I can see why you weren't able to find anything. However, there have been a number of disclosures that are probably related - but these were grep-and-gripe affairs in third party applications, where the researcher didn't necessarily investigate *why* certain attacks worked. Grepping for superglobal names through CVE suggests the following PHP application issues might be related to this behavior, although in some cases it could just be some extract() or dynamic variable evaluation or other method for overwriting critical variables: CVE-2007-1024 - _SERVER[DOCUMENT_ROOT] CVE-2006-4673 - _SERVER[REMOTE_ADDR] (might be extract) CVE-2006-4545 - _SERVER[DOCUMENT_ROOT] CVE-2006-3798 - _SERVER, _ENV, _COOKIE (extract) CVE-2006-1914 - GLOBALS, _SERVER CVE-2005-4318 - _SERVER[REMOTE_ADDR] CVE-2005-4317 - _SERVER[REMOTE_ADDR] CVE-2005-3926 - _SERVER[REMOTE_ADDR] CVE-2005-2574 - _SERVER[REMOTE_ADDR] (extract) CVE-2005-1996 - _SERVER[DOCUMENT_ROOT] CVE-2005-3300 - _FILES CVE-2007-0599 - SERVER CVE-2006-5796 - _SESSION[docroot_path] CVE-2006-5078 - _SESSION[dirMain] CVE-2006-2828 - import_request_variables(), but not for superglobals etc. - Steve
