Exploitation Conditions

Exploitation requires network reachability to the Agent Next Gen SSH interface on an Oracle Enterprise Manager Base Platform 13.5 or 24.1 host, plus possession of a low-privileged credential accepted by that SSH path (PR:L per Oracle's CVSS). No user interaction is required (UI:N) and attack complexity is low (AC:L), and Oracle characterizes the bug as 'easily exploitable.' Limiting factors that reduce realistic exposure: the attacker must already hold valid low-privileged credentials, the agent's SSH surface is typically reachable only from the OMS or admin networks in well-segmented deployments, and only the named versions 13.5 and 24.1 are confirmed affected.

Impact

Signals are mixed-but-actionable: CVSS 3.1 is 8.8 with AV:N/AC:L/PR:L/UI:N and full C/I/A impact, and Oracle explicitly labels it 'easily exploitable,' which together justify prioritization for any environment running OEM 13.5 or 24.1. Countervailing signals are notable - there is no CISA KEV listing, no EPSS score provided in the input, no public POC observed, and no CWE assignment, which suggests targeted/credentialed risk rather than mass exploitation. The CVSS vector says AV:N but the description constrains the path to 'network access via SSH,' which in many OEM deployments means the agent's SSH surface is reachable only from the OMS or jump hosts; defenders whose Agent Next Gen SSH is not broadly reachable should treat realistic exploitability as lower than the raw 8.8 implies, while defenders exposing OEM management networks broadly should treat it as urgent.

Exploit ScenarioDerived

An attacker who has obtained any low-privileged credential usable against the Agent Next Gen SSH surface - for example a service account harvested from a compromised DBA workstation or a weak operator account on a monitored host - connects over the network to a vulnerable OEM agent and triggers the flaw to escalate into full control of the Oracle Enterprise Manager Base Platform. From there they can pivot to any Oracle target managed by OEM, exfiltrate database credentials stored in the management framework, and disrupt monitoring across the estate. No public POC has been observed at time of analysis.

AnalysisAIv1 – Jun 16, 2026

Authenticated takeover of Oracle Enterprise Manager Base Platform 13.5 and 24.1 is possible via the Agent Next Gen component, where a low-privileged attacker with SSH network access can fully compromise confidentiality, integrity, and availability. Oracle rates this 8.8 and describes it as easily exploitable, but no public exploit identified at time of analysis and the flaw is not listed in CISA KEV. The single source is Oracle's June 2026 Critical Patch Update advisory, which is the authoritative reference for affected versions and fixes.

RemediationAI

Apply the patches from Oracle's June 2026 Critical Patch Update for Oracle Enterprise Manager Base Platform 13.5 and 24.1 as published at https://www.oracle.com/security-alerts/cspujun2026.html - Oracle CPU patches are the only vendor-released fix and exact patch identifiers should be retrieved from the CPU matrix in that advisory. Until patches are deployed, restrict network reachability to the Agent Next Gen SSH listener so it is only accessible from the OMS and authorized administrator jump hosts (firewall ACLs or host-based controls), rotate and tightly scope any low-privileged OEM/agent credentials that could satisfy the PR:L requirement, and monitor SSH authentication logs on agent hosts for anomalous logins from non-OMS sources. Note that locking down SSH to the agent may break ad-hoc administrative workflows that rely on direct agent access, so coordinate with DBA teams before tightening.

Technical ContextAI · show details

Oracle Enterprise Manager Base Platform is the core management framework for monitoring and administering Oracle databases, middleware, and engineered systems across enterprise estates. The vulnerable component, Agent Next Gen, is the management agent that runs on monitored hosts and communicates back to the OMS (Oracle Management Server), typically over secured channels. The advisory specifies SSH as the attack vector, indicating the weakness involves the agent's SSH-based remote command, file transfer, or management protocol surface rather than the HTTPS upload receiver. No CWE was assigned in the input, so the precise root-cause class (authentication bypass, command injection, privilege escalation in agent dispatch, etc.) cannot be determined from the available data, but the H/H/H impact combined with PR:L points to a privilege escalation or authorization flaw reachable by any holder of a low-privileged OEM/SSH credential.

DescriptionCVE.org

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 SSH 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

Critical vulnerability in Oracle Enterprise Manager Base Platform versions 13.5 and 24.1 enables authenticated users with SSH access to seize complete control of the platform, directly threatening operational visibility and management capabilities across enterprise IT infrastructure. While no public exploit code has been identified, the lack of available patches combined with high exploitability makes this an urgent priority for organizations using affected versions.

Business Impact: Severe
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: Restrict SSH access to Enterprise Manager systems to trusted administrative networks via firewall rules; require multi-factor authentication for all SSH access; implement enhanced monitoring and alerting for authentication anomalies and privilege escalation attempts; disable Agent Next Gen component if operationally feasible; segment Enterprise Manager systems from critical production infrastructure; implement host-based firewall rules and sudo restrictions to limit local privilege escalation.
