My writeup on a "2,950-day" deserialization vulnerability in the GWT framework just went up. It's still unpatched 8 years later. To my knowledge no one has described how to exploit it publicly until now. If your organization uses GWT, you should read this.

It's likely exploitable without authentication, unless access control is handled by a non-GWT layer of the stack. My writeup includes a walkthrough of building and using payloads with a modified version of ysoserial: https://lnkd.in/gXwNcwzb

It didn't seem like there were any good examples to practice against, so I also built a sample vulnerable application to test your tooling: https://lnkd.in/gVs_YjVU
