'Name' => 'phpBB viewtopic.php Arbitrary Code Execution',
'Description' => %q{
This module exploits two arbitrary PHP code execution flaws in the
phpBB forum system. The problem is that the 'highlight' parameter
in the 'viewtopic.php' script is not verified properly and will
allow an attacker to inject arbitrary code via preg_replace().
This vulnerability was introduced in revision 3076, and finally
fixed in revision 5166. According to the "tags" within their tree,
this corresponds to versions 2.0.4 through 2.0.15 (inclusive).
