Multiple XSS in Hero Framework

High-Tech Bridge Security Research Lab discovered two XSS vulnerabilities in Hero Framework, which can be exploited to perform cross-site scripting attacks against vulnerable application.

1) Multiple XSS in Hero Framework: CVE-2013-2649
1.1 The vulnerability exists due to insufficient sanitisation of user-supplied data in "username" HTTP GET parameter passed to "/users/login" URL. A remote attacker can trick a logged-in user to open a specially crafted link and execute arbitrary HTML and script code in victim's browser in context of the vulnerable website.
The exploitation example below uses JavaScript 'alert()' function to display user's cookies:
http://[host]/users/login?username=%22%3E%3Cscript%3Ealert%28document.cookie %29;%3C/script%3E

1.2 The vulnerability exists due to insufficient sanitisation of user-supplied data in "error" HTTP GET parameter passed to "/users/forgot_password" URL. The parameter is passed to the vulnerable script in base64 encoding. A remote attacker can trick a logged-in user to open a specially crafted link and execute arbitrary HTML and script code in victoms's browser in context of the vulnerable website.
The exploitation example below uses the same XSS payload as above encoded in base64 to display user's cookies:
http://[host]/users/forgot_password?error=PHNjcmlwdD5hbGVydChkb2N1bWVudC5jb2 9raWUpOzwvc2NyaXB0Pg==
