Advisory name: Arbitrary code execution in eping plugin Advisory number: 1 Application: eping Aplication author: apnovi3 Security-Risk: high - very high Remote-Exploit: Yes Discovered by: m00fd1 aka Tr|p
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.
The problem is based upon the fact that not all user inputs are filtered correctly. Variable $eping_host is not filtered using preg_replace.
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...
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.
