Some vulnerabilities have been reported in Theeta CMS, which can be exploited by malicious people to conduct cross-site scripting, cross-site request forgery, and SQL injection attacks.

1) Input passed via the "start" parameter to blog/index.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

NOTE: This may further be used to conduct cross-site scripting attacks via SQL error messages.

2) 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. change the site configuration by tricking an administrative user into visiting a malicious web site.

NOTE: This may further be exploited to conduct script insertion attacks.

3) Input passed via the "blogid" parameter to userblogs/userarticle.php 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 "start" parameter to userblogs/userarticle.php (when "blogid" is set) is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities are reported in version 0.01. Other versions may also be affected.
