[ NOSpamPTI Wordpress plugin Blind SQL Injection ]
*
[ Vendor product description ]
*
NOSpamPTI eliminates the spam in your comment box so strong and free,
developed from the idea of Nando Vieira <a href="http://bit.ly/d38gB8"
rel="nofollow">http://bit.ly/d38gB8</a>, but some themes do not support
changes to the functions.php to this we alter this function and
available as a plugin. Make good use of this plugin and forget all the Spam.
*
[ Bug Description ]
*
NOSpamPTI contains a flaw that may allow an attacker to carry out a
Blind SQL injection attack. The issue is due to the wp-comments-post.php
script not properly sanitizing the comment_post_ID in POST data. This
may allow an attacker to inject or manipulate SQL queries in the
back-end database, allowing for the manipulation or disclosure of
arbitrary data.
