Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by sending specially crafted commands through the device's web configuration interface. This could occur without any authentication, allowing them to execute arbitrary operating system commands on the affected system.

No authentication required for attack.
Triggered via web configuration commands.
Leads to remote command execution.

Live Threat

Current exploitation, exposure, and threat context

A remote command execution vulnerability in SE-elektronic GmbH's E-DDC3.3 devices could allow an unauthenticated attacker to send arbitrary operating system commands to the system via its web configuration interface. This could affect the device's integrity and availability when accessed over a network.

System commands can be executed.
Via unauthenticated web interface access.
Potential compromise of device functions.

Operational Fix

Recommended remediation, mitigation, and detection steps

This remote command execution vulnerability in SE-elektronic E-DDC3.3 devices impacts their web configuration functionality, making them a potential target for attackers. Infrastructure and network teams are likely responsible for managing these devices. The first practical step is to identify all E-DDC3.3 devices within the environment, confirm their exposure and criticality, and then engage the appropriate system owner to plan remediation.

Infrastructure and network teams own remediation.
Verify device exposure and criticality first.
Plan and coordinate system updates or controls.

Frequently asked questions

What is the SE-elektronic E-DDC3.3?

The E-DDC3.3 is a specialized piece of hardware from SE-elektronic GmbH, typically used for industrial or building control automation. It acts as a controller for various mechanical or electrical systems. These devices often include a web-based configuration interface, which administrators use to manage settings and monitor operations directly over a network.

What does CWE-94 mean for CVE-2024-1015?

CVE-2024-1015 involves a weakness known as CWE-94, or Improper Control of Generation of Code. In plain terms, this means the software incorrectly handles input in a way that allows an attacker to inject and execute their own operating system commands. By sending specific, malicious commands to the device's web configuration portal, an attacker can trick the system into running unauthorized code with the device's full system permissions.

How is this vulnerability triggered?

The vulnerability is triggered by sending specially crafted commands to the device's web configuration interface. Importantly, this does not require any pre-existing credentials or login sessions. If the attacker can reach the web interface, they can initiate the command execution. Simply visiting the login page or monitoring the device without sending these specific malicious commands would not trigger the vulnerability.

Who should care about CVE-2024-1015?

Organizations using SE-elektronic E-DDC3.3 devices should prioritize this. Halo Surface Signal notes that because this vulnerability exists within a web-based management interface, these devices are often deployed in ways that make them reachable over a network. If your E-DDC3.3 interface is exposed to the internet or accessible from an untrusted network segment, the risk of unauthorized remote interaction increases significantly.

How do I respond to this vulnerability?

Your first step is to locate all E-DDC3.3 controllers within your environment to understand your footprint. Once identified, verify if those specific devices are accessible over your network and assess how critical they are to your operations. Coordinate with your infrastructure or network teams to confirm the device versions and then plan for necessary updates or implement network-level controls to restrict access to the web interface while you finalize a long-term solution.
