Microsoft Fixes Two Zero-Days This Patch Tuesday

Microsoft released fixes for in excess of 60 CVEs this thirty day period like two zero-working day vulnerabilities, one particular of which is remaining actively exploited in the wild.

The latter is an elevation of privilege vulnerability in Windows Popular Log File System Driver (CVE-2022-37969), which impacts all Windows variations and could permit attackers to achieve method privileges.

“The attack does have to have the attacker to have obtain and potential to run code on the goal process, but chaining numerous vulnerabilities in an attack is typical sufficient apply that this should be regarded a minor barrier for risk actors,” described Ivanti VP of security items, Chris Goettl.

“The vulnerability is rated as ‘important,’ but with a number of vendors acknowledged for the coordinated disclosure and verified exploits in the wild it should really be dealt with as a ‘critical’ severity due to the risk. Exploitation has previously been detected and added information could have been disclosed earning it less difficult for extra attackers to get benefit of the vulnerability.”

The next publicly disclosed bug is located in in ARM-primarily based Windows 11 units and could permit cache speculation restriction (CVE-2022-23960). Recognized as Spectre-BHB, it could be described as a side-channel speculation vulnerability in ARM processors.

This month’s Patch Tuesday update spherical has viewed Microsoft pass 1000 CVEs for the 12 months, placing the company on monitor to exceed the 1200 it fastened in 2021, in accordance to Qualys.

There are a total of five critical patches for sysadmins to take into account this month, together with distant code execution bugs CVE-2022-34722 and CVE-2022-34721, which affect Windows Internet Crucial Exchange (IKE) Protocol Extensions. Both have a CVSS score of 9.8.

“They equally have lower complexity for exploitation and permit danger actors to execute the attack with no user interaction. An unauthenticated attacker could send a specifically crafted IP packet to a goal machine that is running Windows and has IPSec enabled, which could allow remote code execution,” warned Motion1 co-founder, Mike Walters.

“This vulnerability impacts only IKEv1 and not IKEv2. Even so, all Windows Servers are impacted because they take each V1 and V2 packets. There is no exploit or proof-of-principle detected in the wild still, but putting in the resolve is highly sensible.”
