Critical Command Injection Vulnerability in Copeland XWEB EVO

## Overview Copeland XWEB EVO versions prior to 5.6.2 contain a critical command injection vulnerability. This flaw allows unauthenticated remote attackers to execute arbitrary commands as root. The vulnerability is tied to the setuid-root CGI script xwconsole.cgi. ## Technical Details Attackers can exploit this vulnerability by supplying malicious input through the sh parameter. This input is passed unsanitized to the popen() function, enabling full system compromise. The product line reached its end of service date in March 2026, which means no further updates or patches will be provided for earlier versions. ## Impact The CVSS score for this vulnerability is 9.3, indicating a high severity risk. Successful exploitation can lead to complete system control by an attacker, posing significant risks to any organization still using affected versions of XWEB EVO. ## Mitigation Defenders should upgrade to version 5.6.2 or later of Copeland XWEB EVO immediately. Organizations still using unsupported versions should consider decommissioning the affected systems or implementing strict network controls to limit exposure.
