Vulnerability AssessmentAI

Exploitation Attacker must reach the Oracle Management Server HTTPS interface and hold a low-privileged Enterprise Manager account (PR:L) on a deployment running Base Platform 13.5 or 24.1 with the Metadata Plugin component active - which is the default in supported EM installations. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Signals are uniformly severe: CVSS 9.9 with AV:N/AC:L/PR:L/UI:N/S:C and H/H/H impacts indicates an easily exploitable, low-privilege, network-reachable flaw whose blast radius extends past EM itself into the Oracle estate it manages. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained any low-privileged EM account - for example, a read-only operator credential harvested through phishing or credential reuse - connects to the OMS over HTTPS and abuses the Metadata Plugin component to escalate to full takeover of the EM platform. From that foothold, the attacker leverages EM's agent connectivity and stored credentials to pivot into managed Oracle databases and middleware (the scope-change impact). …
Remediation Apply Patch available per vendor advisory by installing the fixes for Oracle Enterprise Manager Base Platform 13.5 and 24.1 delivered in the Oracle Critical Patch Update of June 2026 (https://www.oracle.com/security-alerts/cspujun2026.html); exact patched build numbers should be taken directly from the CPU matrix as Oracle releases bundle patches per platform. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Identify and inventory all Oracle EM Base Platform deployments (13.5 and 24.1 specifically) and assess network exposure. …
