Some vulnerabilities and a security issue have been reported in CMME (Content Management Made Easy), which can be exploited by malicious people to conduct cross-site scripting attacks, bypass certain security restrictions, and disclose sensitive information.

1) Input passed to the "env" parameter in index.php is not properly sanitised before being used. This can be exploited to display arbitrary files via directory traversal attacks and URL-encoded NULL bytes.

Successful exploitation of this vulnerability requires that "magic_quotes_gpc" is disabled.

2) The problem is that user credentials are stored in the "backup/cmme_data.zip" and "backup/cmme_cmme.zip" files inside the web root. This can be exploited to disclose usernames and password hashes.

Successful exploitation of this vulnerability requires that the administrator has used the "Make a backup" functionality.

3) Input passed to the "page" and "year" parameters in statistics.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.

The vulnerabilities and the security issue are confirmed in version 1.12. Other versions may also be affected.

4) An unspecified error exists within the xinha code, which can be exploited by malicious people to edit content without being properly logged in.
