Microsoft: ISA Vulnerability Could Allow Internet Content Spoofing

Thanking two Dutch developers, Martijn de Vries and Thomas de Clerk of Info Support for discovering and reporting it, Microsoft yesterday sent out a Security Alert about what it called a "Spoofing Vulnerability" in Microsoft Internet Security and Acceleration Server 2000 (ISA Server) and Microsoft Proxy Server 2.0 that could enable an attacker to spoof trusted Internet content.

ISA Server is an enterprise-level firewall and Web cache server. Proxy Server 2.0 acts as an Internet gateway for computers on a network. Users of the software listed below need to download and install an update:

  • Internet Security and Acceleration Server 2000 Service Pack 1 (SP1)
  • Internet Security and Acceleration Server 2000 SP2
  • Microsoft Small Business Server 2000 (includes Internet Security and Acceleration Server 2000)
  • Microsoft Small Business Server 2003 Premium Edition (includes Internet Security and Acceleration Server 2000)
  • Microsoft Proxy Server 2.0 SP1

    Pity the poor SMBs whose businesses have been affected by spoofing and phishing scams recently. How much is MS to blame? Or is it just a generic problem right now?
