Four-Faith Industrial Router adjust_sys_time OS Command Injection

The Four-Faith router models F3x24 and F3x36 are affected by an operating system (OS) command injection vulnerability. At least firmware version 2.0 allows authenticated and remote attackers to execute arbitrary OS commands over HTTP when modifying the system time via apply.cgi. Additionally, this firmware version has default credentials which, if not changed, would effectively change this vulnerability into an unauthenticated and remote OS command execution issue.

Four-Faith Wireless Mobile Router F3x24 v1.0 devices allow remote code execution via the Command Shell (aka Administration > Commands) screen.
