ItWasAllADream - A PrintNightmare (CVE-2021-34527) Python Scanner.

项目说明

It Was All A Dream

A C (a.k.a PrintNightmare) Python Scanner. Allows you to scan entire subnets for the PrintNightmare RCE (not the LPE) and generates a CS with the results. Tests exploitability over MS-PAR and MS-RPRN.

This tool has "de-fanged" of the Python exploits, it does *not* actually exploit the hosts however it does use the same RPC calls used during exploitation to determine if hosts are .

Update July 7th 2021: This also checks if host(s) are using the UNC bypass discovered by

Why?

PO to determine if something is to PrintNightmare:

!cons

At the time of writing, the amount of that determine if a machine is is crazy and confusing.

Alternatives

Installation

~~This tool currently needs cube0x0's Impacket fork containing the MS-PAR implementation necessary for one of the checks. This change has been submitted to Impacket in this pull request.~~

You need to install Impacket from git as it has the MS-PAR implementation necessary for one of the checks. (Both of the installation methods below do this automatically for you)

Docker:

De requires Poetry:

Usage

As the exploit requires you to be authenticated to Acti, you need to supply credentials. If the password isn't supplied it will prompt you to enter it.

By default it will use 100 threads, you can increase/decrease these using the -t argument.

After its done you'll see a report_<timestamp>.csv file in your current directory with the results.
