AI-suggested

European organizations should immediately verify their Sophos Firewall versions and upgrade to version 21.0 MR2 (21.0.2) or later where this vulnerability is addressed. If immediate patching is not feasible, organizations should restrict network access to the WebAdmin interface and HA auxiliary devices to trusted management networks only, using network segmentation and firewall rules to limit exposure. Disabling OTP authentication temporarily on admin accounts, if feasible, may reduce the attack surface, but this should be balanced against the security benefits of OTP. Monitoring firewall logs for unusual activity and implementing intrusion detection systems to detect command injection attempts can provide early warning. Organizations should also review and harden administrative access policies, including strong password enforcement and multi-factor authentication methods beyond OTP if possible. Regular backups of firewall configurations and system states should be maintained to enable rapid recovery in case of compromise. Finally, organizations should engage with Sophos support channels to obtain official patches and guidance, and stay alert for any emerging exploit reports or indicators of compromise related to this vulnerability.

Description

A command injection vulnerability in WebAdmin of Sophos Firewall versions older than 21.0 MR2 (21.0.2) can lead to adjacent attackers achieving pre-auth code execution on High Availability (HA) auxiliary devices, if OTP authentication for the admin user is enabled.
