Security software company Sophos has warned of cyberattacks targeting a recently addressed critical vulnerability in its firewall product.
The issue, tracked as CVE-2022-3236 (CVSS score: 9.8), impacts Sophos Firewall v19.0 MR1 (19.0.1) and older and concerns a code injection vulnerability in the User Portal and Webadmin components that could result in remote code execution.
The company said it “has observed this vulnerability being used to target a small set of specific organizations, primarily in the South Asia region,” adding it directly notified these entities.
As a workaround, Sophos is recommending that users take steps to ensure that the User Portal and Webadmin are not exposed to WAN. Alternatively, users can update to the latest supported version -
- v19.5 GA
- v19.0 MR2 (19.0.2)
- v19.0 GA, MR1, and MR1-1
- v18.5 MR5 (18.5.5)
- 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
Users running older versions of Sophos Firewall are required to upgrade to receive the latest protections and the relevant fixes.
The development marks the second time a Sophos Firewall vulnerability has come under active attacks within a year. Earlier this March, another flaw (CVE-2022-1040) was used to target organizations in the South Asia region.
Then in June 2022, cybersecurity firm Volexity shared more details of the attack campaign, pinning the intrusions on a Chinese advanced persistent threat (APT) known as DriftingCloud.
Sophos firewall appliances have also previously come under attack to deploy what’s called the Asnarök trojan in an attempt to siphon sensitive information.

Executive summary Since the Russian invasion of Ukraine began, Ukrainians have been under a nearly constant barrage of cyber attacks. Working jointly with Ukrainian organizations, Cisco Talos has discovered a fairly uncommon piece of malware targeting Ukraine — this time aimed at a large software development company whose software is used in various state organizations within Ukraine. We believe that this campaign is likely sourced by Russian state-sponsored actors or those acting in their interests. As this firm is involved in software development, we cannot ignore the possibility that the perpetrating threat actor's intent was to gain access to source a supply chain-style attack, though at this time we do not have any evidence that they were successful. Cisco Talos confirmed that the malware is a slightly modified version of the open-source backdoor named "GoMet." The malware was first observed on March 28, 2022.
