eFront multiple vulnerabilities
Posted on 31 October 2011.
Multiple vulnerabilities have been reported in eFront, according to Secunia. These 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.
