DESCRIPTION:
Multiple vulnerabilities have been reported in eFront, which can be
exploited by malicious users to conduct SQL injection attacks and
compromise a vulnerable system and by malicious people to bypass
certain security restrictions, conduct cross-site scripting and SQL
injection attacks, and compromise a vulnerable system.

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 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.

3) 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.

4) Input passed via the "HTTP_REFERER" parameter to
www/periodic_updater.php is not properly sanitised before being used
in a SQL query. This can be exploited to manipulate SQL queries by
injecting arbitrary SQL code.

5) Input passed via the "view_unit" parameter to
www/js/LMSFunctions.php is not properly sanitised before being used
in a SQL query. This can be exploited to manipulate SQL queries by
injecting arbitrary SQL code.

6) Input passed via the "sent_notification_id" parameter to
www/send_notifications.php is not properly sanitised before being
used in a SQL query. This can be exploited to manipulate SQL queries
by injecting arbitrary SQL code.

Successful exploitation requires that the server is configured to
send emails externally.

7) Certain unspecified input is not properly sanitised before being
used in a SQL query. This can be exploited to manipulate SQL queries
by injecting arbitrary SQL code.

8) Input passed via the "surveys_ID" and "screen_survey" parameters
to professor.php (when "ctg" is set to "survey") is not properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

9) An error within the authentication mechanism does not properly
verify the "cookie_login" cookie value. This can be exploited to
bypass the authentication mechanism and gain administrative access to
the application.

10) Input passed via the "templateName" POST parameter is not
properly verified in
www/editor/tiny_mce/plugins/save_template/save_template.php before
being used to create files. This can be exploited to create arbitrary
files outside of the web root via directory traversal attacks and
URL-encoded NULL bytes.

11) The libraries/filesystem.class.php script does not properly
verify uploaded files. This can be exploited to execute arbitrary PHP
code by uploading a malicious PHP script with a capitalised
extension.

Successful exploitation requires "Professor" privileges.

The vulnerabilities are reported in version 3.6.10 build 11944. Prior
versions may also be affected.

SOLUTION:
Update to version 3.6.10 build 12151 or later.
