: KSES as well as a couple of other issues, so 30995 would seem to be a 
: dup.

BID 30995 is for multiple remote file inclusions in Moodle and references 
the milw0rm exploit under 'exploit' (well, not reference, copies the code 
from?). I assume this is KSES based code based on the /lib/kses.php 

BID 28599 is for kses multiple input validation vulns, but the discussion 
covers XSS and references previous BID 28424 and 28121.

OSVDB 43677 covers the XSS weakness, but we didn't have an entry for the 
RFI (and to confirm, the $injection_points array is for each unique script 
vulnerable right?). We will make one to cover this and cross-ref Milw0rm 
6356 / BID 30995.

Based on the two BIDs, they don't seem to be a dupe to me though as one is 
for RFI, the other for XSS?
