PHP remote file inclusion vulnerability in convert/mvcw_conver.php in the Virtual War (VWar) module for PHPNuke-Clan (PNC) 4.2.0 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the vwar_root parameter, a different vector than CVE-2006-1602.  NOTE: it is possible that this issue stems from a problem in VWar itself.
