ID: 15187 Updated by: sesser Reported By: tozz@kijkt.tv Status: Bogus Bug Type: Scripting Engine problem Operating System: Linux 2.4 PHP Version: 4.1.1 New Comment: speaking of phpnuke... this security problem in phpnuke was reported a while back to its developers. if they havent fixed it by now blame them. Previous Comments: ------------------------------------------------------------------------ [2002-01-23 15:49:50] rasmus@php.net We can't stop developers from shooting themselves in the foot. If you want to include a remote file without parsing it locally, you would use: readfile("http://domain.com/filename"); You could of course also just use the allow_url_fopen directive in your php.ini file if you really want to turn this off. If you removed all the functions that developers could use to shoot themselves in the foot with there wouldn't be much left to do interesting things. ------------------------------------------------------------------------ [2002-01-23 15:42:16] tozz@kijkt.tv It's true dat this is a 'user error', however there are scripts (e.g. phpnuke has this problem) that allows a user to enter the URL that will be included. So, your right if a script is secure you wont deal with this bug.. but I still see it as a security issue ------------------------------------------------------------------------ [2002-01-23 15:37:30] sander@php.net This is bad programming. If you want to avoid this, you should NOT use include() for stuff on other servers, but fopen() or similar instead (which doesn't parse the data). BTW: the 'bug' in issue.php can be avoided by proper use of register_globals, safe-mode and/or normal (unix) file permissions. ------------------------------------------------------------------------ [2002-01-23 15:36:30] sesser@php.net RTFM! Include is for including PHP scripts into your PHP script. If you only want to include parsed output then do not use include. ------------------------------------------------------------------------ [2002-01-23 15:36:28] jan@php.net I call it a user error. no external sources are to be trusted with no error/security/integrity check. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
