Technical details
The vulnerability exists in the getInputStream function of the HttpServletRpcEndpoint component within NutzBoot's LiteRpc module (org.nutz.boot.starter.literpc.impl.endpoint.http.HttpServletRpcEndpoint.java). The flaw is an unsafe Java deserialization issue where untrusted serialized objects are deserialized without proper validation. An unauthenticated attacker can exploit this by sending malicious serialized payloads over the network to the HTTP RPC endpoint, achieving remote code execution. The attack has high complexity but is characterized as difficult to exploit, though public exploits are available. Patches and fixed versions should be checked with the Nutz Framework maintainers.
