Sophos Firewall Authentication Bypass (CVE-2022-1040)

Appliance Details

Sophos XG Firewall brings a fresh new approach to the way you manage your firewall, respond to threats, and monitor what’s happening on your network.


Sophos Firewall could allow a remote attacker to execute arbitrary code on the system, caused by an authentication bypass vulnerability in the User Portal and Webadmin.


By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.

POST /userportal/Controller?mode=8700&operation=1&datagrid=179&json={"x":"test"}


By turning this into a traffic file and matching rule, we are able to detect attempts to perform remote code execution on an affected system.


Idappcom has created signature 8022689 for this vulnerability.
