Detection & IOCsextracted from sources · hover to see the quote
- →The vulnerability is triggered via a crafted malicious link that bypasses the Protected View Protocol in Microsoft Outlook, leading to RCE — monitor for Outlook processes spawning unexpected child processes after link interaction. ↗
- →Exploitation requires user interaction — specifically a user allowing blocked content from an external sender. Alert on Outlook 'Allow' actions on externally-originated blocked content. ↗
- →The Preview Pane is NOT an attack vector; focus detection on full message open and link-click events rather than previewPane rendering. ↗
- →Successful exploitation grants high-privilege read/write/delete capability — post-exploitation activity may include file creation/deletion or credential access; monitor for anomalous OUTLOOK.EXE file I/O and privilege escalation indicators. ↗
- →Affected products include Microsoft Office 2016 (32/64-bit), Office LTSC 2021, Microsoft 365 Apps for Enterprise, and Office 2019 — scope detection rules to these Office versions. ↗
- ·Exploitation is rated 'Exploitation More Likely' by Microsoft but has not been publicly exploited or disclosed as of the advisory date — prioritize patching over detection tuning. ↗
- ·The attack vector is Network and requires user interaction (UI:R); zero-click exploitation is not possible — detection should focus on user-initiated link-click events in Outlook. ↗

[HIGH] Largest Patch Tuesday in 3 months includes 5 critical vulnerabilities
## Largest Patch Tuesday in 3 months includes 5 critical vulnerabilities
Microsoft released its monthly security update on Tuesday, disclosing 142 vulnerabilities across its suite of products and software. Of those, there are five critical vulnerabilities, and every other security issue disclosed this month is considered "important."
This is the largest Patch Tuesday since April when Microsoft patched 150 vulnerabilities.
Of the critical vulnerabilities, two are considered more likely to be exploited:
CVE-2024-38023 , a remote code execution vulnerability in Microsoft SharePoint server, where an authenticated attacker with Site Owner permissions can use the vulnerability to execute arbitrary code in the context of SharePoint server.

CVE-2024-38080 [CRITICAL] Microsoft Patch Tuesday, July 2024 Edition
Microsoft Corp. today issued software updates to plug at least 139 security holes in various flavors of Windows and other Microsoft products. Redmond says attackers are already exploiting at least two of the vulnerabilities in active attacks against Windows users.
The first Microsoft zero-day this month is CVE-2024-38080 , a bug in the Windows Hyper-V component that affects Windows 11 and Windows Server 2022 systems. CVE-2024-38080 allows an attacker to increase their account privileges on a Windows machine. Although Microsoft says this flaw is being exploited, it has offered scant details about its exploitation.
The other zero-day is CVE-2024-38112 , which is a weakness in MSHTML , the proprietary engine of Microsoft’s Internet Explorer web browser. Kevin Breen , senior director of thre
