WordPress Plugin Is-human 1.4.2 – Remote Command Execution
# Exploit Title: is-human (1.4.2 and prior) Worpdress plugin. # Date: 16.05.2011 # Author: neworder [www.neworder-ind.net] # Software Link: http://wordpress.org/extend/plugins/is-human/ # Version: 1.4.2 # Tested on: Linux Platform The vulnerability exists in /is-human/engine.php . It is possible to take control of the eval() function via the 'type' parameter, when the 'action' is set to log-reset. From here we can run out own code. In order to avoid any errors we point the $is_hum->get_* array variable into $is_hum->get_ih and to close the execution without error we point it to php stored function error_log(). In between we may place our own php code and use the passthru() function to execute commands. Execution running the linux whoami command: http://server/wp-content/plugins/is-human/engine.php?action=log-reset&type=ih_options();passthru(whoami);error |
