Subject: CVE-2014-6316: URL redirection issue in MantisBT

Greetings,

Please update CVE-2014-6316 with the information below


Description:

A bug in the URL sanitization routine allows an attacker to craft an URL 
that can redirect outside of the MantisBT instance's domain when the 
software is installed at the web server's root.

e.g. http://example.com/login_page.php?return=http://google.com will 
redirect to Google.

Affected versions:
=> 1.2.0a3, <= 1.2.17

Fixed in versions:
1.2.18 (not yet released)

Patch:
See Github [1]

Credit:

Redirection in login_page.php was first reported [3] by Mathias Karlsson 
(http://mathiaskarlsson.me) as part of Offensive Security's bug bounty 
program [4]; issue was also independently discovered and reported by 
Ryan Giobbi who made the original CVE request [2], Shahee Mirza [5] and 
Alejo Popovici [6].

Paul Richards also found another redirection issue in 
permalink_page.php, which turned out to have the same root cause.

The issue was fixed by Damien Regad (MantisBT Developer).
