness enables attackers to perform unauthorized update, insert, or delete operations against specific Oracle HRMS (UK) data sets, while simultaneously providing read access to sensitive information within the system's accessible data repository. Additionally, the vulnerability can be leveraged to execute partial denial of service attacks that compromise system availability. The CVSS 3.1 base score of 6.3 reflects the balanced impact across confidentiality, integrity, and availability domains, with the vector indicating network-based attack surface (AV:N), low attack complexity (AC:L), and low privilege requirements (PR:L) for successful exploitation.
The operational impact of this vulnerability extends beyond simple data compromise to include potential business disruption through partial system unavailability. Organizations utilizing Oracle HRMS (UK) in their payroll, human resources, or financial processing workflows face significant risk when this vulnerability exists within their environment, as attackers could manipulate critical employee data, financial records, or operational parameters. The partial denial of service capability further compounds the risk by potentially disrupting business operations during critical periods such as payroll processing or year-end financial closing activities.
Security professionals should implement immediate mitigations including network segmentation to restrict HTTP access to Oracle HRMS (UK) components, deployment of web application firewalls to monitor and filter suspicious requests, and implementation of principle of least privilege controls for system accounts. Organizations must also ensure that all affected versions are patched according to Oracle's security advisory schedule while maintaining continuous monitoring for exploitation attempts through network intrusion detection systems and application logs. This vulnerability aligns with CWE-284 (Improper Access Control) and may be mapped to ATT&CK technique T1078 (Valid Accounts) and T1499 (Endpoint Denial of Service) within the enterprise security framework, emphasizing the need for comprehensive defensive measures across multiple security domains.
