Brendan Coles has discovered a weakness and some vulnerabilities in SugarCRM, which can be exploited by malicious users to conduct script insertion attacks, disclose sensitive information, and conduct SQL injection attacks and by malicious people to disclose certain system information.

1) The application discloses the full installation path via the cache/include/externalAPI.cache.js file.

Successful exploitation requires the completion of the user wizard by any user.

2) Input passed via a file to index.php (when "module" is set to "Documents" and "action is set to "Save" or when when "module" is set to "Notes" and "action is set to "Save") is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site if malicious data is viewed.

3) The application discloses the password hashes of users via JSON queries to index.php (when "entryPoint" is set to "json_server").

4) Input passed via the "group" JSON parameter to index.php (when "entryPoint" is set to "json_server") is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities are confirmed in version 6.5.2. Prior versions may also be affected.

Solution
Update to version 6.5.3.
