securfrog has discovered some vulnerabilities in TikiWiki, which can be exploited by malicious people to disclose certain sensitive information and to conduct cross-site scripting attacks.
1) The problem is caused due to the application returning system variables in SQL error messages. This can be exploited to disclose the database username and password, and the full installation path e.g. by omitting the "sort_mode" parameter in various scripts or via a large value of the "ver" parameter in tiki-wiki_rss.php.
2) Input passed to the "url" parameter in tiki-featured_link.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.
The vulnerabilities are confirmed in version 1.9.5 on PHP5. Other versions may also be affected.
