Description
The vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The weakness exists due to command injection via the dest_host parameter in a diag_action=ping request to a GponForm/diag_Form URI. A remote attacker can inject arbitrary commands and execute arbitrary code because the router saves ping results in /tmp and transmits them to the user when the user revisits /diag.html.
