Overview
The PT Application Inspector plugin finds vulnerabilities and undocumented features in application code while it is being written (supported languages: PHP, Python, Java, JavaScript, TypeScript). Built-in analysis modules detect source code vulnerabilities, configuration file errors, and vulnerable third-party components and libraries used in the application development process.
How it works
Enabling and disabling the plugin
You can enable or disable the plugin in the open project folder. If it is not the first time you are opening the project, the plugin is enabled automatically (scan and action history is saved). You can also set up the plugin to be automatically enabled when a new project is opened.
When the plugin is enabled, the .ai folder is created in the project. This folder contains a database, log files, and a configuration file.
Installing the code analyzer
For the plugin to operate correctly, the PT Application Inspector code analyzer is required. You can install the analyzer in the Visual Studio Code interface by clicking Download analyzer in the pop-up window.
The path for code analyzer installation:
- In Windows:
%LOCALAPPDATA%\Application Inspector Analyzer
- In Linux:
~/application-inspector-analyzer
- In macOS:
/Library/Application-Inspector-Analyzer
Scanning a project
You can start a project scan in the following ways:
- By clicking [PT AI] Start scan in the status bar in the lower part of the window
- When saving project changes (if you selected On saving for the Trigger scan parameter)
- By running the command
PT Application Inspector: Start scan
- By running the command
PT Application Inspector: Start full scan.
Note. Before scanning, all changes to the project are automatically saved.
You can monitor the scan progress on the OUTPUT tab. The first scan usually takes longer due to the initial load on the database of vulnerable components.
General scan settings are configured in the aiproj.json configuration file. By running the command PT Application Inspector: Create project settings file, you can create a configuration file and configure scan settings in it.
Stopping a scan
You can stop a project scan by running the command PT Application Inspector: Stop scan or by clicking [PT AI] Stop scan in the status bar.
Analyzing scan results
You can find the list of all detected vulnerabilities on the PROBLEMS tab. If you click a vulnerability in the list, the line with its exit point gets highlighted in the code editor.
The [PT AI] DATA FLOW section contains a data-flow diagram that shows how each process converts its input data to output data and how processes interact.
The data-flow diagram consists of the following sections:
- Entry point. The starting point of the control flow.
- Data entry point. A file and code line with coordinates of data entry.
- Data changes. The description of one or several functions that modify potentially harmful input data. This section may not be displayed on the diagram if input data was not modified.
- Exit point. The execution line of a potentially vulnerable function. This is an exit point related to the vulnerability in the source code.
- Best place to fix. A code line best suited for patching a vulnerability. This section is displayed before the data flow.
You can go to the corresponding place in the code editor from any section of the data-flow diagram.
The [PT AI] EXPLOIT section contains an automatically generated HTTP request (exploit) that you can edit and use to check the vulnerability in a deployed web application.
Note. To exploit the vulnerability, specify the address of the host where your web application is deployed in the aiproj.json file. The default value is "localhost."
Note. To send an HTTP request, a third-party extension is required. It is recommended that you use the REST client.
Some vulnerabilities have additional exploitation conditions. They are displayed under [PT AI] ADDITIONAL CONDITIONS.
The contents of the [PT AI] sections depend on the code line selected in the editor.
When you scroll through the sections of the diagram, the vulnerability information is automatically pinned until you move on to another vulnerability. If you want to view information about a certain vulnerability while working on the code, you can pin this vulnerability manually.
Several vulnerabilities can have the same exit point. If these vulnerabilities belong to the same type, they are grouped together and displayed as one problem with different exploitation options. In [PT AI] sections, use the left and right arrows to view detailed information about such vulnerabilities.
Note. If you confirm one vulnerability from the group, the whole problem will be confirmed automatically. To discard an entire problem, you must discard all the vulnerabilities in the group.
Managing detected vulnerabilities
The PT Application Inspector plugin contains a set of tools for managing detected vulnerabilities. With these tools, you can do the following:
- Exclude vulnerabilities from scan results by selecting Suppress the vulnerability: exclude it from the PT AI scan results in the vulnerability context menu on the PROBLEMS tab
- Filter vulnerabilities by severity, status, and exclusion from scan results by running the command
PT Application Inspector: Show vulnerabilities.
- Confirm and discard vulnerabilities by clicking the X and checkmark buttons in [PT AI] sections
Comparing scan results
You can compare results of two scans within a project. To do this, under [PT AI] SCAN HISTORY, select the scans you need and then select Compare scan results in the context menu.
Note. The [PT AI] SCAN HISTORY section is displayed only in the developer mode.
Integration with PT AI Enterprise Edition
The PT Application Inspector plugin can be integrated with PT AI Enterprise Edition. The integration allows several team members to simultaneously work with vulnerabilities and their statuses in the IDE and PT AI Enterprise Edition web interface, thereby increasing the security of the code.
To configure the integration:
Enter the PT AI Enterprise Server URL and sign in to PT AI Enterprise Edition via your SSO system.
Synchronize a local project in Visual Studio Code and a project in PT AI Enterprise Server in one of the following ways:
Upload a local project to PT AI Enterprise Server
Connect a local project to an existing project in PT AI Enterprise Server
Download a project from PT AI Enterprise Server to a local file system
Work with code, scan, confirm, and discard vulnerabilities as you normally do.
The statuses of detected vulnerabilities are synchronized automatically, and all the team members can assess the current threat level.
For more information about the integration, see the PT AI Enterprise Edition User Guide.
