Vulnerability Assessment

Exploitation Conditions

Exploitation requires network access to the Oracle Enterprise Manager Base Platform's Agent Next Gen component over HTTP and a valid low-privileged authenticated account (CVSS PR:L) - it is not unauthenticated. No user interaction is required (UI:N) and attack complexity is low (AC:L), so once an attacker holds any low-privilege credential and can reach the HTTP interface, exploitation is straightforward against affected versions 13.5 and 24.1. The primary limiting factors are the need for prior authentication and network reachability of the OEM HTTP interface; environments that restrict the management console to trusted administrative networks and tightly control low-privilege accounts materially reduce exposure.

Impact

This is a genuine high-priority vulnerability, not an inflated-CVSS artifact. The vendor-supplied CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, score 8.8) is internally consistent with the description: network-reachable over HTTP, low attack complexity, and only low privileges required, yielding full compromise ('takeover') of the Oracle Enterprise Manager Base Platform. Because PR:L is present, exploitation requires an authenticated low-privileged account rather than being fully unauthenticated, which is the single most important mitigating factor. No EPSS score, CISA KEV listing, or public POC is present in the provided intelligence, so there is no evidence of active exploitation or weaponization - the risk is driven by the ease of exploitation and the severity of impact rather than by observed in-the-wild activity. One data tension to verify: the input Tags label this 'Information Disclosure', yet the CVSS vector and description indicate full confidentiality, integrity, and availability compromise (complete takeover), so the tag understates true impact. Priority should be high for any OEM operator exposing the console/agent to networks where low-privileged accounts exist, but absence of EPSS/KEV/POC means this is a patch-promptly rather than drop-everything emergency.

Exploit ScenarioDerived

An attacker who already holds a low-privileged account on an Oracle Enterprise Manager deployment sends crafted HTTP requests to the Agent Next Gen component over the network. Because attack complexity is low and no user interaction is needed, the request escalates the attacker's control into a full takeover of the Oracle Enterprise Manager Base Platform. No public exploit code is identified at the time of analysis, so this scenario is inferred from the CVSS vector rather than from a published POC.

AnalysisAIv1 – Oct 21, 2026

Authenticated low-privileged attackers can take over Oracle Enterprise Manager Base Platform 13.5 and 24.1 through the Agent Next Gen component over HTTP. The flaw is easily exploitable (CVSS 8.8, AC:L/UI:N) once any low-privilege account is obtained and the management interface is reachable, with high confidentiality, integrity, and availability impact. No public exploit was identified at time of analysis, and Oracle's October 2026 Critical Patch Update advisory is the remediation reference.

RemediationAI

Apply the Oracle Critical Patch Update October 2026 fix for Oracle Enterprise Manager Base Platform 13.5 and 24.1 (advisory: https://www.oracle.com/security-alerts/cpuoct2026.html). Until patched, restrict HTTP reachability of the OEM management and Agent Next Gen interfaces to trusted administrative networks via firewall allowlists; the trade-off is that this can block legitimate agent or console traffic and requires an accurate source inventory. Reduce exposure by inventorying and limiting low-privileged accounts that can authenticate to OEM, and monitor for anomalous authenticated requests to Agent Next Gen endpoints. No public exploit was identified at time of analysis, but the low attack complexity means credential hygiene and network segmentation are the key compensating controls.

Technical ContextAI · show details

Oracle Enterprise Manager Base Platform is Oracle's infrastructure management console, and the affected Agent Next Gen component handles agent lifecycle and communication functions exposed over HTTP. The CVSS vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H indicates a network-reachable, low-complexity issue that requires a valid low-privileged account but no user interaction; successful exploitation yields full takeover of the Base Platform with high confidentiality, integrity, and availability impact. No CWE was supplied, so the precise root-cause class (for example, authorization bypass, injection, or unsafe deserialization) cannot be confirmed from the available data; EUVD and Oracle both identify the same two supported branches, 13.5 and 24.1, as affected.

DescriptionNVD

Vulnerability in the Oracle Enterprise Manager Base Platform product of Oracle Enterprise Manager (component: Agent Next Gen). Supported versions that are affected are 13.5 and 24.1. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Enterprise Manager Base Platform. Successful attacks of this vulnerability can result in takeover of Oracle Enterprise Manager Base Platform. CVSS 3.1 Base Score 8.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

Executive ViewAI

Why It Matters

Oracle Enterprise Manager Base Platform 13.5 and 24.1 are exposed to a high-severity flaw in the Agent Next Gen component that, once a low-privilege account is obtained and the management interface is reachable, could let an attacker take over the platform with broad confidentiality, integrity, and availability impact. Because no public exploit was identified at time of analysis and no vendor-released patch is available, leadership should prioritize reducing exposure of the management interface and controlling low-privilege access until Oracle's October 2026 Critical Patch Update is available.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Restrict network access to Oracle Enterprise Manager Base Platform 13.5 and 24.1 management interfaces, enforce least privilege and strong authentication for low-privilege accounts, monitor Agent Next Gen logs for anomalous activity, and apply Oracle's October 2026 Critical Patch Update when available.
