Synopsis :

The version of the .NET Framework installed on the remote host is
affected by multiple vulnerabilities.

Description :

The remote Windows host is running a version of the Microsoft .NET
Framework that is affected by multiple vulnerabilities :

- A spoofing vulnerability exists that could allow an
attacker to modify the contents of an XML file without
invalidating the signature associated with the file.
(CVE-2013-1336)

- An authentication bypass vulnerability exists because of
the way the Microsoft .NET framework improperly creates
policy requirements for authentication when setting up
WCF endpoint authentication. A remote attacker who
exploited this vulnerability may be able to steal
information or take actions in the context of an
authenticated user. (CVE-2013-1337)
