Description: The Java deserialization vulnerability refers to a security risk that occurs when a Java application deserializes data that is untrusted. Deserialization is the process of converting a byte stream into a Java object, allowing data to be transferred and stored efficiently. However, if the data comes from an untrusted source, an attacker can manipulate the byte stream to inject malicious code. This can lead to arbitrary command execution, data alteration, or even complete control of the application. This vulnerability is particularly critical in applications and services that use deserialization to exchange information. The lack of proper validation of deserialized data can result in severe security breaches, making the implementation of security measures, such as input validation and the use of secure deserialization libraries, essential to protect applications. Insecure deserialization has been a common attack vector in various security breaches, highlighting the importance of addressing this vulnerability in the software development lifecycle.
