DescriptionCVE.org

Vulnerability in the Oracle Enterprise Manager Base Platform product of Oracle Enterprise Manager (component: Metadata Plugin). Supported versions that are affected are 13.5 and 24.1. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Enterprise Manager Base Platform. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Enterprise Manager Base Platform, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Enterprise Manager Base Platform. CVSS 3.1 Base Score 9.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H).

AnalysisAI

Cross-scope takeover of Oracle Enterprise Manager Base Platform 13.5 and 24.1 allows unauthenticated remote attackers to fully compromise the management platform - and potentially additional managed products - by tricking an authenticated user into interacting with a malicious HTTP-delivered payload targeting the Metadata Plugin component. The CVSS 3.1 base score is 9.6 with a scope change reflecting impact beyond the vulnerable component, and at time of analysis no public exploit identified at time of analysis. …

Access

Impact

Vulnerability AssessmentAI

Exploitation Exploitation requires (1) network HTTP/HTTPS reach to the targeted OEM Base Platform 13.5 or 24.1 instance - typically a management network rather than the public internet - and (2) interaction (UI:R) from a different, already-authenticated OEM user (an administrator clicking a link, loading a page, or importing attacker-supplied metadata into the Metadata Plugin). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine high-priority issue rather than an inflated CVSS number. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker hosts a malicious page or sends a crafted link to an OEM administrator; when the administrator - already authenticated to the OEM console - visits the link or loads attacker-supplied metadata, the Metadata Plugin processes the payload and performs privileged actions in the administrator's session, resulting in full takeover of the OEM platform and, via scope change, follow-on impact to the Oracle databases and middleware managed by that OEM instance. No public exploit identified at time of analysis, but the low complexity and unauthenticated network vector make POC development plausible once details are reverse-engineered from the patch.
Remediation Apply the fixes shipped in the Oracle Critical Patch Update of June 2026 (cspujun2026) to OEM Base Platform 13.5 and 24.1 as soon as a maintenance window allows; exact patch bundle identifiers are listed in the advisory at https://www.oracle.com/security-alerts/cspujun2026.html - patch available per vendor advisory, no standalone fixed build number is specified in the input. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

24 hours: Identify all Oracle Enterprise Manager Base Platform installations (13.5 and 24.1); restrict network access to the console to internal networks only; disable remote/internet-facing access if possible; alert security teams and administrators to the phishing/social engineering vector. …
