Description:
Some vulnerabilities have been discovered in A-Blog, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks, or to compromise a vulnerable system.
1) Input passed to various parameters in various files isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from external and local resources.
Successful exploitation requires that "register_globals" is enabled.
Affected by unverified "navigation_start" and "navigation_middle" parameters:
navigation/menu.php
navigation/donation.php
navigation/latestnews.php
navigation/links.php
Affected by unverified "navigation_end" parameter:
navigation/search.php
navigation/donation.php
Affected by unverified "open_box", "middle_box", and "close_box" parameter:
sources/myaccount.php
2) Input passed to the "words" parameter in search.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
3) Input passed to the "id" parameter in includes/news.inc.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The vulnerabilities are confirmed in version 2. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly sanitised and verified.
Set "register_globals" to "Off".
