Description:
Some vulnerabilities have been discovered in Aztek Forum, which can be exploited by malicious people to conduct script insertion and SQL injection attacks or by malicious users to disclose potentially sensitive information.
1) Input passed in the message body when posting a new message isn't properly sanitised before being saved. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site when the user clicks on the "Citer" or "Editer" button when viewing the message.
Example:
</textarea>'"><script>[code]</script>
2) Input passed to the "login" parameter in "myadmin.php" isn't properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
3) Input passed to the "fid" cookie in various pages is not properly sanitised before being used in an SQL query in forum/load.php. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
4) Data in the "top_url" setting of forums is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources.
In combination with the file upload functionality, this can be exploited to execute arbitrary PHP code, but requires administrative privileges (which could be gained by using vulnerability #3).
The vulnerabilities are confirmed in version 4.0. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly sanitised and verified. Use another product.
