An OS command injection vulnerability exists in Copeland XWEB Pro version 1.12.1 and prior. The flaw resides in the “devices” field of the firmware update apply action. When the system processes a firmware update request, it fails to properly neutralize special elements in user-supplied input. An authenticated attacker can inject arbitrary operating system commands into this specific field. Because the application does not sanitize the input, the injected commands are concatenated into a command string that is executed by the underlying operating system with the privileges of the web service. This allows the attacker to achieve remote code execution (RCE) on the affected device, potentially leading to full system compromise. The vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command.
Platform: Copeland XWEB Pro
Version: ≤ 1.12.1
Vulnerability : OS Command Injection
Severity: HIGH (CVSS 8.0)
date: 2026-02-26
Prediction: Patch released 2026-02-27

Analytics
The CVE was published on February 26, 2026, by ICS-CERT. It has a CVSS base score of 8.0 (HIGH) with a vector string of CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H. The attack complexity is high, and it requires high privileges, but it has a changed scope, meaning the vulnerable component impacts resources beyond its security scope. The vulnerability was discovered and reported by Amir Zaltzman and Noam Moshe of Claroty Team82. It is one of 23 vulnerabilities disclosed in the Copeland XWEB Pro suite.
Bash Commands and Code
While a specific public PoC for CVE-2026-24689 is not available in the search results, the exploitation concept involves injecting commands via the `devices` parameter during a firmware update. A conceptual cURL command might look like this:
Conceptual Example - Do not use without authorization This injects a sleep command via the devices field curl -X POST -u "username:password" \ "http://<target_ip>/firmware_update_apply_action" \ --data "devices=1; sleep 20;&filename=update.bin"
Alternatively, an attacker might use command chaining:
Conceptual Example - Attempt to create a file curl -X POST -u "username:password" \ "http://<target_ip>/firmware_update_apply_action" \ --data "devices=1; touch /tmp/exploit.txt;&filename=update.bin"
How Exploit
- Authentication: The attacker must first authenticate to the XWEB Pro web interface with valid credentials.
- Vector: The attacker navigates to the firmware update functionality and intercepts the request to the “apply action” endpoint.
- Injection: The attacker modifies the `devices` field in the request. Instead of a valid device ID, they input a malicious payload, such as
1; whoami > /tmp/output.txt;. - Execution: The server-side code takes this input and incorporates it into a system command (e.g.,
firmware-tool --devices [bash] --apply). Due to the semicolon, the operating system executes the injected `whoami` command after the intended command. - Result: The attacker achieves remote code execution, allowing them to read, modify, or disrupt the system.
Protection from this CVE
Patch Immediately: Update to the latest firmware version available on the official Copeland software update page (`https://webapps.copeland.com/Dixell/Pages/SystemSoftwareUpdate`). For internet-connected devices, use the menu: SYSTEM → Updates | Network.
Network Segmentation: Ensure XWEB Pro devices are not directly exposed to the public internet. Isolate them behind firewalls and secure VPNs.
Input Validation: As a vendor mitigation, implement strict allow-listing for all input fields, particularly those interacting with the OS.
Access Control: Enforce the principle of least privilege for user accounts. Limit the number of users with administrative access to the firmware update functionality.
Impact
Successful exploitation allows an authenticated attacker to execute arbitrary code on the system. This could lead to:
Full System Compromise: The attacker gains control over the XWEB Pro energy management platform.
Operational Disruption: Attackers could modify configurations, shut down systems, or corrupt data, impacting commercial facilities where these systems are deployed.
Lateral Movement: The compromised device could be used as a foothold to attack other systems within the same network.
Data Breach: Confidentiality is impacted as attackers can access sensitive data processed by the XWEB system.
