Multiple vulnerabilities have been reported in Joomla!, which can be exploited by malicious people to conduct cross-site scripting attacks, disclose sensitive information, and bypass certain security restrictions.
1) Certain unspecified input 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.
2) Certain unspecified improper error checks can be exploited to disclose certain information.
3) Certain improper permission checks can be exploited to gain unauthorised access.
4) Input appended to the URL after index.php (when "option" is set to "com_contact", "view" is set to "category" or "featured", and "id" is set) 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.
5) Input appended to the URL after index.php (when "option" is set to "com_content", "view" is set to "category", and "id" is set) 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.
6) Input appended to the URL after index.php (when "option" is set to "com_newsfeeds", "view" is set to "category", and "id" is set) 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.
7) Input passed via the "option" parameter to index.php is not properly sanitised in templates/beez5/error.php or templates/beez_20/error.php 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.
8) Input passed via the "searchword" POST parameter to index.php (when "option" is set to "com_search" and "task" is set to "search") 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.
Successful exploitation of this vulnerability requires that the victim is running Internet Explorer or Konqueror.
The vulnerabilities are reported in versions 1.6.3 and prior.
