Description

A SQL injection issue was found in SFOS 17.0, 17.1, 17.5, and 18.0 before 2020-04-25 on Sophos XG Firewall devices. This vulnerability was exploited in the wild as of April 2020. The attack affected systems configured with either the administration interface (HTTPS admin service) or the user portal exposed on the WAN zone. In addition, firewalls manually configured to expose a firewall service (e.g. SSL VPN, SPX Portal) to the WAN zone that shares the same port as the admin or user portal were also affected. A successful attack may have caused remote code execution that exfiltrated usernames and hashed passwords for the local device admin(s), portal admins, and user accounts used for remote access (but not external Active Directory or LDAP passwords).
