The remote Windows host is running a version of the Microsoft ASP.NET Framework that has multiple vulnerabilities.  These include:

  - A flaw exists in the way ASP.NET generates hash tables     for user-supplied values.  By sending a small number of     specially crafted posts to an ASP.NET server, an     attacker can take advantage of this flaw to cause a     denial of service condition.  (CVE-2011-3414)

  - The Framework does not properly validate return URLs     during the forms authentication process, which could     allow an attacker to redirect a victim to a malicious     website. (CVE-2011-3415)

  - ASP.NET forms authentication contains a vulnerability     that could allow an attacker that already has a     registered user on an application to gain the     privileges of another known user. (CVE-2011-3416)

  - An elevation of privilege vulnerability exists in the     way that ASP.NET Framework handles cached content when     Forms Authentication is used with sliding expiry.  An     attacker can take advantage of this vulnerability to     execute code in the context of a target user by     tricking the user into visiting a specially crafted     link. (CVE-2011-3417)
