Syncovery For Linux Web-GUI Session Token Brute-Forcer

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.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
