Synopsis

The remote host is affected by an authenticated remote code execution vulnerability.

Description

An issue was discovered in GPON ONT Home Gateway Router web administration interface. Remote Command Execution could be triggered by sending a HTTP POST request to 'GponForm/diag_Form' URI with malicious shell script added to dest_host parameter. Because the router saves ping and traceroute command execution results in /tmp and transmits them to the user when the user revisits /diag.html, it's possible to execute arbitrary commands and retrieve their output.
This allows an attacker to fully control the target device.

Solution

Consult your vendor for a patch or a workaround.
