Privilege Escalation Vulnerability

The EPSON Network utility included with some older Epson printers installs a binary with weak permissions, which can allow a low privilege user to escalate their privileges and take control of the system.
 
Successful exploitation of this vulnerability can lead to unauthorized control of the system by a low privilege user.
