CVE-2026-20910: CWE-78 in Copeland Copeland XWEB 300D PRO
An OS command injection vulnerability exists in XWEB Pro version 1.12.1 and prior, enabling an authenticated attacker to achieve remote code execution on the system by injecting malicious input into the devices field of the firmware update action to achieve remote code execution.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-20910) affects Copeland XWEB 300D PRO devices running version 1.12.1 or earlier. It allows an authenticated attacker to perform OS command injection by supplying crafted input in the devices field during the firmware update process. Successful exploitation results in remote code execution, compromising confidentiality, integrity, and availability of the system. The CVSS 3.1 base score is 8.0, reflecting network attack vector, high privileges required, no user interaction, and complete impact on confidentiality, integrity, and availability. No vendor patch or advisory is currently available, and the product is not a cloud service.
Potential Impact
An attacker with authenticated access can execute arbitrary OS commands remotely on the affected device, potentially leading to full system compromise. This impacts confidentiality, integrity, and availability of the device and its data. The vulnerability is rated high severity with a CVSS score of 8.0. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict authenticated access to the device and monitor for suspicious activity related to firmware update actions. Avoid exposing the management interface to untrusted networks.
