Detection & IOCsextracted from sources · hover to see the quote
- →Attacker must be authenticated (low privilege) and exploits via a network call to trigger malicious code in the context of the server's account — monitor for anomalous authenticated network calls to Exchange Server endpoints ↗
- →No user interaction required and attack vector is network — exploitation can occur remotely without any victim interaction; prioritize network-level monitoring of Exchange Server ↗
- →Exploitation assessed as 'More Likely' for latest software release — treat unpatched Exchange Servers as high-priority targets and monitor for exploitation attempts ↗
- ·Vulnerability affects Microsoft Exchange Server; specific affected versions are addressed by KB5026261 and KB5025903 — ensure patch applicability is confirmed against deployed Exchange versions before assuming coverage ↗
- ·Exploit has not been publicly disclosed or observed in the wild at time of advisory, but is rated 'Exploitation More Likely' — detection posture should be proactive rather than reactive ↗

[CRITICAL] Microsoft Patch Tuesday, June 2023 Edition
Microsoft Corp. today released software updates to fix dozens of security vulnerabilities in its Windows operating systems and other software. This month’s relatively light patch load has another added bonus for system administrators everywhere: It appears to be the first Patch Tuesday since March 2022 that isn’t marred by the active exploitation of a zero-day vulnerability in Microsoft’s products.
June’s Patch Tuesday features updates to plug at least 70 security holes, and while none of these are reported by Microsoft as exploited in-the-wild yet, Redmond has flagged several in particular as “more likely to be exploited.”
Top of the list on that front is CVE-2023-29357, which is a “critical” bug in Microsoft SharePoint Server that can be exploited by an unauthenticated attacker on the

[CRITICAL] Microsoft discloses 5 critical vulnerabilities in June's Patch Tuesday, no zero-days
Microsoft released its monthly security update Tuesday, disclosing 69 vulnerabilities across its suite of products and software. Five of these vulnerabilities are considered to be critical, 45 of them are listed as being high severity, 17 of them are medium severity and two are of low severity.
For the first time in four months, none of the vulnerabilities Microsoft disclosed this Patch Tuesday have been exploited in the wild. June is also closer to an average month for Microsoft’s security update after only disclosing 40 vulnerabilities last month, which was nearly a three-year low.
Cisco Talos discovered two vulnerabilities in Microsoft Excel that the company patched Tuesday. These are important-severity remote code execution vulnerabilities that are triggered if the targeted user open
