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 ofKVStoreHandler
. Specifically, the_put_value
method inElasticRendezvousHandler
callscodec.loads_base64(value)
, which eventually invokescloudpickle.loads(decoded)
. This allows an attacker to send a malicious pickle object via a PUT request, leading to arbitrary code execution on the server.References
