Secunia

Janek Vind has reported some vulnerabilities in SugarCRM, which can be exploited by malicious users to conduct SQL injection attacks, bypass certain security restrictions, and compromise a vulnerable system.

1) Input passed via the "current_query_by_page" parameter to multiple scripts is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Examples:
http://[host]/index.php?module=Project&action=index&Project2_PROJECT_offset=1&current_query_by_page=[code]
http://[host]/index.php?module=Opportunities&action=index&Opportunities2_OPPORTUNITY_offset=1&current_query_by_page=[code]
http://[host]/index.php?module=Project&action=index&Project2_PROJECT_offset=1&current_query_by_page=[code]
http://[host]/index.php?module=Cases&action=index&Cases2_CASE_offset=1&current_query_by_page=[code]
http://[host]/index.php?module=Bugs&action=index&Bugs2_BUG_offset=1&current_query_by_page=[code]
http://[host]/index.php?module=Tasks&Tasks2_TASK_offset=1&current_query_by_page=[code]
http://[host]/index.php?module=Meetings&action=index&return_module=Meetings&return_action=DetailView&Meetings2_MEETING_offset=1&current_query_by_page=[code]
http://[host]/index.php?module=Calls&action=index&return_module=Calls&return_action=DetailView&Calls2_CALL_offset=1&current_query_by_page=[code]
http://[host]/index.php?module=Notes&action=index&return_module=Notes&return_action=DetailView&Notes2_NOTE_offset=1&current_query_by_page=[code]

2) The application does not properly restrict access to the delete functionality, which can be exploited to delete arbitrary files from the webroot of the application.

3) Input passed via the "file" parameter to index.php (when "entryPoint" is set to "HandleAjaxCall" and "method" is set to "performInstall") is not properly sanitised before being used to include files. This can be exploited to include arbitrary files from local and remote resources.

4) The application does not properly restrict access to the Backup functionality, which can be exploited to create and download backup files.

5) The application does not properly restrict access to the "Upgrade Wizard" functionality, which can be exploited to execute arbitrary PHP code by uploading a PHP file compressed in ZIP format.

6) An error in the .htaccess file when SugarCRM is installed on the Windows platform can be exploited to access files directly via uppercase characters.

The vulnerabilities are reported in versions 5.2.0j and 5.5.0.RC2. Other versions may also be affected
