Bonjour
Une faille possible a été détecté dans mon site
Voici le htacesss que j'utilise
que j'aimerai modifier pour colmater cette brèche ... sur la fonction de recherche apparemment ...
Avez vous des suggestions à me faire ?
Note : le site où la faille a été détecté a était réalisé avec joomla 3 ?
Merci d'avance

Recommended Solution:
* SQL Injection:
Use stored procedures to prevent attackers from altering the queries, and filter user input to discard invalid characters such as '
* Cross Site Scripting:
Filter user input to discard characters such as < and >. Make sure your server does not display error messages that contain input received from the user.
* Source Disclosure:
Make sure all debugging information is turned off from production servers. Scripts should be configured to be executables only, with no ability for a user to view them.
* Non-SSL login:
All login pages should be SSL protected (e.g. have an https:// link). When using non-SSL protected pages eavesdroppers might be able to capture usernames and passwords
* Sensitive information sent over non-encrypted page:
Make sure all sensitive information is sent over SSL-protected pages.
