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 (?)

File uploading via:

  • Apache Commons FileUpload <= 1.3 (CVE-2013-2186) and Oracle JDK < 7u40
Universal billion-laughs DoS

Won't fix DoS via default Java classes

Universal Heap overflows DoS using Arrays and HashMaps
