As a penetration testers, we rarely have to find ‘zero day’ vulnerabilities or perform ‘bug hunting’ in order to compromise Windows Active Directory Domains. However, in one of these rare cases while performing an internal penetration test for a client, we had to do so.  Lansweeper is an inventory software that scans your network in order to gather system information such as patch level, network interfaces, resources status, etc.   We were fairly surprised during this test when we were able to access Lansweeper 5's dashboard with a regular user account.

As a follow-up to the conference given at Confoo few weeks ago, we are doing a focus article on the same topic. The presentation was giving an overview of the modern XSS attack vectors and filter bypass. In this blog post, we will take a closer look at XSS in the context of .NET applications.
