About Elevation of Privilege - Windows Update Service (CVE-2025-48799) vulnerability

About Elevation of Privilege – Windows Update Service (CVE-2025-48799) vulnerability. This vulnerability is from the July Microsoft Patch Tuesday. Improper link resolution before file access (‘link following’) in the Windows Update Service allows an authorized attacker to elevate privileges to “NT AUTHORITY\SYSTEM”.

🛠 An exploit for this vulnerability was published by researcher Filip Dragović (Wh04m1001) on July 8, the day of MSPT. In the exploit description, he states that the vulnerability affects Windows 10/11 systems with at least two hard drives. If the installation location for new apps is changed to the secondary drive (using Storage Sense), then during the installation of a new app, the wuauserv service will arbitrarily delete folders without checking for symbolic links, leading to to LPE.

🎞 In the demonstration video, Filip Dragović runs the EXE file and gets an administrator console.

👾 No signs of exploitation in the wild yet.

Qualys has introduced Agentic AI, a solution for autonomous cyber risk management

Qualys has introduced Agentic AI, a solution for autonomous cyber risk management. As part of this solution, Qualys provides ready-to-use Cyber Risk Agents that operate autonomously and act as an additional skilled digital workforce. Agentic AI not only detects issues and provides analytics but also autonomously identifies critical risks, prioritizes them, and launches targeted remediation workflows.

Available agents on the marketplace:

🔹 Identification and prioritization of risks related to external attacks
🔹 Adaptive cloud risk assessment
🔹 Audit readiness evaluation and reporting
🔹 Threat-based risk prioritization
🔹 Autonomous “Microsoft Patch Tuesday” cycle
🔹 Self-Healing agent for vulnerability management

They also introduced the Cyber Risk Assistant – a guided interface that transforms risk data into context-aware actions with autonomous execution.
