Some vulnerabilities have been discovered in Mambo, which can be exploited by malicious people to conduct cross-site scripting, script insertion and SQL injection attacks.

1) Input passed to the "usercookie[password]" cookie parameter in includes/mambo.php (version 4.5.4) 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 "magic_quotes_gpc" is disabled.

Note: A weakness has also been reported, that allows users to change their passwords without knowing the old password. In combination these issues can be exploited to access the administration section.

The vulnerabilities are confirmed in version 4.5.4 with Security Patch 2, version 4.6, and version 4.6.1. Other versions may also be affected.

2) Input passed via the URL is not properly sanitised before it is 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.

Successful exploitation requires that the user is running a browser that has not URL-encoded the request (e.g. Internet Explorer).

3) Input passed to the "mcname" parameter when posting a comment is not properly sanitised before it is used. This can be exploited to insert limited HTML and script code, which will be executed in an administrative user's browser session in context of an affected site when the malicious data is viewed.

4) Input passed to the "mcname" parameter when posting a comment is also not properly sanitised before it is used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is disabled.

The vulnerabilities are confirmed in version 4.6.1. Other versions may also be affected.
