Unauthenticated Remote Code Execution in ElasticRendezvousHandler in horovod/horovod

Horovod versions up to and including v0.28.1 are vulnerable to unauthenticated remote code execution. The vulnerability is due to improper handling of base64-encoded data in the `ElasticRendezvousHandler`, a subclass of `KVStoreHandler`. Specifically, the `_put_value` method in `ElasticRendezvousHandler` calls `codec.loads_base64(value)`, which eventually invokes `cloudpickle.loads(decoded)`. This allows an attacker to send a malicious pickle object via a PUT request, leading to arbitrary code execution on the server.

Horovod 命令注入漏洞

Horovod是Horovod开源的一个 TensorFlow、Keras、PyTorc h和 Apache MXNet 的分布式训练框架。 Horovod v0.28.1及之前版本存在命令注入漏洞，该漏洞源于ElasticRendezvousHandler对base64编码数据处理不当，可能导致远程代码执行。
