Control-M/Server Command Injection Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.5)

CVE-2026-10539

Control-M/Server is typically deployed as a backend job scheduling and automation platform within internal corporate data centers or private network segments. While network-reachable within the infrastructure, it is not designed to be exposed directly to the public internet, and such exposure would be considered an unusual configuration.

Horizon Alert

Summary of the vulnerability and why it matters

A security vulnerability has been identified in Control-M/Server, a job scheduling and automation platform. This issue involves how the system handles commands, and if exploited, could allow unauthorized individuals to run commands on the server, potentially leading to a compromise.

  • Flaw lets attackers run commands on servers.
  • Critical for understanding potential internal risk.
  • Confirm relevance and any internal exposure.

Attack Path

How an attacker could exploit the issue

An unauthenticated attacker could exploit a flaw in Control-M/Server's communication to execute unauthorized commands. This occurs because the server does not properly filter user input in its command processing, allowing an attacker to potentially gain control of the server.

  • No authentication required.
  • Vulnerable command input handling.
  • Risk of unauthorized command execution.

Live Threat

Current exploitation, exposure, and threat context

An unauthenticated attacker could execute unauthorized commands on the Control-M/Server when specific conditions are met, potentially leading to a compromise of the server. This occurs because the communication command does not sufficiently filter or sanitize user-supplied input.

  • Server commands and data could be affected.
  • Commands could be injected via network.
  • Unauthorized command execution is possible.

Operational Fix

Recommended remediation, mitigation, and detection steps

Action will likely fall to the Control-M administrators and the infrastructure or platform teams responsible for the Control-M/Server environment. The first practical step is to identify all Control-M/Server instances, confirm their network exposure and business criticality, and then engage the system owners for a risk-based remediation plan, coordinating with BMC if necessary.

  • Control-M administrators and platform teams own this.
  • Verify Control-M/Server reachability and criticality.
  • Plan remediation based on identified risks.

Frequently asked questions

What is Control-M/Server used for?

Control-M/Server is a core platform used by organizations to automate and manage complex job scheduling across their IT infrastructure. It serves as a central engine that orchestrates workflows, batch processing, and data movement, ensuring that critical business tasks run in the correct sequence and on schedule across various systems.

What does CWE-305 mean for CVE-2026-10539?

The vulnerability involves improper input validation in command processing. Specifically, CWE-305 indicates that the system fails to correctly handle authentication or authorization requirements for certain commands. In the context of this CVE, this weakness allows an unauthenticated user to submit inputs that the server fails to sanitize, potentially enabling the unauthorized execution of system commands.

How does an attacker trigger this command injection?

An attacker triggers this flaw by sending specifically crafted input through the server's communication channels. Because the server does not filter this input, it interprets the data as a command to be executed. The vulnerability is not triggered by standard, legitimate job scheduling traffic; it requires specific, malicious input patterns designed to bypass the server's command-processing security.

Is my Control-M/Server instance at high risk?

According to Halo Surface Signal, this software is typically meant for internal data centers and is not designed to be public-facing. While the vulnerability exists regardless of location, the risk is significantly higher if your instance is incorrectly exposed to the internet. Internal instances are generally safer, but they remain at risk if an attacker has already gained access to your private network.

What are the first steps to address this?

Begin by auditing your infrastructure to create a complete inventory of all Control-M/Server instances. Verify the network configuration for each to determine if they are accessible from outside your internal network. Once identified, prioritize the most critical systems and consult the official BMC documentation to coordinate risk-based remediation or patching with your platform teams.
