The vulnerability affects the Identity Manager Connector, which is typically used for internal identity lifecycle management and integration between systems. It requires network access via SSH, a protocol generally restricted to internal administrative use and rarely exposed directly to the public internet in common, secure deployment patterns.

Horizon Alert

Summary of the vulnerability and why it matters

A vulnerability has been identified in Oracle Fusion Middleware's Identity Manager Connector, specifically impacting its Generic Unix Connector. This issue, if exploited, could allow a low-privileged attacker with network access via SSH to gain complete control over the Identity Manager Connector, potentially affecting other integrated products. The high CVSS score of 9.9 indicates critical impacts to confidentiality, integrity, and availability.

  • A connector flaw allows unauthorized system control.
  • Focus on confirming relevance and exposure internally.
  • Understand potential access risks to identity management.

Attack Path

How an attacker could exploit the issue

An attacker with low privileges could exploit this vulnerability by accessing the Identity Manager Connector over the network via SSH. This could lead to a complete takeover of the connector, potentially impacting other Oracle Fusion Middleware products.

  • Network access via SSH required.
  • Low-privileged attacker triggers vulnerability.
  • Complete takeover of connector and other products.

Live Threat

Current exploitation, exposure, and threat context

A low-privileged attacker with network access via SSH could compromise the Identity Manager Connector, potentially leading to a complete takeover of the connector. This compromise could also impact other connected products, affecting confidentiality, integrity, and availability of services when supported.

  • Identity Manager Connector could be taken over.
  • Attacker with network access via SSH.
  • Service takeover and impact on other products.

Operational Fix

Recommended remediation, mitigation, and detection steps

The Identity Manager Connector, part of Oracle Fusion Middleware, is likely managed by application owners and the infrastructure or platform teams responsible for identity and access management. The initial step is to pinpoint all instances of the affected connector, assess their exposure and criticality, identify the specific accountable owner for each, and then prioritize remediation efforts based on potential business impact.

  • Identify accountable application or platform owners.
  • Verify affected connector reachability and criticality.
  • Plan targeted remediation based on risk.

Frequently asked questions

What is the Oracle Identity Manager Connector?

It is a specialized component within Oracle Fusion Middleware designed to automate user identity lifecycle tasks. Specifically, the Generic Unix Connector facilitates communication between the identity management platform and Unix-based systems, enabling organizations to centrally manage access rights, provision accounts, and synchronize user data across their IT infrastructure.

What does CVE-2026-46794 mean for security?

This vulnerability is classified as Improper Privilege Management (CWE-269). It means the connector fails to properly restrict or verify the authority of a user. An attacker with minimal existing access can leverage this weakness to gain administrative control over the connector, effectively bypassing security controls to gain full command of the component.

How is this vulnerability triggered?

An attacker must have network-level access to the Identity Manager Connector via SSH to initiate an exploit. Simply interacting with the application interface or web console does not trigger this specific flaw; it requires establishing a connection through the SSH protocol used by the Generic Unix Connector.

Is my environment at risk from this CVE?

According to Halo Surface Signal, risk is considered unlikely for most because the Identity Manager Connector handles internal identity integration and typically relies on SSH for administrative tasks, which are rarely exposed to the public internet. You should verify if any connector instances are inadvertently reachable over untrusted networks.

What should I do if I use this software?

Begin by auditing your infrastructure to create an inventory of all Identity Manager Connector deployments. Once located, confirm which teams manage these instances and evaluate whether they are accessible via internal network segments or exposed externally. Prioritize the application of official vendor security updates to mitigate the risk of unauthorized takeover.
