Code Examples​

Compliant code​

Search for known vulnerabilities of any dependencies used on the code, replace them for safer alternatives

{
  "name": "test",
  "version": "1.0.0",
  "description": "nothing",
  "main": "index.js",
  "author": "Luis Saavedra",
  "license": "MIT",
  "private": false,
  "dependencies": {
    "@angular/core": "^13.3.3",
    "cloudron-sysadmin": "1.0.0",
  },
}

Non compliant code​

Example importing dependencies with known vulnerabilities

  }
}
dependencies {
  compile "io.springfox:springfox-swagger-ui:2.6.1"
  compile("io.springfox:springfox-swagger-ui")
  compile(group: 'javax.mail', name: 'mail')
  compileOnly group: 'org.apache.logging.log4j', name: 'log4j-core', version: '2.13.2'
  implementation group: 'org.json', name: 'json', version: '20160810'

}

Examples using software with known vulnerabilities

using System;
class ExampleClass{
  public void ExampleMethod(){
    //Is the URI is tainted, it may lead to parsing of a malicious XML schema
    XmlSchemaCollection xsc = new XmlSchemaCollection();
    xsc.Add("urn: bookstore - schema", "books.xsd");
  }
}
using System;
using System;
using System.Xml;
using System.Xml.XPath;
using System.Xml.Xsl;

namespace TestForXslTransform{
  class Program{
    static void Main(string[] args){
      XslTransform xslt = new XslTransform();
      xslt.Load("https://server/favorite.xsl");
      XPathDocument mydata = new XPathDocument("inputdata.xml");
      XmlWriter writer = new XmlTextWriter(Console.Out);
      xslt.Transform(mydata, null, writer, null);
    }
  }
