description: |
|
|
|
|
|
This template exploits an unauthenticated command injection vulnerability
|
|
|
|
|
in Klog Server versions 2.4.1 and prior.
|
|
|
|
|
|
|
|
|
|
The `authenticate.php` file uses the `user` HTTP POST parameter in a call
|
|
|
|
|
to the `shell_exec()` PHP function without appropriate input validation,
|
|
|
|
|
allowing arbitrary command execution as the apache user.
|
|
|
|
|
|
|
|
|
|
The sudo configuration permits the apache user to execute any command
|
|
|
|
|
as root without providing a password, resulting in privileged command
|
|
|
|
|
execution as root.
