Exploitation Conditions

Exploitation targets the Internal Operations component of Oracle Bills of Material within Oracle E-Business Suite versions 12.2.3 through 12.2.15, reachable over the network via HTTP. It is NOT exploitable by anonymous attackers: the CVSS vector's PR:H requires the attacker to already hold a high-privilege authenticated account on the EBS instance. Exploitation is further limited by HIGH attack complexity (AC:H), meaning success depends on conditions the attacker cannot fully control (e.g., specific timing, state, or configuration), making reliable exploitation difficult. The offsetting factor is the scope change (S:C): a successful attack can significantly impact additional Oracle products beyond Bills of Material, so defenders should weight the blast radius higher than the difficulty alone would suggest. No user interaction is required (UI:N).

Impact

This is a genuinely high-CVSS score (7.2) but the real-world risk is materially tempered by its exploitation metrics, making it a lower practical priority than the headline number suggests. The CVSS vector (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C) shows network reach but requires HIGH attack complexity (AC:H) and HIGH privileges (PR:H) - meaning the attacker must already hold a privileged, authenticated account on the EBS instance AND overcome conditions outside their control. The elevated score is driven largely by the scope change (S:C) and the HIGH integrity impact (I:H), not by ease of access. No EPSS score was provided in the input, so exploitation probability cannot be quantified. The CVE is NOT listed in CISA KEV and no POC was supplied, so exploitation status is 'no public exploit identified at time of analysis.' No SSVC decision data was provided. Signals are internally consistent: a high-privilege, high-complexity flaw is unlikely to see opportunistic mass exploitation, favoring a targeted-abuse or insider/post-compromise profile over widespread automated attack. The scope change is the one signal warranting elevated attention, as impact can propagate beyond Bills of Material to additional EBS products.

Exploit ScenarioDerived

An attacker who has already obtained high-privilege authenticated access to an Oracle E-Business Suite instance (e.g., a compromised privileged application account or a malicious insider) sends crafted HTTP requests to the Bills of Material Internal Operations component. By exploiting the flaw under the required non-trivial conditions (AC:H), they modify or delete critical BoM data and, due to the scope change, affect additional connected Oracle products. No public exploit code is known at the time of analysis.

AnalysisAIv1 – Oct 21, 2026

High-privileged authenticated attackers can achieve unauthorized data manipulation and partial denial of service in Oracle Bills of Material (Oracle E-Business Suite 12.2.3-12.2.15) by exploiting a difficult-to-exploit flaw over HTTP, with scope change potentially affecting additional Oracle products. The vulnerability requires network access, high attack complexity (AC:H), and a high-privilege account (PR:H); no public exploit code or active exploitation has been identified at time of analysis. EPSS risk was not provided, but the CVSS 7.2 score reflects an integrity-heavy impact profile.

RemediationAI

Patch available per vendor advisory: apply the Oracle Critical Patch Update (CPU) for October 2026, which addresses CVE-2026-101822 for Oracle E-Business Suite 12.2.3-12.2.15; see https://www.oracle.com/security-alerts/cpuoct2026.html for the exact patch set and installation instructions. Because exploitation requires a high-privilege authenticated account and high attack complexity, prioritize restricting network access to Bills of Material HTTP endpoints and enforcing least-privilege accounts as compensating controls-though locking down endpoints may disrupt legitimate supply-chain users. Monitor high-privileged session activity for anomalous data changes or partial denial-of-service patterns, and note that no public exploit code or active exploitation has been identified, so emergency out-of-band patching is not indicated by current intelligence.

Technical ContextAI · show details

Oracle Bills of Material is a supply-chain manufacturing module within Oracle E-Business Suite, and the Internal Operations component exposes HTTP endpoints used for bill-of-material processing. The CVSS vector AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:H/A:L indicates the flaw is remotely reachable but requires a high-privilege authenticated account and conditions outside the attacker's control (AC:H), while the scope change (S:C) means a successful exploit can affect other Oracle products beyond Bills of Material. No CWE was assigned, so the root-cause class is undocumented; the impact profile is primarily integrity (I:H) with limited confidentiality (C:L) and availability (A:L) effects.

DescriptionCVE.org

Vulnerability in the Oracle Bills of Material product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Difficult to exploit vulnerability allows high privileged attacker with network access via HTTP to compromise Oracle Bills of Material. While the vulnerability is in Oracle Bills of Material, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Bills of Material accessible data as well as unauthorized read access to a subset of Oracle Bills of Material accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Bills of Material. CVSS 3.1 Base Score 7.2 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:H/A:L).

Executive ViewAI

Why It Matters

A high-severity integrity flaw in Oracle E-Business Suite's Bills of Material module (versions 12.2.3 through 12.2.15) allows a privileged user to tamper with manufacturing and supply-chain master data, with possible spillover into other Oracle products via scope change. Because Bills of Material feeds production planning, procurement, and product costing, the exposure is less about system downtime and more about corrupted records propagating into operational and financial decisions. No patch is currently available, so risk must be managed through access restriction and monitoring of privileged accounts until Oracle releases a fix.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: restrict network reachability to the E-Business Suite Bills of Material endpoints; aggressively reduce and review accounts holding the high privileges required (PR:H); enable verbose auditing and SIEM alerting on bill-of-material and item master changes; enforce least privilege and separation of duties for manufacturing data administration; run periodic integrity reconciliation of BoM records against trusted baselines; and monitor Oracle's advisory channel for the eventual CPU fix.
