XSS and CSRF Vulnerabilities in Gutuma

Name :  XSS & CSRF Vulnerabilities in Gutuma
Software :  Gutuma 1.6 and possibly below.
Vendor Homepage :
Vulnerability Type :  XSS & CSRF
Severity :  Critical
Researcher :  Omar Kurt
Advisory Reference :  NS-13-010


Gutuma was born out of the need for free mailing list / newsletter software that is geared, not towards mass-marketing companies and spammers, but web developers who need a system that can be easily integrated with an existing web site. It's very easy to install and use, and doesn't even require a database, but it still has lots of powerful features. Internally, Gutuma uses the tried and tested Swift mailer for sending messages, and the SACK library for AJAX subscribe requests.


Gutuma is affected by XSS and CSRF vulnerabilities in version 1.6. Example PoC’s are as follows:

  • XSS 
    POST - param:
  • CSRF
    It’s possible to change administrator’s password, email or username
    Form Name: edit_form
