Sophos was forced to backport a security update for CVE-2022-3236 for end-of-life firewall firmware versions after discovering hackers actively exploiting the flaw in attacks.
Although the hotfix was automatically rolled out to appliances set to auto-accept security updates by the vendor, by January 2023, over 4,000 internet-exposed appliances remained vulnerable to attacks.
"In December 2023, we delivered an updated fix after identifying new exploit attempts against this same vulnerability in older, unsupported versions of the Sophos Firewall," reads the updated security bulletin.
