Vulnerability in the Oracle E-Business Tax 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 logon to the infrastructure where Oracle E-Business Tax executes to compromise Oracle E-Business Tax. Successful attacks of this vulnerability can result in takeover of Oracle E-Business Tax. CVSS 3.1 Base Score 7.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
AnalysisAI
Local privilege-driven takeover in Oracle E-Business Tax (a component of Oracle E-Business Suite 12.2.3 through 12.2.15) lets a low-privileged attacker who can log on to the host infrastructure fully compromise the E-Business Tax module. Oracle rates it CVSS 3.1 7.8 with complete confidentiality, integrity, and availability impact and describes it as easily exploitable. No public exploit was identified at time of analysis, and it is not listed in CISA KEV.
Technical ContextAI
Oracle E-Business Suite is a large enterprise ERP/financials platform; the E-Business Tax module (component: Internal Operations) centralizes tax determination, calculation, and reporting across the suite's financial applications. The CVSS vector (AV:L) indicates the flaw is reached through the local infrastructure rather than the network, meaning the attacker leverages an existing foothold or account on a host where E-Business Tax executes. No CWE was assigned in the source data (CWE: N/A), so the precise root-cause class - e.g., improper authorization, injection, or insecure internal-operations handling - cannot be confirmed from the provided intelligence; Oracle's language ('takeover' with only low privileges required) is consistent with a privilege-escalation or authorization weakness inside the module.
RemediationAI
Apply the fixes delivered in the Oracle Critical Patch Update of July 2026 (https://www.oracle.com/security-alerts/cpujul2026.html) - Patch available per vendor advisory; an exact standalone fix version was not included in the source data, so identify the specific patch for your 12.2.x level from the CPU matrix. Because exploitation requires a local logon, effective compensating controls until patching include tightly restricting and auditing interactive and application logon accounts on E-Business Tax hosts, enforcing least privilege for application and OS users, and monitoring for anomalous local activity by low-privilege accounts; the trade-off is operational overhead and possible disruption to legitimate batch or operations users if access is curtailed too aggressively. Given full CIA impact, prioritize patching hosts where many users hold logon rights.
