I. DESCRIPTION

Input passed to the "st" and "keywords" parameters in "ikonboard.cgi" is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Result:
Ikonboard CGI Error 
-----------------------------------------------------------------------
Ikonboard has exited with the following error: 

Can't query the data from 'forum_posts' Reason: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '', 20'

This error was reported at: line 1 Query: SELECT * FROM iB313_forum_posts WHERE TOPIC_ID = '13066' AND QUEUED <> '1' ORDER BY POST_DATE ASC LIMIT 1', 20 

Please note that your 'real' paths have been removed to protect your information.

2) SQL injection in "keywords" parameter

Example:
http://host/support/ikonboard.cgi?act=Search&CODE=01&keywords='&type=name&forums=all&search_in=all&prune=0

Result:
Ikonboard CGI Error 
-----------------------------------------------------------------------
