# QLinspector
Finding Java gadget chains with CodeQL.
More information in our [article](https://www.synacktiv.com/publications/finding-gadgets-like-its-2022.html)
## Installation
Clone the repo
```sh
$ git clone https://github.com/synacktiv/QLinspector.git
```
Search for gadgets:
```sh
$ codeql database analyze log4j --format=sarif-latest --output=log4j.sarif ./QLinspector/
```
## Queries
### `QLinspector.ql`
The main CodeQL query that can be used to find gadget chains.
here is an example with the Aspectj gadget chain:
Running the above query can sometimes return a lot of false positives. To filter them the `GadgetSanitizer` class has been added. You can add conditions to filter out `DataFlow::Node`:
```ql
/**
* placeholder for adding sanitizing steps
*/
class GadgetSanitizer extends DataFlow::Node {
GadgetSanitizer() {
this.getEnclosingCallable().hasName("")
}
}
```
### `QLinspectorOld.ql`
Old query that was initially developped. This query do not use the taint model of CodeQL thus it could return different results.
### `BeanFactoryGadgetFinder.ql`
A query that can be used to find new gadget chains based on the `org.apache.naming.factory.BeanFactory`. The `BeanFactory` class, allows to create an instance of arbitrary class with default constructor and call any public method with one `String` parameter.

### `CommonsBeanutilsGadgetFinder.ql`
A query that can be used to find alternatives to the `getOutputProperties` method used in the `CommonsBeanutils` chain.

### `ObjectFactoryFinder.ql`
A query that can be used to find alternatives to the `org.apache.naming.factory.BeanFactory`. This could be usefull during JNDI exploitation.
