From: mccohy at kyberdigi.cz (C. McCohy) Subject: Re: php-exec-dir vulnerable after latest upgrade So, finally I have identified the problem, which was in fact, that the construction used for calling a command via the backtick operator did not use the php_escape_shell_cmd() internal function, which escapes some 'ugly/unwanted' characters, like '&', ';', '|' and others. This function is already used if the command is called via exec(), system() or popen() functions, so these were not vulnerable. New patches for all versions are available on the project homepage http://kyebrdigi.cz/projects/execdir -- Baj ... C. McCohy While you are reading this text, an essential hacking tool is being silently installed on your computer.
