Exploitation Conditions

Exploitation requires human interaction from a person other than the attacker (CVSS UI:R) - a user of Oracle Customer Care must be induced to open attacker-supplied content, so this cannot be driven autonomously. No authentication is required of the attacker (PR:N), and the vector is remote over HTTP (AV:N/AC:L). Affected deployments are Oracle E-Business Suite Customer Care versions 12.2.3 through 12.2.15; the scope change (S:C) means successful injection may reach additional EBS products accessible to the victim. The primary limiting factors are the mandatory victim interaction and the partial (Low) confidentiality/integrity impact with no availability impact.

Impact

This is a moderate-severity issue (CVSS 3.1 base 6.1) whose vector - AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N - is the textbook pattern Oracle assigns to reflected cross-site scripting (XSS): network-reachable, low complexity, no privileges, but requiring victim interaction (UI:R), with a scope change (S:C) and only Low confidentiality and integrity impact and no availability impact. Despite the 'Authentication Bypass' tag in the input, nothing in the description or the CVSS metrics supports an authentication-bypass characterization - the C:L/I:L/A:N + UI:R + S:C combination indicates client-side script injection, not a direct backend auth bypass, so that tag appears mislabeled and should not drive prioritization. No EPSS score, no CISA KEV listing, and no public POC were provided, so real-world exploitation signals are absent. The mandatory human interaction (an administrator or user must be lured into clicking/opening attacker-controlled content) and the merely partial (Low) impact meaningfully reduce real-world risk versus a true unauthenticated RCE; this is a patch-in-normal-cycle item rather than an emergency. Note the limitation: risk assessment rests solely on the Oracle CPU description and the CVSS vector, with no independent exploitation telemetry available.

Exploit ScenarioDerived

An attacker crafts a malicious link or payload targeting the Oracle Customer Care (Internal Operations) component and lures an authenticated EBS user into opening it; the injected script executes in the victim's session, and because of the scope change it can affect other Oracle E-Business Suite products the user can reach, enabling limited unauthorized read and limited update/insert/delete of data. No public exploit code was identified at time of analysis, and the attack cannot succeed without that human interaction.

AnalysisAIv1 – Oct 21, 2026

Reflected cross-site scripting (XSS) is the assessed weakness in Oracle Customer Care within Oracle E-Business Suite 12.2.3 through 12.2.15, where an unauthenticated remote attacker can use HTTP to induce a victim user to open attacker-supplied content and cause limited unauthorized reads or updates in Customer Care and, through scope change, potentially affect other EBS products available to that user. The CVSS 3.1 base score is 6.1, exploitation requires human interaction, and confidentiality/integrity impact is Low with no availability impact; no public exploit identified at time of analysis.

RemediationAI

Patch available per vendor advisory: apply the Oracle E-Business Suite Customer Care fixes in Oracle's October 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpuoct2026.html); the available data does not provide an exact patched version number, so confirm the applicable EBS patch level with Oracle support. Until patched, reduce exposure by restricting network access to Customer Care HTTP endpoints to trusted users and networks (trade-off: limits remote access), deploying WAF or reverse-proxy rules to detect and block reflected script payloads against Customer Care URLs (trade-off: possible false positives and maintenance overhead), and reinforcing user awareness about not following unsolicited links or opening untrusted content in authenticated sessions (trade-off: user-dependent and not a technical control). No public exploit identified at time of analysis.

Technical ContextAI · show details

Oracle E-Business Suite is Oracle's integrated enterprise resource planning and customer relationship management application suite, and Customer Care is the CRM/customer-service module; the affected Internal Operations component is reached over HTTP. The assessed CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) is consistent with reflected cross-site scripting: no attacker authentication is required, but a victim other than the attacker must interact with crafted content, and the scope change indicates code or content can affect resources beyond the vulnerable component, such as other EBS products available in the victim's session. No CWE identifier was supplied, and no CPE strings were provided; the root-cause class reflected by the vector is client-side script injection/reflected XSS rather than server-side code execution. Impact is limited to Low confidentiality and integrity, with no availability effect.

DescriptionCVE.org

Vulnerability in the Oracle Customer Care 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 Customer Care. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Customer Care, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Customer Care accessible data as well as unauthorized read access to a subset of Oracle Customer Care accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).
