Microsoft July Patch Tuesday Resolves 123 Vulnerabilities

Microsoft's Patch Tuesday has arrived with 123 security fixes across 13 products, including a major wormable bug in the Windows Server DNS component.

July Patch Tuesday Arrives With Over 120 Updates

July Patch Tuesday has 123 vulnerabilities remediated, including 18 Critical with the remaining 105 marked Important. After next month, Microsoft will have released more updates than all of 2019 combined.

If you tuned in to last month’s Patch Tuesday, you would have learned Microsoft resolved an astonishing 129 vulnerabilities breaking all known records for the number of fixes released in a single month.

Support for Windows 7 and Windows Server 2008 (including R2) officially ended after January 14, but there are 35 vulnerabilities remediated for customers who purchased an extension agreement. 6 are Critical and 29 are Important, including the Remote Desktop Client vulnerability below which is very important.

Robert Brown, Director of Services for Syxsense said, “The Hijacking vulnerability announced on Friday could not have come at a worse time being so close to the July Patch Tuesday. Today we learned that very version has an elevation of privilege vulnerability. With OneDrive being closely integrated into the Microsoft real-estate, can you afford not to protect your remote workforce?”

Important Patch Tuesday Vulnerabilities

1. CVE-2020-1350

With a CVSS score of 10.0, this DNS Server has the highest independently-scored threat this month. However, it does have a countermeasure that can be deployed by modifying a registry key on each server. This requires the DNS service to be restarted in order for the countermeasure to take effect.

This could be difficult with these servers being highly distributed. This is not currently Public Aware or Weaponised, but exploitation is extremely likely, making it our top vulnerability of the month.

 

2. CVE-2020-1463

Media streaming is usually disabled on Windows 10 devices, but with so many users working from home, it is now more likely to be used in the enterprise. This elevation of privilege could be exposed by streaming videos within Microsoft Stream or Yammer containing a specially crafted application. The method to expose this has been made Public, which means this could become Weaponized very soon.

 

3. CVE-2020-1374

This vulnerability impacts Remote Desktop Client, still used by many organizations to support staff both from within the network and at home. Although this vulnerability doesn’t have the highest CVSS score (7.5), the technology is regularly used and exploited, so we highly recommend prioritizing this update. The exploit requires a sophisticated sequence of events to take place, but it can be exploited via a simple network with ‘None’ privileges required.

 

4. CVE-2020-1465

A new version of OneDrive was recently released to resolve a hijacking vulnerability. Version 20.073.0409.0003 should have been installed without delay, however an additional vulnerability has been discovered causing an elevation of privilege.
