Description:
Some vulnerabilities have been discovered in Lasernet CMS, which can be exploited by malicious people to conduct SQL injection attacks.

1) Input passed to the "new" parameter in index.php (when "id" is set to "new") is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is disabled.

2) A vulnerability is caused due to an error related to FCKEditor. This can be exploited to e.g. upload malicious files and execute arbitrary PHP code.

This may be related to:
SA27123

Successful exploitation requires that the uploader is enabled.

The vulnerabilities are confirmed in version 1.11 and reported in version 1.5. Other versions may also be affected.

Solution:
Edit the source code to ensure that input is properly sanitised. Disabled the file upload functionality.
