Oracle Enterprise Manager Agent Next Gen Takeover Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-46994

The vulnerability affects the Oracle Enterprise Manager Base Platform, a management component that often requires network accessibility for agent communication. Because the attack vector is network-based and allows unauthenticated access via HTTPS, it is commonly deployed in a manner that may be reachable across network segments or edge environments.

Frequently asked questions

What is the Oracle Enterprise Manager Base Platform?

It is a centralized management framework used by organizations to monitor, manage, and automate their IT infrastructure, databases, and middleware. The Agent Next Gen component specifically handles communication between the central management server and the distributed systems it oversees, acting as a critical bridge for collecting performance data and executing administrative tasks across a managed environment.

What does this CVE-2026-46994 vulnerability actually mean?

This vulnerability represents a critical flaw that allows an attacker to bypass security controls entirely. It essentially means the software fails to verify the identity of a connection request before granting access. By exploiting this, an unauthorized actor could potentially gain full control over the management platform, allowing them to manipulate system data or disrupt the operations of the entire infrastructure that the platform manages.

How can an attacker trigger this vulnerability?

An attacker exploits this by sending specially crafted HTTPS requests directly to the Agent Next Gen component. Because the system requires no authentication, the attacker does not need a username or password to initiate the exploit. Importantly, this does not trigger from local, non-networked interactions; it specifically requires the attacker to have network reachability to the HTTPS service provided by the affected component.

Is my system at risk if it is not on the public internet?

Halo Surface Signal indicates that because this vulnerability relies on network access via HTTPS, it is most dangerous when reachable across network segments. While being off the public internet reduces exposure to global actors, any internal network path—such as a connection from a compromised workstation or a misconfigured internal firewall—could still allow an attacker to reach the vulnerable agent and compromise your management platform.

What should I do first to address this?

Begin by auditing your infrastructure to locate all instances of Oracle Enterprise Manager Base Platform version 13.5 or 24.1. Once identified, map out which segments can reach these components over the network. Prioritize securing these connections by restricting network access to only trusted sources, and coordinate with your vendor to apply the necessary official updates to patch the underlying Agent Next Gen component.
