MailChimp’s Login, Olark, Kaneva Sign-in Page Unvalidated Redirects and Forwards 0day Vulnerability










 






 

MailChimp, Olark, Kaneva online websites have computer cyber security bug problems. They can be exploited by Open Redirect (Unvalidated Redirects and Forwards) attacks. Here is the description of Open Redirect: "A web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a Redirect. This simplifies phishing attacks. An http parameter may contain a URL value and could cause the web application to  redirect the request to the specified URL. By modifying the URL value to a malicious site, an attacker may successfully launch a phishing scam and steal user credentials. Because the server name in the modified link is identical to the original site, phishing attempts have a more trustworthy appearance." (From CWE)


 

 

 

(1) MailChimp’s Login Page Open Redirect Vulnerability

Poc Video:
The vulnerability exists at “http://login.mailchimp.com/?” page with “referrer” parameter, e.g.
http://login.mailchimp.com/?referrer=http://google.com [1]

When a user clicks the URL ([1]) before login, the MailChimp “login page” appears. The user needs to enter his/her username and password. When this is done, the user could be redirected to a webpage different from MailChimp.
