Rule Vulnerability

Insecure Deserialization

Insecure Deserialization relates to web application security. Applications turn an object into data through serialization; the reverse of that process, deserialization, can be vulnerable to attacks when the application trusts the data that is being deserialized. Serialized data is machine readable and not encrypted; serialized user-supplied data should not be trusted. Deserialization attacks can lead to remote code execution.
