CVE-2026-25111 is an OS command injection vulnerability found in Copeland XWEB Pro versions up to 1.12.1 . The issue resides in the application’s “restore route,” where the software fails to properly neutralize special elements in user-supplied input before using it to construct an operating system command . An attacker who has first authenticated to the XWEB Pro system can exploit this by sending a specially crafted request to this specific route . The malicious input, containing shell metacharacters, is passed unsanitized into a command executed by the underlying operating system . This allows the attacker to execute arbitrary commands with the privileges of the web application, typically leading to full remote code execution (RCE) on the device . The vulnerability is classified as high severity with a CVSS score of 8.0, reflecting its potential for complete compromise of confidentiality, integrity, and availability, although it requires high privileges to exploit . The attack vector is over the network, and its scope is changed, meaning the vulnerable component impacts resources beyond its security scope . This flaw is part of a larger set of 23 vulnerabilities disclosed in the Copeland XWEB platform .
dailycve form:
Platform: Copeland XWEB Pro
Version: <=1.12.1
Vulnerability: OS command injection
Severity: High (CVSS 8.0)
date: 02/26/2026
Prediction: Patch already available
What Undercode Say:
Analytics:
The vulnerability is present in the following products:
- XWEB 300D PRO (versions 1.12.1 and prior)
- XWEB 500D PRO (versions 1.12.1 and prior)
- XWEB 500B PRO (versions 1.12.1 and prior)
The CVSS vector string is CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H . The vulnerability is categorized under CWE-78: Improper Neutralization of Special Elements used in an OS Command (‘OS Command Injection’) .
How Exploit:
An authenticated attacker can exploit this by injecting commands into parameters of the restore route. A conceptual example of an HTTP request that attempts to execute the `id` command:
Example of a malicious POST request to the restore route The parameter "restore_file" is injected with a command curl -X POST -u "username:password" \ "http://<target_ip>/restore" \ --data 'restore_file=backup.tar.gz; id;'
The application would then execute the command, returning the output of `id` to the attacker or allowing further payloads.
Protection from this CVE
- Patch Immediately: Update to the latest firmware version via the official Copeland software update portal .
- Network Isolation: Ensure XWEB Pro devices are not directly exposed to the public internet and are isolated behind a secure VPN .
- Input Validation: As a general practice, ensure all user inputs are strictly validated and sanitized against a whitelist.
Impact:
Successful exploitation allows an authenticated attacker to achieve remote code execution on the underlying system . This could lead to a full system compromise, including data theft, installation of persistent backdoors, and disruption of energy management or HVAC services . Because the CVSS scope is changed, the attacker may also be able to affect other resources beyond the vulnerable component .
