Why So Many Functions Disabled For Security???

[TheJeffsta]

OMG, I have installed MediaWiki, with a lot of code editing in the install script to get past some security disabled php functions.

Now that I am using the wiki, I keep getting this popen() disabled warning, this isnt all the time but some of the time, dont know what causes it, but its $@*&@ annoying!

What is soo bad about dl() and popen()?

[HyperCyber]

phpinfo() is desabled too lol

dl() - Loads the PHP extension given by the parameter library.
popen() - Opens a pipe to a process executed by forking the command given by command.

You can see why they are disabled.

Well then why do such innocent scripts use them :@, stupid php coders using disabled functions!

phpinfo() isnt a security risk :S

[Brandon]

phpinfo() is a security risk, as it reveals any extensions, kernel version, etc installed on our server. Sometimes this can be put in the wrong hands.

Stupid 'wrong hands' messing everything up for everyone else

Yes, DL is an extremely unsafe function allowing people to dynamically load whatever PHP modules they like.

We are working on 3 different types of PHP that can be changed for users upon request. Each version of PHP would allow the use of certain restricted functions for people we 'trust' with it. I wanted to roll that out this week but with all the problems and new users I haven't had much time to do anything but answer support requests and deal with server issues.

Hopefully we'll be able to do this soon.
