Subject: MODX SQLi from oss-sec

The author of the email to the oss-sec says he isn't sure if the linked
commit fixes the issue and it should.

You can exploit this possibly using a blind time or boolean sqli. This is
me just playing around after doing some code analysis. Possibly other
connectors are affected? No idea about whether authentication will be
needed for all vectors, but in my cursory testing it needed at least a
PHPSESSID cookie (maybe just get first index to get anon PHPSESSID, who
knows).
