4) Description of Vulnerability

Secunia Research has discovered multiple vulnerabilities in the Mingle
Forum plugin for WordPress, which can be exploited by malicious users
and malicious people to conduct SQL injection attacks.

1) Input passed via the "id" parameter to index.php (when "page_id"
is set to a valid forum page id, "mingleforumaction" is set to
"viewtopic", "t" is set to e.g. "1.0", and "remove_post" is set) is
not properly sanitised in wp-content/plugins/mingle-forum
/wpf.class.php before being used in a SQL query.This can be exploited
to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed via the "id" parameter to index.php (when "page_id"
is set to a valid forum page id, "mingleforumaction" is set to
"viewtopic", "t" is set to e.g. "1.0", and "sticky" is set) is not
properly sanitised in wp-content/plugins/mingle-forum/wpf.class.php
before being used in a SQL query. This can be exploited to manipulate
SQL queries by injecting arbitrary SQL code.

3) Input passed via the "id" parameter to index.php (when "page_id"
is set to a valid forum page id, "mingleforumaction" is set to
"viewtopic", "t" is set to e.g. "1.0", and "closed" is set) is not
properly sanitised in wp-content/plugins/mingle-forum/wpf.class.php
before being used in a SQL query. This can be exploited to manipulate
SQL queries by injecting arbitrary SQL code.

"page_id" is set to a valid forum page id and "mingleforumaction" is
set to "postreply") is not properly sanitised in wp-content/plugins
