介绍

# CVE-2025-30065

This repository illustrates how to exploit CVE-2025-30065 and achieve remote class instantiation and  trigger a 
network request from within the victim application i.e the JVM thereby achieving SSRF.

The generated parquet in [Malicious.java](src%2Fmain%2Fjava%2Fcom%2Fevil%2FMalicious.java) assumes that the class [RCEPayload.java](src%2Fmain%2Fjava%2Fcom%2Fevil%2FRCEPayload.java)
is present in the classpath which is not realistic. You can trigger that PoC by executing [Reader.java](src%2Fmain%2Fjava%2Fcom%2Fvictim%2FReader.java).

[MaliciousSSRF.java](src%2Fmain%2Fjava%2Fcom%2Fevil%2FMaliciousSSRF.java) is more feasible (from an attacker perspective) and triggers a network connection which could be internal or external.
One could also find other gadgets to achieve RCE (what is tricky is to find an instructor accepting a string as arg and leading to a RCE it is not like plain java deser). 
Similarly, PoC can be executed using [ReaderSSRF.java](src%2Fmain%2Fjava%2Fcom%2Fvictim%2FReaderSSRF.java).
