Joomla! ALFContact Component Multiple Cross-Site Scripting Vulnerabilities


Description   Jose Carlos de Arriba has discovered multiple vulnerabilities in the ALFContact component for Joomla!, which can be exploited by malicious people to conduct cross-site scripting attacks.
1) Input passed to the "emailto_id" and "extravalue" parameters in index.php (when "option" is set to "com_alfcontact") 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 the victim user is running a browser which executes certain JavaScript statements from style tags (e.g. Internet Explorer 6).
2)Input passed to the "name", "email", and "subject" parameters in index.php (when "option" is set to "com_alfcontact") 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 1.9.3. Prior versions may also be affected.
