eFront Multiple Cross-Site Scripting and Script Insertion Vulnerabilities

Description

Multiple vulnerabilities have been discovered in eFront, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to conduct cross-site scripting attacks.
1) Input passed via the "user" parameter to www/administrator.php is not properly sanitised in 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.
This vulnerability is confirmed in version 3.6.14 build 18016. Other versions may also be affected.
2) Input passed via the URL to www/index.php is not properly sanitised in www/themes/default/templates/includes/blocks/login.tpl, www/themes/default/templates/includes/header_code.tpl, www/themes/default/templates/includes/blocks/cart.tpl, libraries/direction.class.php, www/themes/default/templates/index.tpl, and www/themes/default/templates/includes/closing.tpl 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 e.g. via the "title" parameter to student.php (when "ctg" is set to "forum""type" is set to "topic", and "edit" is set to a valid forum value) and e.g. via the "poll_subject" parameter to student.php (when "ctg" is set to "forum", "type" is set to "poll", and "edit" is set to a valid forum value) is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site if malicious data is viewed.
The vulnerabilities #2 and #3 are confirmed in version 3.6.10 build 12151. Other versions may also be affected.
4) Input passed via the first name within a profile of a user is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site if malicious data is viewed.
This vulnerability is confirmed in version 3.6.14 build 18016. Other versions may also be affected.
