So, I’m pretty sure I know what to do to get from foothold to the next user, but without write-privileges to that certain folder, I have no idea how to achieve this. A certain config setting of the m**** service disallows reading from/writing to that folder (and the “current other” user doesn’t have any privileges on that folder, too).
If anyone could give a nudge in the right direction (or point out my mistake), it would be much appreciated
Have a look to see if the attackers, or someone on the system, left something useful behind. Possibly in the built in tables.
DM me for more specific language because I appreciate the vagueness here might be confusing.
