4) Description of Vulnerability

Secunia Research has discovered three vulnerabilities in KaiBB, which 
can be exploited by malicious users to conduct SQL injection attacks.

1) Input passed via the "checkbox" POST parameter to index.php (when 
"s" is set to "viewtopic" and "delete_posts" and "confirmed" are set) 
is not properly sanitised in core/topic.php before being used in SQL 
queries. This can be exploited to manipulate SQL queries by injecting 
arbitrary SQL code.

Successful exploitation of this vulnerability requires a moderator 
account.

2) Input passed via the "checkbox" POST parameter to index.php (when 
"s" is set to "mail") is not properly sanitised in core/mail.php before 
being used in SQL queries. This can be exploited to manipulate SQL 
queries by injecting arbitrary SQL code.

Successful exploitation of  vulnerabilities #1 and #2 requires that 
"magic_quotes_gpc" is disabled.

3) Input passed via the "attachment" parameter when uploading a file 
through a webform is not properly sanitised in inc/function.php before 
being used in SQL queries. This can be exploited to manipulate SQL 
queries by injecting arbitrary SQL code.

Successful exploitation of this vulnerability requires permissions to 
upload files.
