PHP Other Vulnerability - CVE-2007-1396

The import_request_variables function in PHP 4.0.7 through 4.4.6 and 5.x before 5.2.2 when called without a prefix does not prevent the (1) GET (2) POST (3) COOKIE (4) FILES (5) SERVER (6) SESSION and other superglobals from being overwritten which allows remote attackers to spoof source IP address and Referer data and have other unspecified impact. NOTE: it could be argued that this is a design limitation of PHP and that only the misuse of this feature i.e. implementation bugs in applications should be included in CVE. However it has been fixed by the vendor.
