Description

This module attempts to brute-force a valid session token for the Syncovery File Sync & Backup Software Web-GUI
by generating all possible tokens, for every second between 'DateTime.now' and the given X day(s).
By default today and yesterday (DAYS = 1) will be checked. If a valid session token is found, the module stops.
The vulnerability exists, because in Syncovery session tokens are basically just base64(m/d/Y H:M:S) at the time
of the login instead of a random token.
If a user does not log out (Syncovery v8.x has no logout) session tokens will remain valid until reboot.
