SolarPuTTYDecrypt

A post-exploitation/forensics tool to decrypt SolarPuTTY's sessions files

Author: Paolo Stagno (@Void_Sec - voidsec.com)

Intro:

In September 2019 I found some bad design choices (vulnerability?) in SolarWinds SolarPuTTY software. It allows an attacker to recover SolarPuTTY's stored sessions from a compromised system.

This vulnerability was leveraged to targets all SolarPuTTY versions <= 4.0.0.47

I've made this detailed blog post explaining the "vulnerability".

Usage:

By default, when runned without arguments, the tool attempts to dump the local SolarPuTTY's sessions file (%appdata%\SolarWinds\FreeTools\Solar-PuTTY\data.dat).

Otherwise the tool can be pointed to an arbitrary exported sessions file in the following way (use "" for empty password):

SolarPuttyDecrypt.exe C:\Users\test\session.dat Pwd123!

Sessions will be outputted on screen and saved into User's Desktop (%userprofile%\desktop\SolarPutty_sessions_decrypted.txt)

Help Needed

Searching for someone interested into helping me adding the decryption routine to the Metasploit post-exploitation module.
