I am new to CodeQL and therefore my apologies if my question is an obvious one, however, I've been unable to understand a few simple concepts.
Firstly, I can easily configure a public repo with a github action using a yml file configured as follows:
on:
push:
branches: [ master ]
pull_request:
# The branches below must be a subset of the branches above
branches: [ master ]
jobs:
analyze:
name: Analyze
runs-on: ubuntu-latest
permissions:
actions: read
contents: read
security-events: write
strategy:
fail-fast: false
matrix:
language: [ 'java' ]
# CodeQL supports [ 'cpp', 'csharp', 'go', 'java', 'javascript', 'python', 'ruby' ]
# Learn more about CodeQL language support at https://aka.ms/codeql-docs/language-support
steps:
- name: Checkout repository
uses: actions/checkout@v3
# Initializes the CodeQL tools for scanning.
- name: Initialize CodeQL
uses: github/codeql-action/init@v2
with:
queries: +security-extended
languages: ${{ matrix.language }}
# If you wish to specify custom queries, you can do so here or in a config file.
# By default, queries listed here will override any specified in a config file.
# Prefix the list here with "+" to use these queries and those in the config file.
# Details on CodeQL's query packs refer to : https://docs.github.com/en/code-security/code-scanning/automatically-scanning-your-code-for-vulnerabilities-and-errors/configuring-code-scanning#using-queries-in-ql-packs
# queries: security-extended,security-and-quality
# Autobuild attempts to build any compiled languages (C/C++, C#, or Java).
# If this step fails, then you should remove it and run the build manually (see below)
- name: Autobuild
uses: github/codeql-action/autobuild@v2
# ℹ️ Command-line programs to run using the OS shell.
# See https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstepsrun
# If the Autobuild fails above, remove it and uncomment the following three lines.
# modify them (or add more) to build your code if your project, please refer to the EXAMPLE below for guidance.
# - run: |
# echo "Run, Build Application using script"
# ./location_of_script_within_repo/buildscript.sh
- name: Perform CodeQL Analysis
uses: github/codeql-action/analyze@v2
As indicated in the yaml file, I'm using Java as the language. What I'm trying to then do is trigger a failure / alert with a simple code such as this in Java.
public class Main {
public static void main(String[] args) {
// Example code for https://cwe.mitre.org/data/definitions/476.html
String cmd = System.getProperty("cmd");
cmd = cmd.trim();
}
}
This simple code is an example from Common Weakness Enumeration (CWE) 416 where I'm trying to dereference a variable that hasn't been defined.
If I go to Security -> Code scanning alerts it will show that the scanning was performed but not alerts were found.
Basically, I'm wondering if I need to initialize the CodeQL with a specific CWE under the Initialize CodeQL step in the yaml file.
