    IIS 5/6 vulnerability - Hackers actively exploring possible attacks (971492)

      While this new security issue pertains to corporate users rather than home users, please always use safe practices in visiting any website. Until a patch emerges, it is important for Web Admins to take mitigating actions as it could provide a new source for website attacks.

      Hackers are actively exploring this vulnerability and CERT has noted possible attacks for the new IIS vulnerability. While there is no current patch, there are ways of mitigating this (e.g., disabling WebDAV if no applications use it, greater restrictions on anonymous accounts, etc).
