Exploitation Conditions

Exploitation requires the attacker to already have logon access to the infrastructure/host where Oracle E-Business Suite Applications DBA (AD Utilities component) executes - this is a local vector (AV:L), not remote network reach, which is the primary limiting factor. Additionally, successful attacks require human interaction from a person other than the attacker (UI:R), meaning a separate privileged user (such as a DBA or operator) must perform an action (e.g., invoke the affected AD Utilities operation) for the attack to succeed. No prior authentication to the EBS application itself is required (PR:N). Affected deployments are limited to EBS versions 12.2.3 through 12.2.15 running the Applications DBA product; environments outside this range or without local multi-user access to the EBS host are not exposed.

Impact

This is a genuine but second-tier priority rather than a drop-everything emergency. The CVSS 3.1 base score of 7.8 (HIGH) is driven by full technical impact (C:H/I:H/A:H, resulting in takeover of Applications DBA) and low attack complexity (AC:L), but it is significantly tempered by two gating metrics: AV:L means the attacker must already have local logon access to the host where Applications DBA runs (not remote/network reach), and UI:R means successful attacks require human interaction from a person other than the attacker (e.g., a DBA/operator). PR:N indicates no prior authentication to the application itself is needed, but this is not the same as remote-unauthenticated reach - the local-access prerequisite is the real limiter. No EPSS score was provided in the input, so exploitation probability cannot be quantified. The CVE is NOT listed in CISA KEV and no public exploit code was provided, so exploitation status is 'no public exploit identified at time of analysis.' There is no conflict between the CVSS vector and the description - both consistently describe a local-access, user-interaction-dependent flaw. Net: the combination of required local foothold plus required victim interaction makes mass/automated exploitation unlikely, placing this below network-facing unauthenticated EBS flaws in urgency, though it remains a legitimate privilege/takeover risk in multi-user or shared EBS infrastructure.

Exploit ScenarioDerived

An attacker who already holds a low-level local account (or shell) on the server running Oracle E-Business Suite Applications DBA plants or manipulates AD Utilities content, then waits for or socially engineers a DBA/operator into running the affected utility. When that privileged person interacts with the crafted input, the attacker gains full control (confidentiality, integrity, and availability) over Applications DBA. No public proof-of-concept exploit was identified at the time of analysis.

AnalysisAIv1 – Oct 21, 2026

Local compromise of the Applications DBA (AD Utilities) component in Oracle E-Business Suite 12.2.3 through 12.2.15 can let an attacker who already has logon access to the EBS host seize control of the Applications DBA component, with high confidentiality, integrity and availability impact (CVSS 3.1 base score 7.8). No authentication to the E-Business Suite application itself is needed (PR:N), but the attack is local (AV:L) and requires a separate privileged user such as a DBA to perform an action (UI:R), so the practical exposure is limited to hosts with multi-user interactive access. There is no public exploit identified at time of analysis and the issue is not in CISA KEV; no EPSS score was supplied in the available data.

RemediationAI

Primary fix: apply the Oracle Critical Patch Update for October 2026 to E-Business Suite Applications DBA on all instances at versions 12.2.3 through 12.2.15, following the patch/mitigation instructions in https://www.oracle.com/security-alerts/cpuoct2026.html - the input data does not state an exact patched version number, so treat the CPU advisory as the authoritative source rather than assuming a build. Because the vector is local (AV:L) and depends on a second user's interaction (UI:R), the highest-value compensating control while patching is to restrict interactive logon to the EBS application-tier host that runs AD Utilities to a small, named set of DBA and operations accounts, removing shell/console access for general application users and service accounts; the trade-off is reduced operational flexibility for support staff and possible friction in break-glass procedures. Enforce least privilege and command-level auditing (including sudo/privileged command logging) on the AD Utilities executables so that any invocation is attributable to a specific operator, accepting the added log volume and modest performance overhead. Where AD Utilities administrative actions are only occasionally required, consider disabling or tightly scheduling access to those utilities outside maintenance windows, with the trade-off that emergency patching or recovery work must go through an approval step. Monitor for unexpected local logons or AD Utilities invocations correlated to the UI:R precondition, and verify EBS host hardening (file permissions, shared-account elimination) as an interim measure; none of these controls substitute for applying the CPU patch.

Technical ContextAI · show details

The affected product is the Applications DBA utilities (AD Utilities) shipped with Oracle E-Business Suite - the administrative toolset DBAs use to patch, configure and maintain the EBS application tier - running on supported EBS releases 12.2.3 through 12.2.15. The CVSS 3.1 vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H describes a locally reachable, low-complexity attack that needs no credentials (PR:N) but depends on a second party taking an action (UI:R), and stays within a single security scope while fully compromising confidentiality, integrity and availability. No CWE identifier was published by the reporter, so the root-cause class (for example unsafe file/permission handling or insufficient validation in an administrative utility) cannot be confirmed from the available data; the defining weakness is that the AD Utilities component implicitly trusts the local execution context of whoever can reach the EBS infrastructure. Because the vector is local rather than network (AV:L), internet-facing exposure alone does not make a system exploitable - the attacker must first obtain logon access to the host where Applications DBA executes.

DescriptionCVE.org

Vulnerability in the Applications DBA product of Oracle E-Business Suite (component: AD Utilities). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows unauthenticated attacker with logon to the infrastructure where Applications DBA executes to compromise Applications DBA. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of Applications DBA. CVSS 3.1 Base Score 7.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

Executive ViewAI

Why It Matters

Oracle E-Business Suite 12.2.3 through 12.2.15 contains a high-severity local privilege issue in its Applications DBA utilities that could let someone with host access take control of a privileged administrative component, compromising confidentiality, integrity, and availability of ERP data. Leadership should care because EBS often underpins finance and operations, and no vendor-released patch is available at time of analysis, so exposure must be managed through host access controls, least privilege, and monitoring until Oracle provides a fix.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations include restricting interactive host logon and DBA privileges to named administrators, enforcing least privilege and separation of duties, removing unnecessary local and shared accounts, auditing AD Utilities activity, monitoring Oracle advisories, and segmenting or enhancing monitoring for high-value EBS hosts.
