Technical Analysis

Due to this being an unauthenticated serialization exploit, the bar for exploitation is very low. Serialization is rampant in software, and most companies aren’t doing it correctly.

It’s realtively easy these days to exploit serialization vulnerabilities with ysoserial/yososerial.net and it will be a problem for years going forward.
