The truly frightening thing about an exploit using PHP is that the 
"bad code" can be as much user-generated as it is 
developer-generated. In other words, the clueless webmaster who 
copy/pastes code can unwittingly lead to the compromise of a server 
that s/he has even very limited user-level access on.

That and the vast variation of PHP versions we see still in use on 
various colo servers.


Another year, yet another variation of whack-a-mole.
