Attack and Mitigation for Insecure Deserialization

This document discusses insecure deserialization attacks and ways to mitigate them. It describes how untrusted data can be exploited through deserialization to conduct denial of service attacks, reverse shells, and remote code execution. An example is given of a job search site that blindly trusts user input. The document then recommends never deserializing untrusted data and validating data integrity using techniques like SHA-256 and HMAC signatures to prevent attacks from compromising confidentiality, integrity and availability. It provides code examples of implementing these integrity checks on both the sending and receiving ends.
