FULL STORY ======================================================================Sophos says it found, and patched, three flaws in its firewall product The flaws allowed for RCE and privilege escalation Those unable to apply the patch can use a workaround

Sophos has recently discovered, and patched, three bugs in its Firewall product, and given the severity, has urged users to apply the fixes as soon
as possible. Those that cannot do that are advised to at least apply the suggested mitigation workarounds.

A security advisory from the company notes the three vulnerabilities can be abused for remote code execution, privileged system access, and more. Two of the flaws were given a critical severity score (9.8), with the third one
being high-severity (8.8).

Multiple versions of the Sophos Firewall were said to be affected, although different versions seem to be susceptible to different flaws. Still, the company urges all users to bring their endpoints to the latest version and avoid getting targeted. Workaround possible

Patching also differs, depending on the vulnerability in question. For CVE-2024-12727 users should launch Device Management, navigate to Advanced Shell from the Sophos Firewall console, and run the command "cat /conf/nest_hotfix_status".

For the remaining two flaws, users should launch Device Console from the Sophos Firewall console, and run the command "system diagnostic show version-info".

Users that cannot apply the patch should at least apply the suggested workaround, which includes restricting SSH access to only the dedicated HA link that is physically separate. Furthermore, users should reconfigure HA using a sufficiently long and random custom passphrase.

Finally, they can disable WAN access via SSH, and make sure that the User Portal and Webadmin are not exposed to WAN.

Firewalls are major targets in cyberattacks because they act as the primary gatekeepers between internal networks and external threats, making them critical points of defense for sensitive data and systems.

Compromising a firewall can grant attackers privileged access to a network, bypassing security controls and exposing the entire system to further exploitation. Additionally, firewalls often hold valuable configuration data and access credentials, which attackers can leverage to escalate their
attacks or maintain persistent access.
