Introduction  
------------  
Eping is a simple php script executing the ping command,  
eping is an plugin for e107 portal system.  
Unfortunately a bug allows users to execute arbritary commands.  
  
More details  
------------  
The problem is based upon the fact that not all user inputs are filtered  
correctly. Variable $eping_host is not filtered using preg_replace.  
  
Proof of concept  
----------------  
You must put an evil code in $eping_host variable...  
Example: ?eping_host=127.0.0.1;ls...  
?eping_host=127.0.0.1;cd%20/;cat%20/etc/passwd...  
  
Security-Risk  
-------------  
Because an attacker is able to execute any php command, he is able to  
read all files including .htaccess or .htpasswd files or any password  
protected pages. Depending on system security he might be able to run  
any shell command on the server. That is why we are rating this security  
issue to high - very high.
