Multiple vulnerabilities have been discovered in SocialCMS, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to conduct cross-site request forgery and SQL injection attacks and compromise a vulnerable system.

1) The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. create an administrative user by tricking an administrator into visiting a malicious web site while being logged-in to the application.

2) Input passed via the "category" POST parameter to search.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.

3) Input passed via the "TR_title" parameter to my_admin/admin1_list_pages.php 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 when the malicious data is being viewed.

Successful exploitation of this vulnerability requires the "admin1_list_pages.php" permission.

4) An error exists due to the TinyMCE/tinymce/jscripts/tiny_mce/plugins/ibrowser/ibrowser.php script improperly validating uploaded files. This can be exploited to execute arbitrary PHP code by uploading a PHP file with e.g. an appended ".gif" file extension.

Successful exploitation of this vulnerability requires that Apache is not configured to handle the mime-type for media files with e.g. a ".gif" extension (configured to handle by default).

The vulnerabilities are confirmed in version 1.0.2. Other versions may also be affected.
