# Vulnerability: Microsoft August Patch Tuesday Summary (109 CVEs)
## CVE Details
- CVE ID: Multiple CVEs disclosed in the August Microsoft Patch Tuesday (Specific IDs not listed individually in the summary, except for two referenced actively discussed ones).
- CVSS Score: Ranges from 8.0 up to **10.0** (for one Azure-related issue).
- CWE: Not specified, but impacts include Elevation of Privilege (44), Remote Code Execution (35), Information Disclosure (18), etc.
## Affected Systems
- Products: Windows (65 addressed CVEs), Microsoft 365 (16), Office (16), Azure (7), SQL (6), Exchange (5), Excel (4), SharePoint (4), Word (3), Dynamics 365 (2), PowerPoint (1), Teams (1), Visual Studio (1), Web Deploy (1), Windows Security App (1), and WSL2 (1).
- Versions: Not specified individually; covers product families listed above that were due for patching in the August cycle.
- Configurations: Some Azure vulnerabilities were mitigated prior to the release.
## Vulnerability Description
Microsoft released 109 total patches impacting 16 product families. Eighteen flaws are rated Critical severity, and 31 have a base CVSS score of 8.0 or higher. The highest severity issue (CVSS 10.0) affects Azure. The majority of flaws result in Elevation of Privilege (44), followed by Remote Code Execution (35).
## Exploitation
- Status: **None known to be under active exploit in the wild** at the time of release, but two Windows issues (**CVE-2025-53786** and **CVE-2025-53779**) are already publicly disclosed. CISA has issued an Emergency Directive for CVE-2025-53786 (Hybrid Exchange Deployments).
- Complexity: Microsoft estimates nine CVEs are more likely to be exploited in the next 30 days.
- Attack Vector: Varies widely across the 109 CVEs, spanning RCE, EoP, and Info Disclosure vectors.
## Impact
- Confidentiality: Impacted by 18 vulnerabilities.
- Integrity: Impacted by 1 vulnerability (Tampering).
- Availability: Impacted by 4 vulnerabilities (Denial of Service).
(Note: RCE and EoP impacts often mean high impact across C-I-A scores, though specific breakdowns are not provided for every CVE boundary.)
## Remediation
### Patches
- All 109 documented vulnerabilities are addressed by the August Patch Tuesday roll-up.
- Eight CVEs (mostly Azure/365 related, including the CVSS 10.0 flaw) were already patched in the July cycle but were included in the August documentation due to a clerical error.
### Workarounds
- No specific workarounds are listed in this summary, as the focus is on applying the comprehensive August patches. (Note: CISA issued specific guidance for CVE-2025-53786, which acts as an urgent pre-patch directive.)
## Detection
- Detection: Sophos protections can directly detect various aspects of these issues.
- Indicators of Compromise: Sophos includes specific detection guidance in an accompanying table (not visible in this summary text). Specific IoCs for the publicly disclosed CVE-2025-53786 are relevant due to the CISA Directive.
