4) Description of Vulnerability

Secunia Research has discovered two vulnerabilities in the CKForms
component for Joomla, which can be exploited by malicious people to
conduct SQL injection attacks.

1) Input passed via the "articleid" parameter to index.php (when
"option" is set to "com_ckforms", "view" is set to "ckforms", "task"
is set to "send", and "id" is set to a valid form id) is not properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that the "Save result" is enabled in
the form's configuration (disabled by default).

2) Input passed via the "sortd" parameter to index.php (when "option"
is set to "com_ckforms", "view" is set to "ckformsdata", "layout" is
set to "data", and "id" is set to "f") is not properly sanitised
before being used in a SQL query. This can be exploited to manipulate
SQL queries by injecting arbitrary SQL code.
