"cat /proc/uptime" and "PHP"

17 Apr 2002

      Hi list,

i wrote a PHP script which reads the information given in /proc/uptime 
by executing "cat /proc/uptime".

<?PHP
   $prog = 'cat /proc/uptime';
   while ($i<count($prog)) {
   .
   .
   .
   }
?>

My question is: Is it safe to execute a external program when enetering 
a site? Or is it generally a security risk? Which severity would you 
give (1 - low, 10 - highest)?

Ciao ;-)
