Vulnerability Assessment

Exploitation Conditions

Exploitation requires network access over HTTP to the Oracle Enterprise Manager Base Platform console and a valid low-privileged account on that platform (CVSS PR:L) - it is NOT remotely exploitable by an unauthenticated attacker. The specific affected feature is the Metadata Plugin component on supported versions 13.5 and 24.1. Limiting factors: the attacker must first obtain authenticated access to Enterprise Manager; impact is confined to unauthorized read access to a subset of accessible data (no integrity or availability impact), and no user interaction by a victim is needed (UI:N).

Impact

This is a genuinely moderate-to-low real-world risk, and the signals are consistent rather than conflicting. The CVSS 3.1 base score of 4.3 (MEDIUM) is driven by a network attack vector (AV:N) with low complexity (AC:L) and no user interaction (UI:N), but it is tempered by two important limiters: the attacker must already hold low-level privileges (PR:L) and the only impact is partial confidentiality loss (C:L, with I:N/A:N) - unauthorized read access to a subset of data, no write and no availability impact. No EPSS score, CISA KEV listing, or public POC was provided in the intelligence set, so there is no evidence of active exploitation or weaponization; exploitation status is 'no public exploit identified at time of analysis.' There is a conflict in the input metadata worth flagging: the 'Authentication Bypass' tag directly contradicts the Oracle description and CVSS vector, which require an authenticated low-privileged attacker (PR:L) and describe an information-disclosure flaw, not an auth bypass - this tag appears mislabeled and should not drive prioritization. Overall this is a lower-tier Oracle CPU item: patch in routine cycles rather than as an emergency, prioritized above purely local issues but below unauthenticated RCE.

Exploit ScenarioDerived

A user with an existing low-privileged account on the Oracle Enterprise Manager Base Platform sends a crafted HTTP request to the vulnerable Metadata Plugin component and retrieves a subset of data they are not authorized to read. No public exploit code is identified at time of analysis, and because privileges are required (PR:L), the attacker needs valid credentials or an existing foothold on the management console.

AnalysisAIv1 – Oct 21, 2026

Low-privileged authenticated users of Oracle Enterprise Manager Base Platform 13.5 and 24.1 can read a limited subset of platform data through the Metadata Plugin component exposed over HTTP (CVSS 3.1 score 4.3). Exploitation requires a valid low-privileged Enterprise Manager account and network reachability to the console, so this is not an unauthenticated attack, and impact is confined to confidentiality. No public exploit code or confirmed active exploitation (CISA KEV) was identified at time of analysis.

RemediationAI

Apply the Oracle Critical Patch Update October 2026 fixes for Enterprise Manager Base Platform 13.5 and 24.1 as published at https://www.oracle.com/security-alerts/cpuoct2026.html; Oracle CPUs are cumulative, so deploy the latest CPU applicable to your release. Patch availability is per the vendor advisory, and no exact patched build number is confirmed in the input. If patching must be deferred, restrict HTTP access to the EM console and Metadata Plugin endpoints to trusted administrative networks using firewall ACLs or a reverse proxy (trade-off: may break legitimate console users and integrations), review and minimize low-privileged EM accounts to limit exposure (trade-off: reduced operational access for monitoring staff), and monitor console access logs for anomalous metadata reads; disabling unused metadata plugin features can reduce attack surface at the cost of losing metadata collection.

Technical ContextAI · show details

Oracle Enterprise Manager Base Platform is Oracle's on-premises management console used to monitor and administer Oracle estates; the Metadata Plugin component handles metadata registration and collection surfaced through the console's HTTP interface. The assessed vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N describes a network-reachable authorization weakness in which an authenticated low-privileged user can bypass intended access boundaries to read a subset of accessible data, with no integrity or availability impact and no victim interaction. Although the source tags mention 'Authentication Bypass', the PR:L metric and Oracle's description indicate the flaw is post-authentication access control, not a pre-auth bypass. No CWE was provided, and no CPE strings were supplied; EUVD and Oracle both list EM Base Platform 13.5 and 24.1 as affected.
