info:
|
|
name: Dasan GPON Devices - Remote Code Execution
|
|
author: gy741
|
|
severity: critical
|
|
description: Dasan GPON home routers are susceptible to command injection which can occur via the dest_host parameter in a diag_action=ping request to a GponForm/diag_Form URI. Because the router saves ping results in /tmp and transmits them to the user when the user revisits /diag.html, it's quite simple to execute commands and retrieve their output.
|
|
impact: |
|
|
Successful exploitation of this vulnerability allows an attacker to execute arbitrary commands with root privileges on the affected device.
|
|
remediation: |
|
|
Apply the latest firmware update provided by the vendor to mitigate this vulnerability.
