Initial Notes:

• The .NET Runtime Event Provider requires setting COMPLUS_ETWEnabled=1 in your process' environment.
• CLRConfig will look for configurations in the following places in the following order:
  • Look at environment variables (prepending COMPlus_ to the name)
  • Look at the framework registry keys (HKCU\Software\Microsoft\.NETFramework
  • Look at the framework registry keys HKLM\Software\Microsoft\.NETFramework)
• These can be set in the following ways:
  • Setting the environment variable COMPlus_:
• Windows

// A very rough x64 POC for spoofing environment variables similar to argument spoofing with a focus on
// setting the COMPlus_ETWEnabled=0 var for disabling ETW in .NET.
//
// Works by launching the target process suspended, reading PEB, updates the ptr used to store environment variables,
// and then resuming the process.

Completely based on @Flangvik netloader

This partial rewrite of @Flangvik Netloader includes the following changes:

	- Allow loading of an XOR encrypted binary to bypass antiviruses
		To encrypt the initial binary you can use my Python transformFile.py script.
		Example: ./transformFile.py -e xor -k mightyduck -i Rubeus.bin -o Rubeus.xor

This is a variation of the technique originally discovered by subtee and described here

TL;DR It essentially allows you to turn any .NET application into a lolbin by providing a configuration file and specifying the <appDomainManagerAssembly> element pointing to a specially crafted .NET assembly which executes when the application is loaded.

This variation allows you to load the AppDomainManager assembly from a UNC path or HTTP(s) server. Also disables ETW thanks to the <etwEnable> element :)

1. Copy some binary you love to say, C:\Test. Lets use aspnet_compiler.exe as an example
2. Compile test.cs to test.dll with a signed strong name, this is required to load an assembly outside of a .NET applications base directory.
3. Host test.dll on a remote SMB or HTTP(S) server

TLDR

Cisco Security Manager is an enterprise-class security management application that provides insight into and control of Cisco security and network devices. Cisco Security Manager offers comprehensive security management (configuration and event management) across a wide range of Cisco security appliances, including Cisco ASA Adaptive Security Appliances, Cisco IPS Series Sensor Appliances, Cisco Integrated Services Routers (ISRs), Cisco Firewall Services Modules (FWSMs), Cisco Catalyst, Cisco Switches and many more. Cisco Security Manager allows you to manage networks of all sizes efficiently-from small networks to large networks consisting of hundreds of devices.

Several pre-auth vulnerabilities were submitted to Cisco on 2020-07-13 and (according to Cisco) patched in version 4.22 on 2020-11-10. Release notes didn't state anything about the vulnerabilities, security advisories were not published. All payload are processed in the context of NT AUTHORITY\SYSTEM.
