Lifecycle Timeline
2DescriptionCVE.org
Vulnerability in the Oracle HRMS (UK) product of Oracle E-Business Suite (component: UK Payroll). 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 creation, deletion or modification access to critical data or all 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 7.1 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L).
AnalysisAI
Data tampering and partial denial of service in Oracle HRMS (UK) - the UK Payroll component of Oracle E-Business Suite (EBS) versions 12.2.3 through 12.2.15 - lets a low-privileged, authenticated attacker with HTTP network access create, modify or delete critical HRMS data and partially degrade the service. Oracle rates it CVSS 3.1 7.1 and describes it as 'easily exploitable' (AC:L), meaning any account holder on the EBS instance can abuse it. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, so exploitation is currently theoretical rather than observed.
Technical ContextAI
Oracle HRMS (UK) is the United Kingdom localization of Oracle's Human Resources Management System, delivered as a module within Oracle E-Business Suite; the affected code is specifically the UK Payroll component. EBS is a large web-based ERP platform whose modules are reached over HTTP through the EBS application tier (Oracle HTTP Server / WebLogic front end) against a shared Oracle database. Because the flaw permits unauthorized modification of 'critical data or all Oracle HRMS (UK) accessible data,' the root cause is most consistent with a broken access control / missing authorization check (CWE-862/CWE-284 class) in a payroll servlet or page, though the CWE was not populated (N/A) in the source data and cannot be confirmed. No CPE strings were supplied; affected products are identified only from the Oracle CPU text and the ENISA EUVD record.
RemediationAI
Apply the fixes in the Oracle July 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpujul2026.html); Oracle addresses EBS flaws through cumulative CPU patches applied to the 12.2 application tier, so install the current CPU patch level for your EBS 12.2 release rather than a single point version - an exact standalone fix version was not published in the source data (Patch available per vendor advisory). Until patching, reduce exposure by tightening HRMS/Payroll responsibility and menu assignments so only trusted staff hold accounts that can reach the UK Payroll functions (this directly counters the PR:L requirement, at the cost of an administrative review of role grants), and restrict network reachability of the EBS application tier to trusted corporate networks/VPN rather than exposing it to the broader internet (may inconvenience remote or self-service users). Increase auditing on payroll data changes to detect unauthorized modification while the patch is scheduled.
