Scanner SAST semantic-aware per applicazioni Node.js che rileva pattern di codice non sicuri utilizzando il pattern matching di libsast e l'analisi syntax-aware di semgrep.
# njsscan
**njsscan** è uno strumento di static application testing (SAST) in grado di individuare pattern di codice non sicuri nelle applicazioni Node.js utilizzando un semplice pattern matcher di [libsast](https://github.com/ajinabraham/libsast) e lo strumento di ricerca semantica di pattern di codice con riconoscimento della sintassi [semgrep](https://github.com/returntocorp/semgrep).

## nodejsscan SAST
**nodejsscan**, costruito sopra **njsscan**, fornisce un'interfaccia utente completa per la gestione delle vulnerabilità insieme ad altre utili integrazioni.
Vedi [nodejsscan](https://github.com/ajinabraham/nodejsscan)
## API Python
```python
>>> from njsscan.njsscan import NJSScan
>>> node_source = '/node_source/true_positives/sqli_node.js'
>>> scanner = NJSScan([node_source], json=True, check_controls=False)
>>> scanner.scan()
{
'templates': {},
'nodejs': {
'node_sqli_injection': {
'files': [{
'file_path': '/node_source/true_positives/sqli_node.js',
'match_position': (1, 24),
'match_lines': (4, 11),
'match_string': 'var employeeId = req.foo;\n\nvar sql = "SELECT * FROM trn_employee WHERE employee_id = " + employeeId;\n\n\n\nconnection.query(sql, function (error, results, fields) {\n\n if (error) {\n\n throw error;\n\n }\n\n console.log(results);'
}],
'metadata': {
'owasp': 'A1: Injection',
'cwe': "CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')",
'description': 'Untrusted input concatinated with raw SQL query can result in SQL Injection.',
'severity': 'ERROR'
}
}
},
'errors': []
}
```
## Configurare njsscan
Un file `.njsscan` nella directory radice del codice sorgente consente di configurare njsscan. È anche possibile utilizzare un file `.njsscan` personalizzato tramite l'argomento `--config`.
```yaml
---
- nodejs-extensions:
- .js
template-extensions:
- .new
- .hbs
- ''
ignore-filenames:
- skip.js
ignore-paths:
- __MACOSX
- skip_dir
- node_modules
ignore-extensions:
- .jsx
ignore-rules:
- regex_injection_dos
- pug_jade_template
severity-filter:
- WARNING
- ERROR
severity-overrides:
express_xss: WARNING
node_secret: ERROR
```
## Sopprimere i risultati
È possibile sopprimere i risultati dai file sorgente JavaScript aggiungendo il commento `// njsscan-ignore: rule_id1, rule_id2` alla riga che genera i risultati.
Esempio:
```javascript
app.get('/some/redirect', function (req, res) {
var target = req.param("target");
res.redirect(target); // njsscan-ignore: express_open_redirect
});
```
## Integrazioni CI/CD
È possibile abilitare njsscan nelle pipeline CI/CD o DevSecOps.
#### Github Action
Aggiungere quanto segue al file `.github/workflows/njsscan.yml`.
```yaml
name: njsscan
on:
push:
branches: [ master, main ]
pull_request:
branches: [ master, main ]
jobs:
njsscan:
runs-on: ubuntu-latest
name: njsscan check
steps:
- name: Checkout the code
uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 # v7.0.1
- uses: actions/setup-python@5fda3b95a4ea91299a34e894583c3862153e4b97 # v7.0.0
with:

- name: nodejsscan scan
id: njsscan
uses: ajinabraham/njsscan-action@231750a435d85095d33be7d192d52ec650625146 # v9
with:
args: '.'
```
Esempio: [dvna with njsscan github action](https://github.com/ajinabraham/dvna/actions?query=workflow%3Anjsscan)
#### Integrazione Github Code Scanning
Aggiungere quanto segue al file `.github/workflows/njsscan_sarif.yml`.
```yaml
name: njsscan sarif
on:
push:
branches: [ master, main ]
pull_request:
branches: [ master, main ]
jobs:
njsscan:
runs-on: ubuntu-latest
name: njsscan code scanning
steps:
- name: Checkout the code
uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 # v7.0.1
- uses: actions/setup-python@5fda3b95a4ea91299a34e894583c3862153e4b97 # v7.0.0
with:
python-version: '3.12'
- name: nodejsscan scan
id: njsscan
uses: ajinabraham/njsscan-action@231750a435d85095d33be7d192d52ec650625146 # v9
with:
args: '. --sarif --output results.sarif || true'
- name: Upload njsscan report
uses: github/codeql-action/upload-sarif@1c5b675653bb5c22dbe9b12b556ec555138e09fd # v4.38.1
with:
sarif_file: results.sarif
```
#### Gitlab CI/CD
Aggiungere quanto segue al file `.gitlab-ci.yml`.
```yaml
stages:
- test
njsscan:
image: python:3.12
stage: test
before_script:
- pip3 install --upgrade njsscan
script:
- njsscan . --gitlab-sast -o gl-sast-report.json
artifacts:
when: always
reports:
sast: gl-sast-report.json
```
Comando di esempio (locale):
```bash
njsscan . --gitlab-sast -o gl-sast-report.json
```
Questo genera un [report GitLab SAST](https://docs.gitlab.com/user/application_security/sast/) nativo, in modo che i risultati compaiano nel Vulnerability Report / widget di sicurezza delle MR senza un convertitore SARIF.
Esempio: [dvna with njsscan gitlab](https://gitlab.com/ajinabraham/dvna/-/jobs/602110439)
#### Travis CI
