Security News > 2023 > January > Over 4,000 Sophos Firewall devices vulnerable to RCE attacks
Over 4,000 Sophos Firewall devices exposed to Internet access are vulnerable to attacks targeting a critical remote code execution vulnerability.
Sophos disclosed this code injection flaw found in the User Portal and Webadmin of Sophos Firewall in September and also released hotfixes for multiple Sophos Firewall versions.
Sophos Firewall instances running older product versions had to be upgraded manually to a supported version to receive the CVE-2022-3236 hotfix automatically.
While scanning the Internet for Sophos Firewall devices, VulnCheck vulnerability researcher Jacob Baines found that out of more than 88,000 instances, around 6% or more than 4,000 are running versions that haven't received a hotfix and are vulnerable to CVE-2022-3236 attacks.
Sophos Firewall bugs previously targeted in attacks.
In March 2022, Sophos patched a similar critical Sophos Firewall bug in the User Portal and Webadmin modules that enabled authentication bypass and arbitrary code execution attacks.
