Some vulnerabilities have been discovered in Battle.net Clan Script, which can be exploited by malicious users to compromise a vulnerable system, and by malicious people and malicious users to conduct SQL injection attacks.

1) Input passed to the "showmember" parameter in members.php through index.php when the "page" parameter is set to "members" is not properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

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

2) Input passed to the "thread" parameter in index.php (when "page" is set to "board") is not properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of this vulnerability allows e.g. retrieval of administrator usernames and password hashes, but requires valid user credentials.

3) A vulnerability is caused due to missing restrictions on what file types that users are allowed to upload in admin.php (when "edit_page" is set to "medals"). This can be exploited to execute arbitrary PHP code.

Successful exploitation of this vulnerability requires valid administrator credentials (but see #2).

The vulnerabilities are confirmed in version 1.5.3. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised. Grant administrator access to trusted users only.
