Error saving in the entry section if there is a link (http://) + mod_security

  1. Hello (first, sorry for my poor english)

    When I try to modify any entries in my latest form I get an error 404. After few hours I have pinpoint 2 hint to help me resolve the bug but I cant go further with my knowledge :

    The first hint is quite simple : when I save a form with the following string "http://" the form send me to a 404 error and dosent save the form.

    The second hint came from my web host. I got blacklisted twice from his servers. After investigations we found out it was me who trigger the error each time I saved the entries.
    Here is the mod security log :

    /wp-admin/admin.php?page=gf_entries&view=entry&id=8&lid=235&filter=&paged=2&pos=28 HTTP/1.1

    Access denied with code 403 (phase 2). Match of "rx ://%{SERVER_NAME}/" against "ARGS:input_4" required. [file "/usr/local/apache/conf/modsec/10_asl_rules.conf"] [line "1216"] [id "340464"] [rev "54"] [msg " UNSUPPORTED DELAYED Rules: Remote File Injection attempt in ARGS (admin.php)"] [severity "CRITICAL"]

    As a quick fix I removed all the "http://" string in the form but it could be nice to get a good fix.

    By entries I mean the messages

  2. Your host needs to relax their mod_security rules to allow this normal form submission through. We've discussed this very topic a few times before:

    Please contact your host.

  3. Any hint on what to change on the server specificly? My host is really strict on security and wont just lower security in general....

  4. I'm afraid I am not familiar with the configuration of those mod_security rules. You can show them the error and have them allow that specific request through. It's a normal Gravity Forms function which is being prevented by the mod_security rules.
