CVE-2018-8581 is a privilege escalation vulnerability in Microsoft Exchange Server that, when successfully exploited, allows an attacker to impersonate any other user of the Exchange server. Impersonating an arbitrary user lets the attacker act as that user — reading their mailbox, sending messages as them, and, if the impersonated account is privileged or administrative, gaining elevated access to the messaging environment. Organizations running on-premises Microsoft Exchange Server are affected; the provided data does not specify the affected version ranges, so operators should consult Microsoft's CVE-2018-8581 advisory for the exact builds covered. CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2022-03-03 with known ransomware use, confirming in-the-wild exploitation, and EPSS assigns a 27.4% probability of exploitation in the next 30 days (98th percentile). No public proof-of-concept is known, but the KEV listing and ransomware linkage make patching exposed Exchange servers urgent.

Do: Apply Microsoft's Exchange security updates per vendor instructions, as required by the CISA KEV listing, and confirm the patched build for your Exchange version in Microsoft's CVE-2018-8581 advisory since affected version ranges are not enumerated in this data. Because ransomware operators are known to exploit this flaw, prioritize internet-facing Exchange servers and hunt for signs of compromise — unexpected user impersonation, anomalous mailbox access, and post-exploitation activity — before and after patching.

CVE-2018-8589 is an elevation of privilege vulnerability in Win32k.sys, the Windows kernel-mode component that handles system calls, affecting Windows 7, Windows Server 2008, and Windows Server 2008 R2. It is triggered when Windows improperly handles calls to Win32k.sys, allowing a local attacker who is already able to execute low-privileged code (for example, via a malicious application or as a second stage of a browser exploit) to escalate privileges. A successful exploit grants the attacker elevated (kernel/SYSTEM-level) privileges on the local machine, typically enabling full control and often chained with code-execution bugs. Windows 7 and Windows Server 2008/2008 R2 users and administrators are affected; the flaw was patched in Microsoft's November 2018 security updates. The vulnerability was known to be actively exploited in the wild at the time of the November 2018 Patch Tuesday, and it is listed in CISA's Known Exploited Vulnerabilities catalog (added May 23, 2022), with EPSS at roughly 3% (87th percentile).

Do: Apply the Microsoft November 2018 security updates (or later) to all Windows 7, Windows Server 2008, and Windows Server 2008 R2 systems, per the CISA KEV required action. Because Windows 7 and Server 2008 are past end of support, verify patch status on legacy/extended-support (ESU) systems, inventory any remaining unpatched hosts, and prioritize upgrading them; until patched, limit execution of untrusted local code and keep kernel exploit mitigations enabled.

A Cross-site Scripting (XSS) vulnerability exists when Azure App Services on Azure Stack does not properly sanitize user provided input, aka "Azure App Service Cross-site Scripting Vulnerability." This affects Azure App.

A Cross-site Scripting (XSS) vulnerability exists when Team Foundation Server does not properly sanitize user provided input, aka "Team Foundation Server Cross-site Scripting Vulnerability." This affects Team.

A remote code execution vulnerability exists in Microsoft Dynamics 365 (on-premises) version 8 when the server fails to properly sanitize web requests to an affected Dynamics server, aka "Microsoft Dynamics 365 (on-premises) version 8 Remote Code Execution Vulnerability." This affects Microsoft Dynamics 365.
