Cybersecurity firm Sophos on Monday warned that a recently patched critical security vulnerability in its firewall product is being actively exploited in real-world attacks.
The flaw, tracked as CVE-2022-1040, is rated 9.8 out of 10 on the CVSS scoring system and impacts Sophos Firewall versions 18.5 MR3 and older.
It relates to an authentication bypass vulnerability in the User Portal and Webadmin interface that, if successfully weaponized, allows a remote attacker to execute arbitrary code.
"Sophos has observed this vulnerability being used to target a small set of specific organizations primarily in the South Asia region," the company noted in a revised advisory published Monday.
"We have informed each of these organizations directly."
As a workaround, Sophos is recommending that users disable WAN access to the User Portal and Webadmin interfaces.
