Exploitation Conditions

The Internet Procurement Connector component of Oracle E-Business Suite 12.2.3-12.2.15 must be deployed and reachable by the attacker over HTTP - this is the default for any EBS installation that uses procurement integrations with external suppliers. No authentication, no privileges, no user interaction, and no special non-default configuration are required per the CVSS vector (AV:N/AC:L/PR:N/UI:N) and Oracle's 'Easily exploitable' classification. Practical limits on exploitation: the EBS web tier hosting the connector must be network-reachable by the attacker (many enterprises front EBS with VPN or restrict it to internal networks, which is the single most important limiting factor), the target instance must be in the supported 12.2.3-12.2.15 range, and exploitation is confined to data accessible via the connector - no availability impact (A:N) and no scope change (S:U), so the attacker cannot directly pivot to other EBS modules or the underlying host through this CVE alone.

Impact

Multiple signals converge to make this a top-tier priority for affected operators. The CVSS 9.1 vector (AV:N/AC:L/PR:N/UI:N) describes the worst practical case short of full compromise: remote, internet-reachable, no auth, no user interaction, low complexity - Oracle's own 'Easily exploitable' language reinforces this. The lack of an availability impact (A:N) suggests the bug is a data-access/integrity flaw rather than a memory corruption, which typically makes weaponization simpler and more reliable. No EPSS score, KEV listing, or public POC was provided in the input - so realistic exploitation likelihood cannot yet be quantified, but Oracle EBS has been heavily targeted historically (the 2023 Cl0p MOVEit campaign and the 2025 EBS zero-day campaigns) and ransomware affiliates monitor Oracle CPU advisories closely. Treat the absence of a KEV entry as a temporary state, not a safety signal; the 12.2.3-12.2.15 range covers virtually every supported 12.2 deployment, so the addressable target surface is large.

Exploit ScenarioDerived

An external attacker scans for internet-facing Oracle EBS 12.2 deployments (often identifiable by /OA_HTML/ paths and Oracle banners), sends crafted HTTP requests directly to Internet Procurement Connector endpoints without authenticating, and uses the resulting access to exfiltrate supplier, contract, and financial data and/or inject fraudulent procurement records to enable invoice fraud. Because the CVSS vector specifies AV:N/AC:L/PR:N/UI:N, the attack is a single-shot HTTP request and trivially automatable once endpoint details are known - no public exploit identified at time of analysis, but the simplicity of the bug class means a POC is likely to surface quickly after the May 2026 CPU advisory is dissected.

AnalysisAIv1 – May 28, 2026

Remote unauthenticated compromise of Oracle Internet Procurement Connector (a component of Oracle E-Business Suite versions 12.2.3 through 12.2.15) allows attackers to read, modify, create, or delete all data accessible to the component over HTTP. The CVSS 9.1 score reflects high confidentiality and integrity impact with low attack complexity and no privileges or user interaction required. No public exploit identified at time of analysis, but the trivial exploitability profile combined with EBS's history of being targeted (e.g., CVE-2025 Cl0p campaigns) makes this a priority patch for any internet-exposed deployment.

RemediationAI

Patch available per vendor advisory: apply the May 2026 Oracle Critical Patch Update (CPU) / Security Patch Update referenced at https://www.oracle.com/security-alerts/cspumay2026.html, which is the only Oracle-supported remediation path; exact fix version was not enumerated in the input data, so consult the advisory's patch matrix for your specific 12.2.x baseline. Until the CPU is applied, compensating controls include restricting network access to the EBS web tier so that Internet Procurement Connector endpoints are reachable only from trusted internal networks or via VPN (side effect: breaks any legitimate external supplier integrations that traverse those URLs), placing a WAF or reverse proxy in front of EBS to block unauthenticated requests to /OA_HTML/ and procurement connector paths (side effect: may block legitimate supplier portals - test before enforcing), and increasing audit logging on procurement tables to detect unauthorized create/modify/delete activity. Do not rely on perimeter controls alone - many EBS compromises in 2023-2025 occurred via internet-exposed instances or supplier portals that defenders believed were segmented.

Technical ContextAI · show details

Oracle E-Business Suite (EBS) is Oracle's flagship on-premises ERP platform, and the Internet Procurement Connector is a sub-component of the Internal Operations module used to bridge external procurement workflows with internal EBS modules over HTTP-based services. The affected CPE (cpe:2.3:a:oracle_corporation:oracle_internet_procurement_connector) covers all 12.2.x branches from 12.2.3 to 12.2.15, indicating the flaw exists in long-standing connector code rather than a recent feature. The tag 'Authentication Bypass' combined with the CVSS PR:N vector strongly suggests an unauthenticated request can reach data-modifying endpoints that should require an EBS session; no CWE was assigned by the reporter, but the impact profile (C:H/I:H with A:N) is characteristic of broken access control or missing authentication on a privileged HTTP endpoint (CWE-306 / CWE-862 class).

DescriptionCVE.org

Vulnerability in the Oracle Internet Procurement Connector 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 unauthenticated attacker with network access via HTTP to compromise Oracle Internet Procurement Connector. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Internet Procurement Connector accessible data as well as unauthorized access to critical data or complete access to all Oracle Internet Procurement Connector accessible data. CVSS 3.1 Base Score 9.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).

Executive ViewAI

Why It Matters

Oracle Internet Procurement Connector, embedded in E-Business Suite versions 12.2.3 through 12.2.15, is subject to a critical remote unauthenticated vulnerability (CVSS 9.1) enabling full data compromise-read, modify, create, or delete all procurement data without authentication or user interaction. No public exploit identified at time of analysis, but the trivial exploitability profile and history of EBS targeting create immediate organizational risk; no vendor-released patch identified at time of analysis requires urgent compensating controls.

Business Impact: Severe
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: (1) Network isolation-restrict Oracle Internet Procurement Connector access to internal networks only via segmentation or WAF rules; (2) Multi-factor authentication for all procurement system access; (3) Detailed logging and alerting on procurement data access, modification, and deletion events; (4) Regular access reviews for procurement systems; (5) Activation of incident response procedures for potential unauthorized access; (6) Vulnerability scanning and penetration testing of EBS deployments; (7) Temporary suspension of non-essential procurement transactions until remediation confirmed.
