CVE-2021-29508 — Insecure deserialization in Wire — CVE Details

CRITICAL

Insecure deserialization in Wire

Published May 19, 2021Updated February 17, 2024Source: osv

Summary

Due to how Wire handles type information in its serialization format, malicious payloads can be passed to a deserializer. e.g. using a surrogate on the sender end, an attacker can pass information about a different type for the receiving end. And by doing so allowing the serializer to create any type on the deserializing end. **This is the same issue that exists for .NET BinaryFormatter https://docs.microsoft.com/en-us/visualstudio/code-quality/ca2300?view=vs-2019** This also applies to the fork of Wire, AkkaDotNet/Hyperion.
