Afrog explained for bug bounty hunters
Tags: webdev, hacktoberfest23, hacktoberfest, hackathon
Published: 2023-12-28 23:55:28


When working as a pentester or bug hunter it is normal to want to automate some of our work. This includes scanning network ports, checking the technologies in use, but also running potential exploits and vulnerability scanners. Today we will look at one tool that can help us automate our flow. We are talking about afrog.

## Afrog in action

We will skip all the configuration or installation steps because they are too simple to discuss. Instead, let's get straight to how the tool works. It supports user-defined PoCs and includes several built-in types such as CVE, CNVD, default passwords, information disclosure, fingerprint identification, unauthorized access, arbitrary file reading and command execution.

I took my old blog as the target of the attack. It is set up on wordpress and hasn't been updated for several weeks. We can run the tool with one defined target via a command:

```bash
afrog -t https://example.com
```

The appearance of the tool's operation in the console:

```bash
figaro@pop-os ~/D/t/afrog (main)> go run /home/figaro/Desktop/tmp/afrog/cmd/afrog/main.go -t https://example.pl
[INF] The reverse connection platform is not configured, which may affect the validation of certain RCE PoCs
[INF] go to `/home/figaro/.config/afrog/afrog-config.yaml` to configure the reverse connection platform

|	A F R O G	>	2.5.1	-	0.2.05

001 05-25 23:22:45 wordpress-login INFO https://example.pl/wp-login.php
002 05-25 23:22:51 CVE-2017-5487 MEDIUM https://example.pl/wp-json/wp/v2/users/
100% (894/894), 4m0s⏎                                                              
```

As you can see, we found one potential CVE at the medium level.

The tool, when finished, generates a report in the `reports` directory with a summary and analysis of detected PoCs. This is useful for further analysis and exploitation.

![afroge bug bounty](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xapx424uws3m84899tz0.jpg)

## Conclusion

The afrog tool is similiar to nuclei in its simplicity. Compared to it, it has ~8 times less stars on github (1.6k) which is still not bad and shows strong support for the tool. 984 commits and the last update (as of May 25, 2023) was 18 hours ago. Like nuclei, PoCs are defined in yaml format. The tool should be kept up to date, as it is worth watching and has a wide PoC base.

Dominando Object en JavaScript: Una Guía Completa
Tags: javascript, programming, webdev, spanish
Published: 2023-12-28 23:46:21

Para los desarrolladores de JavaScript que buscan excelencia profesional, comprender y utilizar eficientemente los objetos es muy importante. Los objetos son una de las estructuras de datos fundamentales en JavaScript, proporcionando una forma flexible y potente de organizar y manipular datos.

## ¿Qué es Object?
Un objeto en JavaScript es una colección de propiedades, donde cada propiedad es una asociación entre una clave (string o Symbol) y un valor. Los objetos son ideales para representar entidades con múltiples atributos y para estructurar datos complejos.

## Casos de Uso Comunes para Object
**Representación de Entidades**
Los objetos son perfectos para modelar entidades del mundo real o estructuras de datos complejas.

```javascript
const usuario = {
    nombre: 'Ana',
    edad: 30,
    email: 'ana@example.com'
};
```

**Agrupación de Funciones y Datos Relacionados (Namespacing)**
Usa objetos para agrupar funciones relacionadas y datos, reduciendo la posibilidad de conflictos en el espacio de nombres.

```javascript
const calculadora = {
    sumar: (a, b) => a + b,
    restar: (a, b) => a - b
};
```
**Configuraciones y Opciones**
Los objetos son una manera estándar y flexible de manejar configuraciones y opciones en funciones o librerías.

```javascript
const opcionesConexion = {
    host: 'localhost',
    puerto: 8080,
    protocolo: 'http'
};
```

## Operaciones y Propiedades Frecuentes de Object
**Acceso y Actualización de Propiedades**
Accede y actualiza propiedades utilizando la notación de punto o de corchetes.

```javascript
console.log(usuario.nombre); // 'Ana'
usuario.edad = 31;
```

**Enumeración de Propiedades**
Itera sobre las propiedades de un objeto con bucles como for...in o métodos como Object.keys.

```javascript
for (let clave in usuario) {
    if (usuario.hasOwnProperty(clave)) {
        console.log(`${clave}: ${usuario[clave]}`);
    }
}
```

**Extensión y Combinación de Objetos**
Combina propiedades de varios objetos en uno solo.

```javascript
const usuarioActualizado = {...usuario, activo: true};
```

## Mejores Prácticas y Tendencias del Mercado

- **Inmutabilidad:** Aunque los objetos en JavaScript son mutables, considera usar patrones como la desestructuración y el operador spread para evitar la modificación directa de objetos.
- **Encapsulamiento y Modularidad:** Utiliza objetos para encapsular y organizar tu código de manera modular, especialmente en aplicaciones grandes.
- **Clases y Prototipos:** Aprovecha las clases y la herencia prototípica para estructuras más complejas y la reutilización de código.

Los objetos en JavaScript son herramientas esenciales para cualquier desarrollador. Comprender cómo usarlos eficientemente te permitirá construir y mantener aplicaciones más robustas y escalables, aumentando significativamente tu valor como profesional en el mundo del desarrollo de software.

Dominando Map en JavaScript: Una Guía Completa
Tags: javascript, programming, webdev, spanish
Published: 2023-12-28 23:33:26

Para los desarrolladores de JavaScript que buscan alcanzar la excelencia profesional, comprender y emplear eficientemente Map es fundamental. Introducido en ES6, Map se distingue por su capacidad para manejar colecciones de pares clave-valor de manera eficiente y versátil.

## ¿Qué es Map?
Map es una colección de pares clave-valor donde cada clave es única. A diferencia de los objetos, las claves en Map pueden ser de cualquier tipo, y mantiene el orden de inserción de los elementos, lo que lo hace ideal para ciertos tipos de aplicaciones de datos.

## Casos de Uso Comunes para Map
**Manejo Eficiente de Pares Clave-Valor**
Utiliza Map para almacenar datos asociativos donde las claves no son simplemente cadenas o símbolos.

```javascript
const datosUsuario = new Map();
datosUsuario.set('nombre', 'Ana');
datosUsuario.set('edad', 30);
```
**Mantener el Orden de Inserción**
A diferencia de los objetos, Map recuerda el orden original de inserción de los elementos, lo que es útil en ciertas lógicas de programación.
```javascript
datosUsuario.set('hobby', 'fotografía');
for (let [clave, valor] of datosUsuario) {
    console.log(`${clave}: ${valor}`);
}
```
**Claves de Cualquier Tipo**
Map permite utilizar claves de cualquier tipo, incluyendo objetos, lo cual no es posible con los objetos literales.

```javascript
const claveObjeto = {};
datosUsuario.set(claveObjeto, 'Un valor único');
```

## Operaciones y Propiedades Frecuentes de Map

**Agregar Elementos (set)**
Añade un par clave-valor al Map.
```javascript
datosUsuario.set('activo', true);
```
**Eliminar Elementos (delete)**
Elimina un par clave-valor específico.

```javascript
datosUsuario.delete('activo');
```
**Verificar Existencia (has)**
Comprueba si una clave está presente en el Map.
```javascript
console.log(datosUsuario.has('nombre')); // true o false
```
**Tamaño del Map (size)**
Propiedad que devuelve el número de pares clave-valor.
```javascript
console.log(datosUsuario.size);
```
**Limpiar el Map (clear)**
Elimina todos los pares clave-valor.
```javascript
datosUsuario.clear();
```

## Mejores Prácticas y Tendencias del Mercado

- **Uso Adecuado:** Utiliza Map cuando necesites claves de varios tipos y quieras mantener el orden de inserción, o cuando necesites un rendimiento eficiente en la inserción y eliminación de elementos.
- **Inmutabilidad:** Considera la inmutabilidad cuando utilices Map. En lugar de modificar un Map, piensa en crear un nuevo Map con los cambios necesarios.
- **Rendimiento:** Map es generalmente más eficiente que los objetos para ciertas operaciones, especialmente en colecciones grandes.

Map en JavaScript es una estructura de datos poderosa y flexible, esencial para desarrolladores que buscan soluciones eficientes y claras para manejar colecciones de datos. Comprender y dominar Map y sus operaciones te posicionará como un desarrollador avanzado y competente, capaz de abordar una amplia gama de desafíos de programación de manera efectiva.
Dominando Set en JavaScript: Una Guía completa
Tags: javascript, programming, webdev, spanish
Published: 2023-12-28 23:20:26

Para los desarrolladores de JavaScript que aspiran a ser profesionales, comprender y utilizar eficientemente la estructura de datos Set es muy importante. Set es una característica introducida en ES6 que ofrece un manejo efectivo de colecciones de elementos únicos, diferenciándose de otras estructuras de datos por su simplicidad y eficiencia.

## ¿Qué es Set?
Set es una colección de valores en la que cada valor debe ser único. Los valores duplicados son automáticamente eliminados. Set es ideal para situaciones donde los valores deben ser únicos, y se manejan datos que no requieren un orden específico o indexación.

## Casos de Uso Comunes para Set
**Eliminar Duplicados** 
Utiliza Set para remover elementos duplicados de un array de manera eficiente.

```javascript
const numeros = [1, 2, 3, 2, 1];
const unicos = new Set(numeros);
console.log([...unicos]); // [1, 2, 3]
```
**Operaciones de Conjuntos** 
Set es útil para realizar operaciones de conjuntos, como la unión, intersección, y diferencia de conjuntos.

```javascript
const setA = new Set([1, 2, 3]);
const setB = new Set([2, 3, 4]);
const union = new Set([...setA, ...setB]);
```
**Almacenamiento de Elementos Únicos** 
Cuando necesitas una colección donde cada elemento es único y no quieres preocuparte por la verificación de duplicados.

```javascript
const visitantes = new Set();
visitantes.add('Juan');
visitantes.add('Ana');
visitantes.add('Juan'); // No se añadirá
```

## Operaciones y Propiedades Frecuentes de Set
**Agregar Elementos (add)** 
Añade un elemento al Set. Si el elemento ya existe, no se hace nada.

```javascript
visitantes.add('Luis');
```
**Eliminar Elementos (delete)**
Elimina un elemento específico del Set.

```javascript
visitantes.delete('Ana');
```
**Verificar Existencia (has)**
Comprueba si un elemento está presente en el Set.

```javascript
console.log(visitantes.has('Juan')); // true o false
```
**Tamaño del Conjunto (size)**
Propiedad que devuelve el número de elementos en el Set.

```javascript
console.log(visitantes.size); // Número de elementos
```

**Limpiar el Conjunto (clear)**
Elimina todos los elementos del Set.

```javascript
visitantes.clear();
```

## Mejores Prácticas y Tendencias del Mercado

- **Inmutabilidad:** Aunque los Sets son mutables, considera patrones inmutables cuando sea posible. Por ejemplo, en lugar de modificar un Set, crea uno nuevo con los cambios necesarios.
- **Optimización de Rendimiento:** Utiliza Set cuando el rendimiento en operaciones de búsqueda y eliminación de duplicados es importante, especialmente en colecciones grandes
- **Claridad en el Código:** Usa Set cuando su uso mejora la claridad y la intención del código, mostrando explícitamente que se trata de una colección de elementos únicos.

Set en JavaScript es una herramienta poderosa y eficiente para manejar colecciones de elementos únicos. Dominar Set y sus operaciones te permitirá abordar problemas comunes de manera más efectiva y eficiente, marcando la diferencia en tu carrera profesional.

Episode 23/51: TanStack Query in Angular, Alex Rickabaugh on Signals
Tags: webdev, javascript, angular, programming
Published: 2023-12-28 21:20:30

A Twitter Space session hosted by Daniel Glejzner, had some very insightful discussions on TanStack's Query version for Angular. Alex Rickabaugh on best practices regarding input setters, change detection runs, and Signals in general.

{% embed https://youtu.be/7ECYxNlVh8E %}

## TanStack Query

TanStack is a suite of libraries and well-known in React. Tan Query, probably the most popular one, is now available in Angular as an experimental mode.

Tan Query manages the data-fetching part but also caching, synchronization and other things. 

{% embed https://tanstack.com/query/v5/docs/angular/overview %}

Daniel Glejzner hosted a Twitter Space where you could get a first impression. The discussion centered on whether Tan Query is a state management library or something else.

Dominik Dorfmeister, co-maintainer of Tan Query, suggested that there are two different types of states. There is a state which only runs on the client and server state.
Server state is asynchronous, needs synchronization, and the client doesn't fully control it.

Tan Query was made for the server state. For client state, one of the common state management libraries, like NgRx, are a better fit.


{% embed https://twitter.com/DanielGlejzner/status/1737926230752551295 %}

## Alex Rickabaugh at Angular Nation

Alex Rickabaugh, Angular framework lead, was a guest at AngularNation. It was a must-watch episode, especially the discussions after his talk.

Alex explained in detail the reasons for Signals and created a form example. He showed that the main problem is that our model updates don't always follow the top-down change detection approach.

The common error we get here is the "Expression has changed after it was checked". We can work around it with asynchronous tasks, but there are still some obstacles, like with OnPush.

Signals will fix this.

---

In the discussion afterwards, Alex discouraged the usage of input setters. The problem is that Angular doesn't guarantee the order when multiple input properties get updated at once.
The recommended approach is still to use the hook ngOnChanges:

{% embed https://youtu.be/_yMrnSa2cTI?si=U3QOsIzxR-eTok-W&t=2498 %}

In terms of performance, fine-grained change detection might provide the best solution. In Alex' experience, it is almost never the case, that the change detection run itself is the bottleneck. Usually, it is that it runs too often. Again, with Signals, that problem is very likely to go away:

Easy to use JavaScript snippets.
Published: 2023-12-28 20:11:52

1.- Sort an array. 

```javascript
//strings
const names = ["Hello", "How", "Where"];
names.sort();
//['Hello', 'How', 'Where' ]

//Numbers
const numbers = [5, 1, 87];
numbers.sort((a, b) => {
  return a - b;
});
//[ 1, 5, 87 ]

//Sort array based on object:

data.sort((a, b) => a.name > b.name ? 1 : -1)

```

2.- Select a random element.

```javascript

const elements = ["Hell", "Can", "Use"];

const getRandomIndex = Math.floor(Math.random() * elements.length);

elements[getRandomIndex];

```

3.- Reverse a string. 

```javascript
const reverseString = (string) => string.split("").reverse().join("");

//Example
const stringReverse = reverseString("drag and drop a cover image");

```

4.- Check if element has class.

```javascript

const $elHaveClass = 
      	(el, className) => el.classList.contains(className);

// Example
//Check if the sidebar is open
const $elSidebar = document.querySelector(".sidebar");


const isSidebarOpen = $elHaveClass($elSidebar, 'sidebar__open');

```
