https://suitecrm.com/  
  
  
[-] Affected Versions:  
  
Version 7.11.11 and prior versions.  
  
  
[-] Vulnerabilities Description:  
  
1) The vulnerability exists because the   
"EmailsControllerActionGetFromFields::getEmailSignatures()” method  
is using the unserialize() function with the "account_signatures” user   
preference, and such a value can be  
arbitrarily manipulated by evil users through the EmailUIAjax interface.   
This can be exploited to inject  
arbitrary PHP objects into the application scope, allowing an attacker   
to perform a variety of attacks,  
such as executing arbitrary PHP code.  
  
2) The vulnerability exists because the   
"EmailsControllerActionGetFromFields::handleActionGetFromFields()”  
method is using the unserialize() function with the "showFolders” user   
preference, and such a value can be  
arbitrarily manipulated by evil users through the EmailUIAjax interface.   
This can be exploited to inject  
arbitrary PHP objects into the application scope, allowing an attacker   
to perform a variety of attacks,  
such as executing arbitrary PHP code.
