Beskrivelse:
Der er rapporteret et sikkerhedsproblem i Microsoft Windows, som kan udnyttes af ondsindede personer til at udføre Man-in-the-Middle angreb.

Problemet skyldes, at WPAD-featuren søger efter "wpad" hostnavne op til "second-level" domæner, som potentielt er untrusted. Dette kan udnyttes til at udføre MitM-angreb mod "third-level" eller dybere domæner.

Succesfuld udnyttelse forudsætter f.eks. at systemet har et primært "DNS suffix" opsat (se producentens advisory for detaljer).

Løsning:
Producenten har foreslået diverse workarounds (se advisory for detaljer).

Rapporteret af / Kredit:
Producenten krediterer Beau Butler.
