About this tag
The RADIUS tag on WindowsForum.com covers discussions about the Remote Authentication Dial-In User Service protocol as it relates to network security, authentication, and vulnerabilities. Topics include RADIUS exploitation in state-sponsored attacks on core routers, critical vulnerabilities like CVE-2025-20265 in Cisco FMC allowing pre-auth RCE when RADIUS is enabled, and integration guides for two-factor authentication with Meraki VPN using RADIUS. Older content addresses denial-of-service flaws in Microsoft's Network Policy Server RADIUS implementation (MS15-007). The tag also touches on captive portal setups using RADIUS for guest Wi-Fi authentication. These threads reflect RADIUS's role in enterprise authentication, security hardening, and patch management.
