An issue was discovered in EthereumJ 1.8.2. There is Unsafe Deserialization in ois.readObject in mine/Ethash.java and decoder.readObject in crypto/ECKey.java. When a node syncs and mines a new block, arbitrary OS commands can be run on the server.
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
