Hace 2 días · Insecure deserialization is when user-controllable data is deserialized by a website. This potentially enables an attacker to manipulate serialized objects in order to pass harmful data into the application code. It is even possible to replace a serialized object with an object of an entirely different class.
¿Cuáles son los riesgos de Insecure Deserialization? La deserialización insegura permite a un atacante manipular objetos serializados para pasar datos dañinos al código de la aplicación, e incluso, reemplazar un objeto serializado por un objeto de una clase distinta.
Introduction. This article is focused on providing clear, actionable guidance for safely deserializing untrusted data in your applications. What is Deserialization. Serialization is the process of turning some object into a data format that can be restored later.
7 de dic. de 2017 · Insecure Deserialization is a vulnerability which occurs when untrusted data is used to abuse the logic of an application, inflict a denial of service (DoS) attack, or even execute arbitrary code upon it being deserialized. It also occupies the #8 spot in the OWASP Top 10 2017 list.

- The most important rule of web security is: never trust user input. This rule also applies to insecure deserialization vulnerabilities. To avoid th...
8 de jul. de 2022 · La serialización es un proceso que permite enviarle información sobre un código a un software. El término se utiliza para referirse a una sintaxis que permite almacenar comandos de programación, con el fin de comunicárselos a un software para que los ejecute.
It is expected that prevalence data for deserialization flaws will increase as tooling is developed to help identify and address it. The impact of deserialization flaws cannot be overstated. These flaws can lead to remote code execution attacks, one of the most serious attacks possible.
In this lesson, we will demonstrate an insecure deserialization attack by hacking an API of a video game company. Then, we will dive deeper into Java deserialization, explain the concept of a gadget, and study vulnerable Java code. Finally, we will cover how to mitigate this vulnerability.
