DOUBLEPULSAR RCE 2: An RDP Story
In this sequel, wvu [https://github.com/wvu-r7] recounts the R&D (in all its
imperfect glory) behind creating a Metasploit module for the DOUBLEPULSAR

SMB variant, you can read our blog post
[/2019/10/02/open-source-command-and-control-of-the-doublepulsar-implant/]
detailing how we achieved RCE with it.

Silly admin, Citrix is for script kiddies
A hot, new module [https://github.com/rapid7/metasploit-framework/pull/12816]

CVE-2019-19781 which is a directory traversal vulnerability in Citrix
Application Delivery Controller (ADC) and Gateway. This exploit takes advantage
of unsanitized input within the URL structure of one of the API endpoints to
access specified directories. Conveniently there is a directory available that

A new OpenBSD local exploit
Community contributor bcoles [http://github.com/bcoles] brings us a new exploit
module for CVE-2019-19726, a vulnerability originally discovered by Qualys

a local web server. Since it does not write anything on target’s disk, payloads
are less likely to be caught by anti-virus protections. However, since Microsoft
