Windows IIS Server Elevation of Privilege Vulnerability
FAQ: How could an attacker exploit this vulnerability?
In a network-based attack, an attacker could brute force user account passwords to log in as that user. Microsoft encourages the use of strong passwords that are more difficult for an attacker to brute force.
FAQ: Why is the severity for this CVE rated as Important, but the CVSS score is 9.8?
The Microsoft proprietary severity rating does not align with the CVSS scoring system. In this case, the severity rating of Important (rather than Critical) reflects the fact that brute-force attacks are unlikely to succeed against users with strong passwords. The CVSS scoring system doesn't allow for this type of nuance.

Twenty years ago this month, Microsoft introduced the concept of “Patch Tuesday” – although the marketing folks wanted it called “Update Tuesday” (they didn’t like the word “patch”). Over the years, more companies joined the Patch Tuesday bandwagon. Here we are 20 years later, still talking about the latest security releases from Adobe and Microsoft. Pop some champagne to celebrate and join us as we review the details of the latest advisories from Adobe and Microsoft. If you’d rather watch the video recap, you can check it out here.

Microsoft Exchange gets ‘better’ patch to mitigate critical bug

CVE-2023-21709 [CRITICAL] Microsoft Exchange gets ‘better’ patch to mitigate critical bug
## Microsoft Exchange gets ‘better’ patch to mitigate critical bug
## Sergiu Gatlan
Even though Microsoft released security updates to fix the vulnerability, it also informed Exchange admins that they'd also have to remove the vulnerable Windows IIS Token Cache module manually or use this PowerShell script to ensure their servers are protected against attacks using CVE-2023-21709 exploits.
As part of this month's Patch Tuesday, Microsoft has now released a new security update (CVE-2023-36434) that fully addresses the CVE-2023-21709 flaw and doesn't require any additional steps.
"During the release of August 2023 SUs, we recommended to use a manual or scripted solution and disable the IIS Token Cache module as a way of addressing CVE-2023-21709," the Exchange Team said .
