Microsoft Internet Security and Acceleration (ISA) Server 2006 Gold and SP1, when Radius OTP is enabled, uses the HTTP-Basic authentication method, which allows remote attackers to gain the privileges of an arbitrary account, and access published web pages, via vectors involving attempted access to a network resource behind the ISA Server, aka "Radius OTP Bypass Vulnerability."

Security readout for executives and security teams

This flaw affects Microsoft ISA Server 2006 Gold and SP1 when Radius OTP is enabled. The server may use HTTP Basic authentication in a way that lets a remote attacker access published web pages as an arbitrary account. Treat exposed ISA deployments using Radius OTP as a serious access-control risk. Exposure is likely limited to legacy ISA Server 2006 Gold or SP1 deployments using Radius OTP and publishing internal web pages. The source bundle does not identify other affected products, versions, or CPEs. Prioritize remediation if ISA Server 2006 with Radius OTP still protects business web applications. The issue can undermine authentication at the perimeter, but urgency depends on whether this legacy configuration remains deployed. Mitigation focus: Follow Microsoft MS09-031 guidance for affected ISA Server deployments.; Inventory ISA Server 2006 Gold and SP1 systems still in use.; Identify whether Radius OTP is enabled on any ISA publishing rules..
