Secunia Research has discovered two vulnerabilities in TaskFreak, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks.
1) Input passed to the "tznMessage" parameter in logout.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.
2) Input passed via the "password" parameter to login.php (when "username" is set to a valid user) is not properly sanitised before being used in a SQL query in include/classes/tzn_user.php. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation allows bypassing the authentication mechanism, but requires that "magic_quotes_gpc" is disabled.
The vulnerabilities are confirmed in version 0.6.3. Prior versions may also be affected.
