BEC Technologies Multiple Routers sys ping Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of BEC Technologies Multiple Routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the management interface, which listens on TCP port 22 by default.
