pre-authentication

About this tag
Pre-authentication refers to security mechanisms that require authentication before granting access to resources or services. On WindowsForum.com, discussions cover vulnerabilities in pre-authentication implementations, such as CVE-2025-10127 in Daikin Security Gateways allowing unauthenticated password resets, and CVE-2025-20265 in Cisco FMC enabling remote code execution via RADIUS. Azure App Proxy misconfigurations can bypass pre-authentication, exposing on-premises apps. Kerberos pre-authentication issues in Windows 7 and Server 2008 R2 cause logon errors, including RC4 failures for the Network Service account. These topics highlight the importance of proper pre-authentication configuration to prevent unauthorized access and attacks.
