Network HTTP interface (AV:N) with low complexity and no interaction, but requires an authenticated low-privileged session (PR:L); vendor states full Payroll takeover, so C/I/A all High.

Lifecycle Timeline
2DescriptionCVE.org
Vulnerability in the Oracle Payroll 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 Payroll. Successful attacks of this vulnerability can result in takeover of Oracle Payroll. CVSS 3.1 Base Score 8.8 (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:H).
AnalysisAI
Full compromise of Oracle Payroll (Oracle E-Business Suite, Internal Operations component) is possible when a low-privileged attacker sends crafted HTTP requests to the affected application, per Oracle's July 2026 Critical Patch Update. The flaw affects EBS releases 12.2.3 through 12.2.15 and, given the CVSS 3.1 base score of 8.8 with high confidentiality, integrity, and availability impact, allows takeover of Oracle Payroll. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the low attack complexity and 'easily exploitable' vendor characterization warrant prompt patching.
Technical ContextAI
Oracle Payroll is a module of Oracle E-Business Suite (EBS), a large enterprise ERP/HCM platform typically deployed as a multi-tier Java/PL-SQL web application fronted by Oracle HTTP Server and backed by an Oracle Database. The vulnerable 'Internal Operations' component is reached over HTTP, indicating the issue lies in a network-exposed application interface rather than a backend batch process. Oracle did not assign a CWE (CWE: N/A) and does not disclose root-cause detail in CPU advisories, so the precise weakness class (e.g., injection, access control, or deserialization) cannot be determined from the available data; the 'Information Disclosure' tag plus C:H/I:H/A:H impact suggests a flaw that leaks data and also permits state modification, consistent with a broken access-control or injection defect.
RemediationAI
Apply the fixes in Oracle's July 2026 Critical Patch Update, which is the vendor-released patch for this issue; see https://www.oracle.com/security-alerts/cpujul2026.html for the exact EBS 12.2 patch bundle applicable to your release (Oracle ships this as CPU patch sets rather than a single incremental version number, so the specific released patched version is not independently confirmed here beyond the CPU). Because exploitation is over HTTP and requires only low privileges, until patching is complete restrict network access to the EBS/Payroll web tier to trusted internal networks and VPNs, place the application behind a WAF or reverse proxy to filter anomalous requests to Internal Operations endpoints, and tighten Payroll application-role assignments to minimize the population of low-privileged accounts that could reach the vulnerable component. These controls reduce exposure but do not remove the flaw and may impact legitimate remote users of the Payroll self-service interfaces, so schedule the CPU as the durable remediation.
