Exploitation Conditions

Exploitation requires a legitimate user other than the attacker to perform an action that triggers the flaw (UI:R) - the attacker cannot complete the attack alone and must lure or socially engineer a victim interacting with the Oracle Application Object Library over HTTP. Oracle rates it 'Difficult to exploit' (AC:H), indicating additional conditions or timing/configuration dependencies beyond attacker control must be met. No authentication is required (PR:N, unauthenticated). Limiting factors: affected deployments are constrained to EBS versions 12.2.3 through 12.2.15, there is no availability impact (A:N), and impact is confined to the vulnerable component (S:U). The mandatory victim interaction plus high complexity are the primary realistic risk limiters despite the network-reachable, unauthenticated entry point.

Impact

This is a medium-severity issue (CVSS 3.1 base 6.8) whose real-world priority is moderated by two significant limiting signals in the vendor-supplied vector: AC:H (high attack complexity, explicitly described by Oracle as 'Difficult to exploit') and UI:R (requires human interaction from a person other than the attacker). While AV:N/PR:N means the attacker needs no credentials and can reach the target over HTTP, the dependency on tricking a legitimate user and the non-trivial exploitation conditions substantially lower the probability of opportunistic, widespread abuse. The impact is meaningful where it lands - C:H and I:H (unauthorized read and create/delete/modify of critical or all Application Object Library-accessible data) - but A:N means no availability/denial-of-service effect and S:U means the impact is contained to the vulnerable component. No EPSS score, CISA KEV listing, or public POC is present in the provided data, so there is no evidence of active exploitation or exploit availability at time of analysis; this reads as a 'patch in the normal Oracle CPU cycle' item rather than an emergency. Note a signal conflict to verify: the input Tags label this 'Authentication Bypass,' but the description and CVSS vector describe an unauthenticated, user-interaction-dependent data compromise (classic tricked-victim pattern), not a bypass of an authentication control - the tag should be treated with skepticism pending vendor confirmation.

Exploit ScenarioDerived

An unauthenticated attacker crafts a malicious HTTP request or link targeting a vulnerable Oracle Application Object Library instance (EBS 12.2.3-12.2.15) and lures a legitimate user into triggering it (e.g., clicking a link while authenticated to the application). Because exploitation is difficult (AC:H) and depends on that victim interaction (UI:R), success is not guaranteed, but a successful attack yields unauthorized read and create/delete/modify access to critical or all Application Object Library-accessible data. No public exploit identified at time of analysis.

AnalysisAIv1 – Oct 21, 2026

Oracle E-Business Suite 12.2.3 through 12.2.15 has an unauthenticated HTTP attack path in the Application Object Library Core component that can lead to unauthorized creation, deletion, or modification of critical data and unauthorized read access. The vendor vector requires a non-attacker user to interact with the application and rates exploitation as high complexity (CVSS 3.1 6.8, AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N), so practical risk is constrained by the need to lure or socially engineer a legitimate user; no public exploit has been identified at time of analysis.

RemediationAI

Apply the Oracle E-Business Suite fix from the October 2026 Critical Patch Update advisory at https://www.oracle.com/security-alerts/cpuoct2026.html; the provided data does not specify an exact patched version, so confirm the applicable EBS 12.2.3-12.2.15 patch in the CPU before deployment (patch available per vendor advisory). If patching must be delayed, reduce exposure by blocking direct internet access to EBS Application Object Library HTTP endpoints and requiring VPN or zero-trust access for legitimate users (trade-off: reduced remote usability), and monitor for anomalous create/delete/modify or read activity in the component. Because exploitation requires victim interaction, prioritize user reporting of suspicious links and unexpected application prompts, and restrict privileged data-modification rights to least privilege (trade-off: operational overhead).

Technical ContextAI · show details

The affected technology is Oracle E-Business Suite's Application Object Library (Core), an application-layer component reachable over HTTP. The supplied CVSS vector confirms network reachability without authentication (AV:N/PR:N), but also mandates user interaction (UI:R) and high attack complexity (AC:H), meaning an attacker cannot complete the attack alone and must overcome additional timing or configuration dependencies. Impact is confined to confidentiality and integrity (C:H/I:H/A:N) with scope unchanged (S:U); the input lists CWE as N/A, so the root-cause weakness class is not classified in the available data. Oracle's advisory and EUVD-2026-106098 list E-Business Suite/Application Object Library 12.2.3 through 12.2.15 as affected, and the 'Authentication Bypass' tag is consistent with the PR:N vector.

DescriptionCVE.org

Vulnerability in the Oracle Application Object Library product of Oracle E-Business Suite (component: Core). Supported versions that are affected are 12.2.3-12.2.15. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Application Object Library. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Application Object Library accessible data as well as unauthorized access to critical data or complete access to all Oracle Application Object Library accessible data. CVSS 3.1 Base Score 6.8 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N).
