Description

According to its model number and software version, the remote host is a Xerox WorkCentre device that reportedly has an as-yet unspecified command injection vulnerability in its web server. A remote attacker may be able to leverage this issue to execute arbitrary code via carefully crafted inputs on an affected web page.
