1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires possession of high-privileged credentials within Oracle E-Business Suite (PR:H per the vendor-provided CVSS vector), with network reachability to the Oracle Purchasing Internal Operations component via HTTP. The vulnerability affects EBS releases 12.2.3 through 12.2.15 only; organizations on 12.1.x or post-12.2.15 releases (if any) are not confirmed affected. No user interaction is required, no special non-default configuration is described as a prerequisite, and Oracle's characterization of 'easily exploitable' implies no complex exploit preconditions beyond credential possession. The principal limiting factor for opportunistic exploitation is the high-privilege requirement - this reduces mass-exploitation risk but does not protect against targeted attacks using stolen or misused privileged accounts. |
| Impact | The CVSS 3.1 base score of 7.2 (High) reflects full CIA impact (C:H/I:H/A:H) with low attack complexity and no user interaction, moderated only by the high-privilege requirement (PR:H). Oracle's own characterization of the flaw as 'easily exploitable' is the critical risk amplifier here - it signals that the technical exploitation barrier is negligible once credentials are in hand, a scenario realistic via phishing, credential stuffing against EBS login portals, or insider threat. The vulnerability tag 'Information Disclosure' in the ENISA EUVD record understates the impact described in the NVD entry, which explicitly cites takeover; security teams should rely on the CVSS C:H/I:H/A:H impact rather than the tag. No EPSS data was provided, and no CISA KEV listing exists, so active exploitation is not confirmed. For organizations with Oracle EBS internet-facing or accessible from broad internal segments, the high-privilege constraint is the single most important risk limiter - environments with tightly controlled privileged account assignments face substantially lower realistic risk than those with permissive access models. |
| Exploit ScenarioDerived | An attacker who has obtained high-privileged Oracle EBS credentials - through phishing a procurement manager, credential stuffing against an internet-facing EBS login portal, or via a malicious insider - sends specially crafted HTTP requests to the Internal Operations component of Oracle Purchasing over the network. Because Oracle rates this as 'easily exploitable' with AC:L, no advanced tooling or timing coordination is required after credential acquisition, and successful exploitation yields complete control of the Oracle Purchasing system, enabling exfiltration of supplier and procurement data, manipulation of purchase orders, and disruption of purchasing operations. No public exploit code has been identified at time of analysis. |

Alert meAnalysisAIv1 – Aug 19, 2026
Oracle Purchasing, a procurement module of Oracle E-Business Suite versions 12.2.3 through 12.2.15, exposes a high-severity network-exploitable vulnerability in its Internal Operations component that enables full system takeover - complete loss of confidentiality, integrity, and availability. Oracle itself classifies this as 'easily exploitable' despite the high-privilege requirement (PR:H), meaning that once an attacker possesses elevated credentials, exploitation presents no meaningful technical barrier. No public exploit code has been identified and no CISA KEV listing exists at time of analysis, but the full CIA impact and low attack complexity make this a priority patching target for any organization running internet-exposed or broadly network-accessible Oracle EBS deployments.
RemediationAI
Apply Oracle's Critical Patch Update (CPU) for August 2026, available at https://www.oracle.com/security-alerts/cspuaug2026.html. Oracle has not disclosed a specific patched version number in the data available at time of analysis - consult the CPU advisory documentation for the exact patch bundle applicable to your EBS 12.2.x release. As compensating controls pending patching, restrict network access to the Oracle Purchasing Internal Operations component using web application firewall rules or network-layer ACLs to limit exposure to trusted internal IP ranges, reducing the attacker's reachable surface; note this does not protect against insider or compromised-credential scenarios. Separately, audit privileged account assignments within Oracle EBS Purchasing and enforce least-privilege principles to reduce the pool of accounts that could be leveraged - this directly addresses the PR:H exploitation prerequisite. Neither control eliminates the vulnerability; patching per the CPU remains the required remediation.

Technical ContextAI · show details
Oracle E-Business Suite (EBS) is Oracle's flagship enterprise resource planning platform, and the Purchasing module manages procurement workflows including purchase orders, requisitions, and supplier interactions. The affected component, 'Internal Operations,' is reachable via HTTP over the network. The CVSS vector AV:N/AC:L/PR:H/UI:N/S:U indicates a fully network-accessible attack surface requiring no user interaction and no special timing or race conditions - only high-privileged credentials serve as the gate. No CWE classification was provided by the reporter or NVD, which precludes definitive root-cause categorization; however, the combination of 'easily exploitable,' network delivery, and full takeover impact is consistent with severe authorization bypass, server-side injection (e.g., SQL injection or OS command injection), or a broken access control flaw within the Internal Operations processing layer. The affected version range 12.2.3 through 12.2.15 spans a broad and currently supported EBS release window, affecting the majority of organizations still on the 12.2.x branch.

DescriptionCVE.org
Vulnerability in the Oracle Purchasing 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 high privileged attacker with network access via HTTP to compromise Oracle Purchasing. Successful attacks of this vulnerability can result in takeover of Oracle Purchasing. CVSS 3.1 Base Score 7.2 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
Executive ViewAI
Oracle Purchasing in E-Business Suite versions 12.2.3-12.2.15 contains a network-exploitable vulnerability enabling complete system compromise-total loss of data confidentiality, integrity, and availability across the procurement platform. Although no public exploit code has been identified to date, any user with elevated administrative credentials can trivially exploit the flaw to achieve full system control; organizations running Internet-exposed or broadly accessible Oracle EBS deployments face immediate risk of procurement system takeover and cascading impact to supply chain operations and financial controls.
No vendor-released patch identified at time of analysis. Interim mitigations: restrict network access to Purchasing module to authenticated, high-privilege users only; enforce multi-factor authentication for all elevated-privilege accounts with Oracle EBS access; implement continuous logging and real-time alerting on high-privilege user activity and unexpected Purchasing module operations; evaluate network segmentation or air-gapping of Oracle EBS if operationally feasible; conduct enhanced user access reviews to minimize the number of accounts holding high-privilege credentials; maintain current incident response procedures for potential unauthorized procurement transactions or data exfiltration.
