An OS command injection vulnerability exists in XWEB Pro version 1.12.1 and prior, specifically within the firmware update route. The vulnerability, identified as CVE-2026-25195, allows an authenticated attacker to achieve remote code execution on the underlying system. The affected products include the Copeland XWEB 300D PRO, XWEB 500D PRO, and XWEB 500B PRO running firmware versions up to and including 1.12.1 . The core issue stems from improper neutralization of special elements used in an OS command (CWE-78) when the application processes a firmware update file . An attacker with valid credentials can craft a malicious firmware file that, when uploaded via the update mechanism, injects arbitrary operating system commands. These commands are then executed with the privileges of the application, leading to full system compromise. The vulnerability has a CVSS v3 base score of 8.0, classified as High severity, with a vector string of CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H . This indicates the attack is network-based, requires high privileges and attack complexity, but has a changed scope and high impact on confidentiality, integrity, and availability. The vulnerability was published on February 26, 2026, and the vendor, Copeland, has provided a fix, urging users to update to the latest firmware version immediately .
dailycve form:
Platform: Copeland XWEB Pro
Version: <=1.12.1
Vulnerability : OS Command Injection
Severity: High (8.0)
date: Feb 27 2026
Prediction: March 2026
What Undercode Say:
Analytics:
EPSS Score: 0.22% (low risk, higher than 45% of CVEs) .
Attack Vector: Network.
Complexity: High.
Privileges Required: High.
User Interaction: None.
Scope: Changed.
CWE: 78 .
Product Lines: XWEB 300D PRO, 500D PRO, 500B PRO .
Disclosure Date: 2026-02-27 .
Patch Source: Copeland software update portal .
Update Method: SYSTEM — Updates | Network menu .
How Exploit:
No public PoC available at this time. Theoretical exploitation involves crafting a malicious firmware file. Commands would be injected into a parameter processed by the system during upload. Example of injected command within a file parameter: firmware_version=$(malicious_command)
Protection from this CVE:
1. Isolate affected systems immediately. iptables -A INPUT -s <untrusted_network> -j DROP 2. Update firmware via vendor portal (if internet access is available and trusted). Navigate to SYSTEM -> Updates | Network and apply the latest patch from Copeland . 3. If updating is not possible, restrict access to the web interface. Use firewall rules to allow only specific admin IPs. iptables -A INPUT -p tcp --dport 80 -s <trusted_admin_IP> -j ACCEPT iptables -A INPUT -p tcp --dport 443 -s <trusted_admin_IP> -j ACCEPT iptables -A INPUT -p tcp --dport 80 -j DROP iptables -A INPUT -p tcp --dport 443 -j DROP 4. Monitor logs for unusual file uploads or processes. tail -f /var/log/syslog | grep -i "firmware|upload|error"
Impact:
Remote Code Execution: An authenticated attacker can execute arbitrary system commands.
Full System Compromise: Attackers can gain complete control over the XWEB Pro device .
Operational Disruption: Potential to manipulate HVAC and energy management systems, leading to environmental hazards or equipment damage .
Lateral Movement: Compromised devices can serve as an entry point to attack the wider corporate or OT network .
