THis is PoC version
to run:
$ git clone https://github.com/CoolerVoid/raptor_waf
$ cd raptor_waf; make; bin/raptor
#Note:
Don't execute with "cd bin; ./raptor" use full path "bin/raptor" look detail https://github.com/CoolerVoid/raptor_waf/issues/4
Need lib pcre to compile.
Example
Up some HTTPd server at port 80
redirect with raptor to port 8883
$ bin/Raptor -h localhost -p 80 -r 8883 -w 4 -o loglog.txt
Copy vulnerable PHP code to your web server directory
$ cp doc/test_dfa/test.php /var/www/html
Now you can test xss attacks at
http://localhost:8883/test.php
Other option to run(now with regex, look file config/regex_rules.txt to edit rules):
$ bin/Raptor -h 127.0.0.1 -p 80 -r 8883 -w 0 -o resultwaf -m pcre
