Termix File Manager Command Injection

CVE advisorySeverity: CRITICAL (CVSS 9.0)

CVE-2026-45750

Termix is a web-based server management platform designed to provide remote access and administrative capabilities. Such tools are commonly deployed as internet-facing management gateways or portals to facilitate remote terminal and file system access, making them frequently reachable from the public internet in standard deployment patterns.

Horizon Alert

Summary of the vulnerability and why it matters

A vulnerability in the Termix file manager could allow an attacker to execute commands on your servers through a web interface. This issue arises from how the platform handles file path information when communicating with servers via SSH.

Command execution via web interface.
Remote servers could be compromised.
Confirm relevance and assess exposure.

Attack Path

How an attacker could exploit the issue

An attacker with limited privileges could target the Termix File Manager component. By providing specially crafted input to the `resolvePath` function, an attacker could inject commands into an active SSH session. This vulnerability allows for remote code execution on the server, potentially leading to a full compromise of the system.

Requires authenticated access.
Injects commands via path parameter.
Leads to remote code execution.

Live Threat

Current exploitation, exposure, and threat context

The Termix File Manager component, when running a version prior to 2.3.2, could allow an attacker to execute arbitrary shell commands on the remote server via an active SSH session. This could occur when a user interacts with the file manager, and the path parameter is processed insecurely, enabling shell command substitution syntax to be interpreted by the remote shell.

Server-side commands could be executed.
Path parameter in file manager requests.
Compromise of server, data access, and actions.

Operational Fix

Recommended remediation, mitigation, and detection steps

System owners and platform teams are likely responsible for managing Termix, a web-based server management platform. The first practical step is to identify all instances of Termix, assess their reachability and business criticality, and locate the accountable owner for each. Remediation planning should then be risk-based, coordinating with vendors if necessary and considering maintenance windows.

Platform and system owners should address.
Verify Termix reachability and criticality.
Plan risk-based remediation.

Frequently asked questions

What is Termix and what is it used for?

Termix is a web-based management platform designed to help administrators interact with remote servers. It provides a browser-based interface for SSH terminal access, tunneling services, and file system management, allowing teams to perform administrative tasks directly from their web browsers instead of using traditional local terminal clients.

How does CVE-2026-45750 enable command injection?

This vulnerability, classified as CWE-78 (OS Command Injection), occurs because the software fails to properly sanitize user-supplied file paths. When these paths are sent to an active SSH session, the system mistakenly interprets specific characters as shell commands. This allows an attacker to manipulate the input so the server executes unintended, malicious commands instead of just resolving a file path.

Does this bug trigger automatically without user interaction?

No, this vulnerability does not trigger on its own. An attacker must have authenticated access to the platform and specifically interact with the vulnerable file path resolution function. Simply accessing the Termix web interface or browsing files normally will not trigger the bug; it requires the submission of specially crafted, malicious input designed to exploit the command substitution syntax.

Why is this Termix vulnerability a concern for my infrastructure?

According to Halo Surface Signal, Termix is frequently deployed as an internet-facing management gateway. Because it acts as a bridge between the public web and your internal server environment, any vulnerability here effectively lowers the barrier for attackers to reach your private systems. If an instance is reachable from the internet, it becomes a high-priority target for unauthorized remote code execution.

How do I secure my environment against this CVE?

The most effective way to address this is to upgrade to Termix version 2.3.2 or later, which contains the necessary security fixes for the path processing logic. Before applying the update, verify which instances are currently active in your environment, determine which are reachable from the internet, and coordinate with your platform team to schedule a maintenance window for the update.
