Well, actually it's quite simple.
With simple tools ( spreaded on the internet ) everyone can make himself/herself admin, and using all admin-commands, on any server.

This is a huge problem and requires fixes/updates as soon as possible.

At last this...

I noticed this security problem by myself when suddenly a young man of my old clan ( AE/ or AlterEgo ) hacked and flooded my server for an undefinable reason. It's dreadfull, it sickens my heart, that programs made by scum now are used by players of wellknown clans to hack servers.

are you sure he didn't just... guess the pass?

Nope.
I changed the adminpass ( to something he would never be able to guess )in soldat.ini a few hours before his arrival.
