Patch Tuesday patches CVE-2022-22047 and more
The July 2022 Patch Tuesday brought fixes for 84 CVEs in various Microsoft products, including an actively exploited zero-day: CVE-2022-22047, addressing a flaw in Windows' Client/Server Runtime Subsystem (CSRSS).
Microsoft noted that an attacker who successfully exploited this flaw could gain system privileges, but must first gain access to the system by exploiting the flaw in the code.
Although the vulnerability does not confer the ability to construct wormable payloads (i.e. requires a pre-existing foothold in the system), Microsoft says it's being actively exploited in the wild, so patching should be a priority.
Finally, worth mentioning is this month Microsoft will start testing the new Windows Autopatch service for the business customers who have opted to use it.
