- Summary
- Horovod Vulnerable to Command Injection
- Details
-
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_valuemethod inElasticRendezvousHandlercallscodec.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
