Microsoft Issues Patches for 121 Flaws, Including Zero-Day Under Active Attack

Aug 10, 2022
As many as  121 new security flaws  were patched by Microsoft as part of its Patch Tuesday updates for the month of August, which also includes a fix for a Support Diagnostic Tool vulnerability that the company said is being actively exploited in the wild. Of the 121 bugs, 17 are rated Critical, 102 are rated Important, one is rated Moderate, and one is rated Low in severity. Two of the issues have been listed as publicly known at the time of the release. It's worth noting that the 121 security flaws are in addition to  25 shortcomings  the tech giant addressed in its Chromium-based Edge browser late last month and the previous week. Topping the list of patches is  CVE-2022-34713  (CVSS score: 7.8), a case of remote code execution affecting the Microsoft Windows Support Diagnostic Tool (MSDT), making it the second flaw in the same component after  Follina  (CVE-2022-30190) to be weaponized in  real-world attacks  within three months....
Patch Tuesday: Microsoft Issues Fix for Actively Exploited 'Follina' Vulnerability

Patch Tuesday: Microsoft Issues Fix for Actively Exploited 'Follina' Vulnerability

Jun 15, 2022
Microsoft finally released fixes to address an actively exploited Windows zero-day vulnerability known as Follina as part of its Patch Tuesday updates. Also addressed by the tech giant are  55 other flaws , three of which are rated Critical, 51 are rated Important, and one is rated Moderate in severity. Separately, five more shortcomings were resolved in the Microsoft Edge browser. Tracked as  CVE-2022-30190  (CVSS score: 7.8), the  zero-day bug  relates to a remote code execution vulnerability affecting the Windows Support Diagnostic Tool (MSDT) when it's invoked using the "ms-msdt:" URI protocol scheme from an application such as Word. The vulnerability can be trivially exploited by means of a specially crafted Word document that downloads and loads a malicious HTML file through Word's remote template feature. The HTML file ultimately permits the attacker to load and execute PowerShell code within Windows. "An attacker who successfully exploits thi...

Microsoft's New Autopatch Feature to Help Businesses Keep Their Systems Up-to-Date

Microsoft's New Autopatch Feature to Help Businesses Keep Their Systems Up-to-Date

Apr 11, 2022
Microsoft last week announced that it intends to make generally available a feature called Autopatch as part of Windows Enterprise E3 in July 2022. "This service will keep Windows and Office software on enrolled endpoints up-to-date automatically, at no additional cost,"  said  Lior Bela, senior product marketing manager at Microsoft, in a post last week. "The second Tuesday of every month will be 'just another Tuesday.'" Windows Autopatch is intended to work with all supported versions of Windows 10, Windows 11, and Windows 365 for Enterprise. Windows Server OS and Windows 365 for Business, however, are not supported. The tech giant said the feature is aimed at tackling the complexity associated with software updates in enterprise IT environments as well as closing security gaps introduced as a result of not applying patches in a timely fashion, thereby opening the door to potential new threats.  The managed service works by applying the updates acro...

Microsoft's Emergency Patch Fails to Fully Fix PrintNightmare RCE Vulnerability

Microsoft's Emergency Patch Fails to Fully Fix PrintNightmare RCE Vulnerability

Jul 08, 2021
Even as Microsoft  expanded patches  for the so-called PrintNightmare vulnerability for Windows 10 version 1607, Windows Server 2012, and Windows Server 2016, it has come to light that the fix for the remote code execution exploit in the Windows Print Spooler service can be bypassed in certain scenarios, effectively defeating the security protections and permitting attackers to run arbitrary code on infected systems. On Tuesday, the Windows maker issued an  emergency out-of-band update  to address  CVE-2021-34527  (CVSS score: 8.8) after the flaw was accidentally disclosed by researchers from Hong Kong-based cybersecurity firm Sangfor late last month, at which point it emerged that the issue was different from another bug — tracked as  CVE-2021-1675  — that was patched by Microsoft on June 8. "Several days ago, two security vulnerabilities were found in Microsoft Windows' existing printing mechanism," Yaniv Balmas, head of cyber research at C...
Microsoft Issues Emergency Patch for Critical Windows PrintNightmare Vulnerability

Microsoft Issues Emergency Patch for Critical Windows PrintNightmare Vulnerability

Jul 07, 2021
Microsoft has shipped an  emergency out-of-band security update  to address a critical zero-day vulnerability — known as "PrintNightmare" — that affects the Windows Print Spooler service and can permit remote threat actors to run arbitrary code and take over vulnerable systems. Tracked as  CVE-2021-34527  (CVSS score: 8.8), the remote code execution flaw impacts all supported editions of Windows. Last week, the company warned it had detected active exploitation attempts targeting the vulnerability. "The Microsoft Windows Print Spooler service fails to restrict access to functionality that allows users to add printers and related drivers, which can allow a remote authenticated attacker to execute arbitrary code with SYSTEM privileges on a vulnerable system," the CERT Coordination Center said of the issue. It's worth noting that PrintNightmare includes both remote code execution and a local privilege escalation vector that can be abused in attacks to run com...
