RCE (or smth else) via:

  • Apache Commons Collections <= 3.1
  • Apache Commons Collections <= 4.0
  • Groovy <= 2.3.9
  • Spring Core <= 4.1.4 (?)
  • JDK <=7u21
  • Apache Commons BeanUtils 1.9.2 + Commons Collections <=3.1 + Commons Logging 1.2 (?)
  • BeanShell 2.0
  • Groovy 2.3.9
  • Jython 2.5.2
  • C3P0 0.9.5.2
  • Apache Commons Fileupload <= 1.3.1 (File uploading, DoS)
  • ROME 1.0
  • MyFaces
  • JRMPClient/JRMPListener
  • JSON
  • Hibernate

Additional tools (integration ysoserial with Burp Suite):
- JavaSerialKiller - Java Deserialization Scanner - Burp-ysoserial

Full shell (pipes, redirects and other stuff):
- $@|sh – Or: Getting a shell environment from Runtime.exec - Set String[] for Runtime.exec (patch ysoserial's payloads) - Shell Commands Converter

File uploading via:
- Apache Commons FileUpload <= 1.3 (CVE-2013-2186) and Oracle JDK < 7u40

Universal billion-laughs DoS

https://gist.github.com/coekie/a27cc406fc9f3dc7a70d

Won't fix DoS via default Java classes (JRE)

Universal Heap overflows DoS using Arrays and HashMaps

https://github.com/topolik/ois-dos/

How it works:
- Java Deserialization DoS - payloads

Won't fix DoS using default Java classes (JRE)

"Safe" deserialization

Some serialization libs are safe (or almost safe) https://github.com/mbechler/marshalsec

However, it's not a recomendation, but just a list of other libs that has been researched by someone:

  • JAXB
  • XmlBeans
  • Jibx
  • ProtobufGSON
  • GWT-RPC
