Risk Analysis
This improper access control vulnerability in Windows Remote Access Connection Manager allows an authorized attacker to elevate privileges locally. Its inclusion in CISA's KEV catalog and active exploitation in the wild make it a critical concern, despite the lack of specific CVSS scores. The high EPSS score further emphasizes the urgency.
This vulnerability is actively being exploited in the wild and is listed in CISA's Known Exploited Vulnerabilities catalog. It allows an authorized local attacker to elevate privileges.
Apply all available security updates and patches for Microsoft Windows to address this privilege escalation vulnerability. Implement the principle of least privilege for all user accounts.
Technical Analysis
CVE-2025-59230 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2025-59230 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
