A security issue and some vulnerabilities have been discovered in ezContents, which can be exploited by malicious people to disclose sensitive information, conduct SQL injection attacks and bypass certain security restrictions.

1) Input passed to the "gsLanguage" and "language_home" parameters in diary/showdiary.php, "admin_home", "gsLanguage", and "language_home" in diary/showdiarydetail.php, "gsLanguage" and "language_home" in diary/submit_diary.php, "admin_home" in news/news_summary.php, and "nLink", "gsLanguage", and "language_home" in news/inlinenews.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks and URL-encoded NULL bytes. All scripts are located in the "modules/" directory.

Successful exploitation requires that "register_globals" is enabled - not the setting recommended in the installer - and that "magic_quotes_gpc" is disabled.

2) Input passed via the "login" parameter to admin/adminlogin.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

3) Input passed via various parameters to multiple scripts is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

http://[host]/showcontents.php?groupname=[code]
http://[host]/showcontents.php?subgroupname=[code]
http://[host]/showcontents.php?topgroupname=[code]

4) The security issue is caused due to the application allowing unrestricted access to the comments.php script. This can be exploited to insert arbitrary comments.

NOTE: Other scripts are reportedly also affected.

The vulnerabilities are confirmed in version 2.0.3. Other versions may also be affected.
