🔧 Microsoft has issued a fix for an August 2025 update that caused unexpected User Account Control (UAC) prompts and blocked MSI app installations for non-administrative users across multiple Windows client and server releases. The behavior resulted from a security patch addressing CVE-2025-50173, which introduced broader elevation checks to mitigate privilege escalation. Microsoft’s September 2025 update narrows when UAC is required for MSI repairs and lets IT administrators add specific MSI packages to an allowlist via new SecureRepairPolicy and SecureRepairWhitelist registry keys. The company also resolved a separate bug that caused severe lag and stuttering in NDI streaming software on Windows 10 and Windows 11.

🔒 Adobe has issued an emergency patch for a critical input-validation vulnerability dubbed SessionReaper in Adobe Commerce and Magento. The flaw, tracked as CVE-2025-542360 with a CVSS score of 9.1, affects multiple 2.4.x releases and earlier. Sansec researchers said the bug can enable session hijacking and, according to the original finder, may allow unauthenticated remote code execution in some circumstances. Administrators are advised to deploy APSB25-88 immediately or enable a WAF as a temporary mitigation.

🔒 Microsoft released fixes for 80 security flaws across its products, including one publicly disclosed SMB privilege-escalation issue (CVE-2025-55234). Eight flaws are rated Critical and 72 Important, with a high proportion of elevation-of-privilege bugs. The update also includes a CVSS 10.0 Azure Networking fix and new auditing options to help administrators assess Windows SMB signing and Extended Protection compatibility before hardening.

⚠️ Microsoft released its monthly Patch Tuesday addressing 81 vulnerabilities, including two disclosed zero-days affecting SQL Server and SMB. The first, CVE-2024-21907, involves improper handling in Newtonsoft.Json used by SQL Server and can cause denial of service via deeply nested JSON. The second, CVE-2025-55234, is a remotely exploitable SMB elevation-of-privilege that can be mitigated by hardening features like SMB Server Signing and Extended Protection for Authentication; Microsoft also offers audit tools to check compatibility before enabling them.

⚠️ Adobe has disclosed a critical flaw, CVE-2025-54236 (SessionReaper), in Adobe Commerce and Magento Open Source that can enable attackers to take over customer accounts through the Commerce REST API. The issue, rated 9.1 by CVSS, stems from improper input validation and affects multiple product versions and a third-party module. Adobe published a hotfix and deployed WAF rules for cloud-hosted merchants while e-commerce security firm Sansec reproduced an exploitation path involving session manipulation and nested deserialization. Merchants should apply fixes, review session storage settings, and monitor for suspicious activity.

🔒 SAP on Tuesday released security updates addressing multiple vulnerabilities, including three critical flaws in SAP NetWeaver that could enable remote code execution and arbitrary file uploads (notably CVE-2025-42944, CVE-2025-42922 and CVE-2025-42958). The company also fixed a high-severity input-validation issue in SAP S/4HANA (CVE-2025-42916). Security researchers recommend immediate patching and temporary mitigations such as P4 port filtering to limit exposure.

🔔 CISOs with SAP NetWeaver AS Java deployments should urgently patch two critical flaws: CVE-2025-42944, a CVSS 10.0 insecure deserialization in the RMI-P4 module, and a CVSS 9.9 insecure file-upload vulnerability that can lead to full system compromise. As an immediate mitigation, admins can apply P4 port filtering at the ICM level until patches are installed. Microsoft released fixes for 13 critical bugs this month, including Hyper‑V guest-to-host escalation issues and an NTLM elevation flaw (CVE-2025-54918) marked Exploitation More Likely; teams should prioritize domain controllers and virtualization hosts.
