SugarCRM REST Unserialize PHP Code Execution

Description

This module exploits a PHP Object Injection vulnerability in SugarCRM CE <= 6.5.23 which could be abused to allow unauthenticated users to execute arbitrary PHP code with the permissions of the webserver. The dangerous unserialize() call exists in the '/service/core/REST/SugarRestSerialize.php' script. The exploit abuses the __destruct() method from the SugarCacheFile class to write arbitrary PHP code into the /custom directory.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/unix/webapp/sugarcrm_rest_unserialize_exec
msf exploit(sugarcrm_rest_unserialize_exec) > show targets
    ...targets...
msf exploit(sugarcrm_rest_unserialize_exec) > set TARGET < target-id >
msf exploit(sugarcrm_rest_unserialize_exec) > show options
    ...show and set options...
msf exploit(sugarcrm_rest_unserialize_exec) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
