Summary

Apache MINA versions from 3.0.0 through 3.0.0-M2 are affected. JavaNativeMessageDecoder in the MINA 3.0 codec module calls readObject() on frame bytes without a class filter, which is unsafe deserialization (CWE-502). An application that places this decoder in front of an untrusted peer lets a remote attacker achieve remote code execution through a gadget chain.

Description from the CNA

**UNSUPPORTED WHEN ASSIGNED** JavaNativeMessageDecoder in the MINA 3.0 codec module calls ObjectInputStream.readObject() on frame bytes with no class filter, so an application that puts it in front of an untrusted peer is open to gadget-chain RCE. As the 3.0.0 branch is inactive, we do not plan to release a version that fixes this issue. Users are recommended to use the latest Apache MINA 2.2.X branch.
