    Hello,

    after the update I get a notice like this:

    Notice: BPS Query String Exploits Code Changes
    Older BPS Query String Exploits code was found in BPS Custom Code. Several Query String Exploits rules were changed/added/modified in the root .htaccess file in BPS Pro 7.9 & 8.3.
    Copy the new Query String Exploits section of code from your root .htaccess file and paste it into this BPS Custom Code text box: CUSTOM CODE BPSQSE BPS QUERY STRING EXPLOITS and click the Save Root Custom Code button.
    This Notice will go away once you have copied the new Query String Exploits code to BPS Custom Code and clicked the Save Root Custom Code button.

    Here is my code in that section:

    EDIT/UPDATE:  the new security filter has been added/updated below

    # BEGIN BPSQSE BPS QUERY STRING EXPLOITS
    # The libwww-perl User Agent is forbidden - Many bad bots use libwww-perl modules, but some good bots use it too.
    # Good sites such as W3C use it for their W3C-LinkChecker. 
    # Use BPS Custom Code to add or remove user agents temporarily or permanently from the 
    # User Agent filters directly below or to modify/edit/change any of the other security code rules below.

    Looks like we forgot to update that Notice message.  “…Several Query String Exploits rules were changed/added/modified in the root .htaccess file in BPS Pro 7.9 & 8.3….” will be deleted from that Notice.

    The root .htaccess security rules that were changed are listed on the BPS Pro Whats New page in BPS Pro under the new Logs & Info main menu >>> Whats New page and also on the BPS Pro Release Dates / Whats New Topic >>> Whats New link.

    http://forum.ait-pro.com/forums/topic/bulletproof-security-pro-version-release-dates/

    Root .htaccess Security Filters Change:

    Old security filters

    RewriteCond %{THE_REQUEST} \?\ HTTP/ [NC,OR] 
    RewriteCond %{THE_REQUEST} \/\*\ HTTP/ [NC,OR]
    
    RewriteCond %{THE_REQUEST} \?+(%20{1,}|[^\s])+HTTP+(:/|/) [NC,OR] 
    RewriteCond %{THE_REQUEST} \/+(\*|%2a)+(%20|\s){1,}+HTTP+(:/|/) [NC,OR]
    

    New security filter – had some issues/problems and was changed again…

    RewriteCond %{THE_REQUEST} (\?|\*|%2a)+(%20+|\s+|%20+\s+|\s+%20+|\s+%20+\s+)HTTP(:/|/) [NC,OR]

    New security filter BPS Pro 9.1/BPS .50.4 – no known issues/problems

    RewriteCond %{THE_REQUEST} (\?|\*|%2a)+(%20+|\\s+|%20+\\s+|\\s+%20+|\\s+%20+\\s+)HTTP(:/|/) [NC,OR]

    [Forum Topic manually moved to this relevant Topic]

    I have a notice “Notice: BPS Query String Exploits Code Changes”, etc.

    Where exactly can I find the correct exploit code to put into the custom code section? The root.htaccess is generated using my custom code and I can’t find where to get the latest correct exploit code section.

    Thanks.

    You can either use the code posted above and add any additional customizations to the BPS Query String Exploits code that you have made or use the code above as a reference / comparison to your current BPS Query String Exploits code in BPS Custom Code and then edit it, resave it, click the activate Root folder BulletProof Mode again.

    The most recent root .htaccess code/rule change is this below:

    RewriteCond %{THE_REQUEST} (\?|\*|%2a)+(%20+|\\s+|%20+\\s+|\\s+%20+|\\s+%20+\\s+)HTTP(:/|/) [NC,OR]
