Description

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

- An information disclosure vulnerability exists in the .NET Framework due to improper DTD parsing of crafted XML files. An unauthenticated, remote attacker can exploit this, via a malicious application file, to gain read access to the local files on the system.
(CVE-2015-6096)

- A cross-site scripting vulnerability exists in ASP.NET due to improper validation of values in HTTP requests.
An unauthenticated, remote attacker can exploit this to inject arbitrary script into the user's browser session.
(CVE-2015-6099)

- A security feature bypass vulnerability exists in the .NET Framework due to improper implementation of the Address Space Layout Randomization (ASLR) feature. An unauthenticated, remote attacker can exploit this, via crafted website content, to predict memory offsets in a call stack. (CVE-2015-6115)
