Sophos fixed a security issue in September 2022 after warning about active exploitation in the wild. The issue impacted versions 19.0.1 and older.

By January 2023, more than 4,000 internet-exposed appliances were still vulnerable to attacks, even though the vendor automatically rolled out a hotfix to appliances set to accept security updates.

Many of these appliances were older devices running end-of-life firmware that had to apply mitigations or manually apply the hotfix, and hackers have taken advantage of this gap.

“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.

“We immediately developed a patch for certain EOL firmware versions, which was automatically applied to the 99% of affected organizations that have ‘accept hotfix’ turned on.”

“Attackers commonly hunt for EOL devices and firmware from any technology vendor, so we strongly recommend that organizations upgrade their EOL devices and firmware to the latest versions.”

If the auto-update option for hotfixes has been disabled, it is recommended to enable it and then check to confirm the hotfix has been applied.

Update to one of the following versions of Sophos Firewall to fix CVE-2022-3236:

v19.0 GA, MR1, and MR1-1
v18.5 GA, MR1, MR1-1, MR2, MR3, and MR4
v18.0 MR3, MR4, MR5, and MR6
v17.5 MR12, MR13, MR14, MR15, MR16, and MR17
v17.0 MR10
v19.0 GA, MR1, and MR1-1
v18.5 GA, MR1, MR1-1, MR2, MR3, and MR4
v17.0 MR10

If you have an older version of the Sophos Firewall, you should upgrade to one of the listed releases.
